I have a Harbor Freight 44991 Mini Mill that I bought in 2006 or there abouts. My use of it has been off-and-on depending on what projects I had. Lately, I’ve been using it a lot and happened across a blog post talking about the benefits of upgrading from the gear drive to a belt drive using a mini mill belt drive conversion kit from LittleMachineShop.
There were two benefits that really caught my attention. First, I’d read that one of the key gears was nylon and could break. It hadn’t happened yet but given my machine is around 18 years old, it was concerning. Second, it could take care of the annoying loud whirring gear sound. I’d lived with it but I knew exactly what the author meant.
A company name Sieg in Shanghai actually makes these mini mills and they are sold under many different brands so if you have a Mini Mill from Harbor Freight, Grizzly, Micro Mark, Norther Tool, Sieg, Travers Tiiks, Wen and more, this ought to work. They tell you to confirm that the rear shaft is 9mm with a 3mm key and the front pulley that will go on the spindle has a 30mm bore and a 5mm key.
LittleMachineShop is my goto source for parts for my little mill and I aways had good luck with them. Overall, folks spoke highly of it so I ordered direct from them so I could get faster shipping. You can also buy it from Amazon if you prefer also [click here].
What arrived was a neatly done little kit with all the parts you need. A few people left comments on Amazon that they didn’t like the maching but what arrived for me was just fine.
This box was in another box – everything was packed very well. Note the small drive belt they include in case you ever need another. Gates 0130 or 2L130.This is the pully for the motor.This pully will go on the spindle.
Now, before you do anything read the instructions from their website. They also come with the kit and were on the bottom of the box. I through them one by one and found them to be detailed and accurate. There are a number of steps so I am going to post photos only of some of them – follow their instructions and you can do this.
They tell you this can be done in 15-20 minutes. It took me just over an hour as I had to fight to get the pinion gear off the motor because I couldn’t find any of my bearing/gear pullers so I blew time trying to find them and then making do with what I had.
So that’s the nylon gear everyone talks about. It connects to a steel gear on the motor (what could possibly go wrong). The nylon gear spins and sends power down to the Hi/Lo gear. The mill speed is set to high, you remove that gear and a snug fitting piece of clear tubing is put in its place just to keep the now-gearless shaft from falling. I found disassembly very easy until I got to this gear. The instructions say it may be tight. Well, it’s definitely a tight interference fit. Every fastener came off surprisingly easily but that gear is a pain.What would have made quick work of this would have been a bearing/pinion gear puller. Guess who couldn’t find his …. anywhere! So, I got a 17mm box end behind and levered it out part way and then used a big flat head screwdriver where the head was bevelled. I’d lightly tap the screwdriver down and as the wedge-shaped head moved down, the gear moved out. I just had to be careful not to lose the Woodruf key that holds the gear in place relative to the shaft. I was able to slowly work it out. The only causualty was knocking paint off the motor as it moved around.My pile of parts grew. I like using a magnetic tray to hold everything. I scooted everything left over into a heavy ZipLoc type bag and stored it in my mill’s toolbox.
I kept following the instructions and everything went together real easily. I’m actually impressed that they were clearly described and complete.
Now there was one catch – they told me to use my old spindle lock pin when I was putting the spindle nut back on. Maybe there’s been a design change in the 18 years since I bought mine but my original spindle lock was 7.865mm and far too big to go in the new top plate’s hole. I found I could get a handy roll pin punch (6.42mm) to fit albeit with a little slop in the locked spindle. My original spindle stop pin had a diameter of 7.865mm according to my Mitutoyo micrometer. I used some drill bit shafts to get an idea of the size rod I needed. 6.5mm fits through the hole and is about as large as I can go. I toyed with filing the hole open larger to fit a bigger pin but think this will hold up ok. It doesn’t have to withstand a lot of torque.Here’s a side view. Note the paint scuffed off the black motor from my hear removal shenanigans. Note hole for the locking pin.Looking down at it a bit.With the cover.
Summary
I can’t say that the sound level went down much but it did change. More of a whirring sound instead of the gears meshing. Running at max speed on the low speed pulley, my sound meter is reading 90-92db while sitting on the table right below the spindle.
For me, the most important thing is that I don’t have to worry about one of the gears breaking. I’m pleased with it because that was what I really cared about.
If you want to upgrade your mini mill so you don’t have to worry about the gears, The LittleMachineShop belt drive conversion kit is pretty slick.
I hope this helps you out.
Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

I have a Harbor Freight 44991 mini mill that I bought it in 2006 if I recall right – it’s been so long that I don’t actually remember at this point. It’s served me well but like anything, stuff happens with age. In this case, the mini mill way covers were breaking down due to oxidation and repeated flexing.
I’ve replaced the way covers a few times over the years but this time had a challenge finding any in stock. In general, my goto spot for mini mill parts is LittleMachineShop.com and I recommend them to anyone with a mini mill or lathe. They’ve been out of stock for a while now and I wanted a solution sooner instead of later. I was adjusting my mill, cleaning it up in general and wanted to get the covers on so the ways would stay clean.
If you are new to machining, way covers aren’t just cosmetic. They keep debris off the ways (the machined surfaces that move on the X-Y table). If you don’t keep the ways clean you run the risk of something getting under the table and throwing it off or even just making cranking the handles harder.
So, I needed to find another source but where? I had to figure out an alternative. Way covers have a diameter and length – how hard can it be if I searched using the measures and adapted whatever I found? The answer is that making your own is surprisingly easy. The way covers for the 44991 mini mill, and the two dozen or so brands that are actually the same machine made by Sieg in Shanghai, are 200mm wide and that’s the key – looking for millimeters vs. inches.
My initial mistake was to try and find a cover with a width between 7.75 and 8 inches. Then it dawned on me that the machine’s parts are actually metric and the width was 200mm. I figured if I could find a long enough length I would just cut it down and that strategy worked. By the way, that’s a 12″ IGaging Absolute Origin caliper. It’s a rare job where I need to measure something bigger than my 6″ Mitutoyo caliper can handle. For those rare occasions, the IGaging caliper has been good enough for me.
Armed with that, I immediately found way covers on Amazon. They are really long but you can cut them down with a plain sharp knife and straight edge no problem. Click here for the listing. At the time of purchase, they had one review. I was in a rush and figured I would gamble $10.19 not including a 5% off coupon. It was shipped from China and took about two weeks to arrive.
Guess what? They are actually really decent. Instead of rubber, these way covers are some kind of rubberised fabric. I’m not even sure rubber is the correct term and cutting them down to fit is fast and easy with plenty left over for a few more replacements (I stored the remainder in a heavy ziploc industrial bag and actually purged it with nitrogen. Yeah, I work with plastics so I have access to that stuff. Just sealing it in a good ziploc-type bag and keeping it safe would probably work too.
Let’s Step Through The Process
I did my covers one at a time starting with the front. The cover is held in place by a bracket on each end. Each bracket is held in place by two Phillips round head screws. Remove the brackets and the covers. Note the front cover has two sizes of screws when you go to reassemble it.
Each way cover is held in place by a metal strip and two Phillips round head metric screws. Note, on the front way the front and back screws are two different sizes so pay attention what goes where (the larger diameter screws are to the back if I recall correctly). This is either my second or third set of rubber way covers. They slowly break down with time and use.
With the cover off, I cleaned and lubed the ways and also the threaded rod. I then moved on to make the cover.
I removed the front cover and took the time to clean and lube the ways and threaded rod.The old way cover is to the right. The 200mm x 1500mm new way cover is to the left. It turns out the folds are 1.5cm on both so I just counted the peaks and made my cut. If the fold height didn’t match then I would have fit it based on the smoothed out length.I cut the length of new cover I needed and then used the old brackets to mark the hole locations.I marked the holes and then used a revolving hole punch plier to approximate the openings. I actually own a hole punch set but I don’t know where I put it – that would have been more elegant than my nibbling around the circle with the pliers but I got the job done.
I then did the same for the back and installed the way covers on the mini mill. The next time I do them, I may glue a plastic strip on each end to make it a tad more secure at each end but what I have is working great.
Looks much, much better and the ways are once again protected. It’s a tad floppy at the ends and next time I will add either a small steel or plastic strip the full width of the cover, scuff both sides for a good grip and join them with Starbond black super glue. The cover is perfectly serviceable as-is for now but am keeping that in mind for the future. By the way, that is a Dayton CNC 12″ workholding plate. I have two of them and they’re great. Here’s the link and the wait time is about 2-4 weeks. The positioning strips are from a vendor called Bulk Man 3D on AliExpress. All the holes and fasteners are 1/4-20 and the metric strips can accomodate 1/4-20 socket head screws in case you are wondering.I’m not sure what this material is but have a suspicion it will hold up better than the rubber. Time, use and exposure to lubricants will tell though. I’ve only had them on for over a week but cutting oil and penetrating oil don’t appear to have affected the material thus far.
Summary
The new way covers are working great. You can make your own and have plenty left over for the next time plus it is cheaper regardless. I have no problem recommending you buy this way cover and cut it to fit. I do suspect it will hold up better than rubber given it is fabric reinforced and not just plain rubber and we’ll see if that proves to be true.
I hope this helps you out.

I’ve heard about using ultrasonic cleaners on firearms for years but never really investigated them. Recently, I had a need to clean a bunch of HK33 grips that had cosmoline, oil, and whatever else on them. Actually, I knew well in advance because they were part of a project and I had to figure out how to clean up a 50+ of these used grimy grips.
The HK 33 grips had cosmoline on them.
My Cleaning Options
I knew cleaning that many by hand with a solvent would take forever and be expensive. Hot water and dish soap was an option but slow and time consuming. An ultrasonic cleaner seemed like a perfect solution. I talked it over with my friend Scott, who owns Michigan Gun Exchange. Scott has one in his shop and uses it to clean firearms. He showed me how it worked and I was impressed. This type of cleaning would be perfect.
Ultrasonic Cleaners
An ultrasonic cleaner cleans parts three ways – the liquid bath, ultrasonic vibrations and heat all combined at once. If you’ve every fought getting cosmoline or old grease that has set up, you know how heat is your friend.
Okay, it was time to research. I couldn’t afford or have the space for a giant unit. Doing some digging, the Vevor 30 liter unit got good reviews and looked like it would work for the majority of firearm parts I would need to put in it. I considered the length, width, height and the diagonal for really long parts. The stainless basket you put the parts in measures 18.3″ x 10.8″ x 6.7″. The diagonal is 21.25″.
Note, in terms of actual volume it holds, they say the unit is 30 liters in the title but also report that it measures between 29 and 30 liters or 7.7-7.9 gallons. They recommend the fluid be at least 75% full to protect the heating element plus you never run an ultrasonic cleaner dry or it can damage the unit.
By the way, on a larger unit like this, make sure it has a drain valve and the Vevor 30L does.
This is the Vevor 30L cleaner. The unit is simple to operate with the temperature on the left and the timer on the right,
Deciding On The Solvent To Use
Dedicated ultrasonic cleaner fluids are rediculously expensive. What a lot of gun guys do is to use 50:50 Simple Green and water. I started reading more on that and there was one small detail I wanted to avoid – aluminum left in plain Simple Green for too long is apt to react and cause pitting. The aluminum friendly formulation is Simple Green Pro HD.
I’d recommend using Simpe Green Pro HD because it is aluminum friendly. I know guys using the regular Simple Green at a 50:50 ratio and they aren’t having problems – my suspicion is that the parts in the liquid long enough for a problem to happen.
Simple Green’s recommended ratios for their Pro HD formulation are:
For heavy cleaning: 1 part Pro HD to 3 parts water
For medium cleaning: 1 part Pro HD to 5 parts water
For light cleaning: 1 part Pro HD to 10 parts water
Well, given how thick cosmoline, grease and oil can be, I went with the heavy cleaning 1:3 ratio and it worked great.
Two comments – first, I bought mine from Home Depot. They ship to a home for free in my area. Amazon is rediculously expensive due to the weight. Second, I didn’t find out until later that Simple Green also has an “Extreme Aircraft and Precision Cleaner” formula. I might try that in the future as they expressly made it to not react with plastics, composites, aluminum, etc.
Heating the Tank
One complaint of folks using the large ultrasonic cleaners is that their internal heaters take hours to heat the fluid up. Well, I can’t wait hours so did some digging on that front and bought an immersion heater. They all have a potential shock hazard so you do not want to put your hand in the fluid while heating it.
I bought an immersion heater made by HAIYEATBNB off Amazon. because it has a temperature regulator and got good reviews — it’s a game changer. Scott bought one after I told him how fast it heated the tank.
To be clear, the immersion heater is to dramatically speed up the heating of the solvent and then it is removed. A quick summary of steps is to put the heater in the fluid, plug in the unit and set the temperature, let it heat it up, unplug the heater, let it cool off a tad before you remove it and set it in a container so it doesn’t drip. The Vevor cleaner’s internal heating unit can maintain the temperature. The immersion heater is just fast forwarding the heating process.
The recommended temperature range for ultrasonic cleaners range from 130-180 degrees Farenheit. The theortetical “best” temperature for cavitation is 158F (70C) and guys report great luck between 155 and 165. Just bear in mind that the hotter you go, the more evaporation you will have also.
This is the HAIYEATBNB immersion heater. I like having the temperature control and the actual heating element contained inside the metal shield that has the stars on it. Yeah, I am sure the shape will cause some jokes but it works quite nicely.
The immersion heater sped things up dramatically. I could bring the tank up to temperature in 30-40 minutes. The exact time depends on the volume of liquid and what the starting temperature of the fluid is.
The immersion heater’s temperature gauge will not match the ultrasonic cleaner’s temperature gauge. If you want to know the actual temperature more accurately, you use a more precise instrument such as my Fluke 62 Max+ shown here. Note, the temperatures will vary depending on where you point it. At some point you just have to say “close enough” and call it even.
Safety comment: There is the potential for electric shock with any immersion heater. We used them on our farm growing up and survived. I’m not too sure I would worry about any freaked out electric shock comments you see in all of the reviews on Amazon across most of the heaters I looked at. Simply put, avoid sticking your hand in there while it is heating. Standing barefoot in a puddle of water that has an earth ground while putting your hand in the solvent during operation of the immersion heater will get you shocked so don’t do that!! Sheesh.
Testing
I timed the ordering with everything arriving so I could immediately put the unit into use. If it was going to fail, I wanted to know as soon as possible so I could return it.
In terms of fluid, Vevor recommends you have at least three quarters full or you may damage the unit. If the fluid capacity is about 7.7 gallons then this puts it at 5.8 gallons of fluid. (The above photos do not reflect this just to be clear – I had about three to four gallons in when I snapped them.)
I then put in the immersion heater and watched the temperatures climb both on the heater and cleaner’s gauges and they didn’t match. That really wasn’t surprising to me. It’s hard to say which is more accurate but I decided to go with the temperature measurement from the Vevor cleaner. They claim their temperature reading is within +/- 5 degrees celsius which would be about +/- 9 degress Farenheit if I am doing my math right.
Given the size of the unit I could easily put two grip modules in side by side and that’s what I did. I didn’t try stacking them as that might reduce the cleaning effectiveness. I put the unit’s timer at five minutes and let it run. It was fascinating to watch the crud come off – even the red and white paint filler in the S-U-O symbols on the grip were dissolving.
The cleaner was fascinating to watch operate. I took this photo because you caan see the paint dissolving from the selector position marks.
I read a few complaints about the noise these things generate. The Vevor makes a buzzing sound for sure. Maybe it’s just me but it really didn’t bother me. I didn’t need it to be quiet – I needed it to clean stuff.
The timer went off, I then removed the units, sprayed them down with water to remove the cleaner and then used an air line to blow all of the water out.
The results were amazing. Scott had warned me that everything comes off – including the “sheen” of the black plastic resulting in a dull charcoal color. I then went on to do about a dozen more. In two or threee cases there was still some caked on cosmoline inside the grips that a second pass got rid of.
The results were very impressive. In just a few cases did I run a grip through a second time.
Have A Plan to Avoid Rusting Afterwards
I should tell you to have a game plan to avoid flash rust forming on steel items you clean. Ultrasonic cleaners will strip all the oil and grease off so that means untreated steel can form rust when exposed to moisture in the air. “Flash rusting” is a term for when bare steel is exposed to moisture in the air and starts to show visible rust within minutes of exposure.
Spraying WD-40 can help displace water – another option is to use compressed air if you have access to all surfaces – first but then you need something to prevent rust such as a light spray oil or whatever your preference is. My point is to think it through to avoid flash rusting after you clean.
Summary
At this point, I am very happy with the Vevor 30L ultrasonic cleaner. If you have ever wanted to get into ultrasonic cleaning for whatever you are working on, the Vevor units are cost effective and you just need to decide on what size works for you. Click here for a listing of Vevor cleaners on Amazon and here for all brands.
I hope this helps you out.
Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

Hi folks – back in 2020, I wrote about buying a Mophorn 3 ton pneumatic/air- pillow jack to work on our vehicles. Actually, I bought it in 2019 and it’s still going strong. This past Fall, I decided to get a second air bag jack but decided to get one with a higher lift capacity to better jack up my 2021 Ram 2500.
To give some background, I wanted an air-pillow/air-bag lift for speed and to save my shoulders that could no longer handle pumping a hydraulic jack arm over and over to lift a vehicle. I have an air-over-hydraulic bottle jack but it is tall and slow. The air bag jacks use compressed air to inflate a rubber cylinder that then lifts the vehicle – like what you see in air-ride or air-lift suspensions on trucks. They are called by a variety of names as you can see in this post: pneumatic jacks, air bag jacks, air pllow jacks, pillow lift jacks. Air-over-hydraulic is a different creature – air is used to actuate the hydraulic pump vs. you hand pumping to move the hydraulic pump up.
Always Use Jack Stands
Once the vehicle is in the air, I always put jack stands all the way around to support it. This is always a good idea regardless of jack type you use and the air bag jacks are no different.
There was one thing in their product page on Amazon that confused me until I realized it was a metric term. They say it can lift 11,023 pounds / 5 tons. Well, being used to American measures, 5 tons if 10,000 pounds soI wondered if this was some kind of hype. The issue is that they mean 5 metric tons. A metric ton is 1,000 KG or 2,204.6 so 5 metric tons is 11,023 pounds.
Their stated operating air pressure range is 5-10 kg/cm^2. That comes out to 71.1 to 142.2 PSI. The airline for my driveway tools is at 100 PSI – most of my tools are 90 PSI. My guess is that given their operating range, the jack can’t lift its rated maximum capacity. I can tell you that it has no problem lifting the front or rear of either my 6.7L Hemi 2021 Ram 2500 or full size 2016 Ford Transit F150 van and that’s really what I wanted. The photo at the top of the blog is the Vevor with my Ram 2500 up in the air.
The lifting height is about 15.75″ and the minimum height is 5.3″. The minimum matters a lot when you are trying to get it under some vehicles. One trick I have found is to stand on the air bag to get the air out and then close the exhaust valve to make it thin enough to slide under some cars.
The Mophorn is slightly taller and you can see the Vevor has a larger diameter air bag.
One of the nice perks is that the handle has three positions so you can slide it in flat under a vehicle or at an angle if so you choose. My Mophorn jack’s handle is in a fixed position so that limits how far it can slide under some vehicles but it’s also more sturdy since it can’t move.
You can see the difference between the fixed Mophorn handle vs the 3-position Vevor.
With the Mophorn jack, the screws securing the botton of the bag to the plate started to come loose and the unit was leaking air. With the Vevor, they are in solid and really did not want to back off – I was going to add medium Loc-Tite but since they were in so firmly, I decided to leave them alone. They may even have a thread locker applied already – I’m not sure. I think out of all of the screws there were only one or two I could torque down further.
The Vevor has no problem lifting my Ram 2500 with 100 PSI of air.
Summary
All in all, the Vevor air bag lift seems like a solid unit. I’ve not had any problems at all. I sometimes wish the handle wouldn’t move so easily but its ability to fold flat to the ground makes up for that.

In September I bought my first new truck from a dealership – a 2021 RAM 2500 with the 6.4L Hemi engine. It was a Tradesman with a crew cab and the 2GA customer package group – meaning it had the Snow Chief, Chrome Appearance, Tradesman Level 2, Shift on the Fly transfer case, Power Black Trailer Mirrors, LED bed lighting, and Trailer controller. What it didn’t have was front tow hooks — seriously. I was actually surprised by this. I’ve used front hooks so many times over the years that to not have them wasn’t an option but I figured I could add them later and bought the truck.
Wow – Have You Seen The Price To Add Hooks?
Well, this surprised me. I shouldn’t have assumed the cost wouldn’t be bad. Let me itemize this for you real quick:
Tow Hook – Mopar 68349551AD List $132 Online around $93.36 each – you need two
4 hex flange mounting screws / bolts – Mopar 6512808AA. List $5.10/ea and online they are around $3.84/ea. Again, you need four of them – two for each hook
4 hex flange lock nuts – Mopar 6512809AA. List is $5.10 each and online is about $3.84/ea. Thread is M16x1.50mm. Again, you need four of them – two for each tow hook.
That adds up fast. The list total is $304.80 and online is $217.44 – a savings of $87.36 but that does not include shipping or taxes
This does not include the bezels / changes to the bumper if you do it by the book
This does not reflect labor of maybe 2-3 hours or the shop supply charge either.
Also, confirm with the supplier if they have something before you buy it. When I was looking, hooks were hard to find in stock at any kind of discount plus some dealers say they have things but they do not.
So, this definitely wasn’t looking cheap either in terms of parts or labor if I had a dealer do it or even if I went will all new Mopar parts.
How to save money and not sacrifice quality?
What is quality? Quality means meeting my requirements and what did I require? I cared about brute strength. I talked to some guys and they all told me to go with the Ram hooks but to get them off eBay because salvage yards put them up for sale at a huge savings. Wow, they were right. You can get both hooks off eBay that look like new for less than half the price but usually with no fasteners included.
Search on eBay for 68349551ac or 68349551ad tow hooks. The letter designators (aa, ab, ac, and ad) tells us there have been minor changes and the most current version as of my writing this is the “ad” release. I can’t speak to all of the versions but I can tell you I am using the “ac” hooks, no problem. You could search for an earlier release such as “aa” or “ab” if you wanted – I’m just telling you what I did. If you can get a great deal on the newest version, go for it.
When I looked at the Mopar site, it seems to be the hook for all of the trim styles (Tradesman, Big Horn, Laramie, Limited, Limited Longhorn, Lone Star and Power Wagon) of both the 2500 and 3500 series trucks for 2019-2021.
Note: some eBay sellers list two hooks (meaning the pair) in an eBay listing and some just list one so pay attention.
I also always look at how many sales they have done and their rating as well. I’ll pay more for an established seller vs. gambling on a seeming deal from a relatively unknown seller.
I also noticed some sellers put all of the part numbers in their description so searches pull them up so read the listing carefully.
Click on the following to search for:
The 68349551ac hooks (this is what I bought and installed on my 2021 Ram 2500 Tradesman)
By the way, the RAM 1500 hook is not the same so make sure you get a 2500 hook for your model year truck.
Okay, for the bolts and nuts, I did actually go with Mopar and bought them online. I have read posts of fellows going to the hardware store and buying Grade 8 – 5/8″ x 4-1/2″ long bolts, washers, lock washers and nuts. It’s an option but I didn’t want to gamble with the metallurgy so I bought the bolts and washers from https://store.mopar.com/ and there are other online sellers you could go to as well.
As far as the bezels and stuff go, honestly, just cut the fake plastic grill out of the way. Yeah, you could spend the time and money to make it look factory but this is a work truck and the tow hooks are near the bottom of the bumper so nobody is going to be looking for the bezel behind realistically.
As for labor, you can totally do this yourself in less than an hour. I think it took me about 30 minutes.
These arrived via USPS Priority Mail maybe 2-3 days after I ordered them. They are like new – I doubt they were ever used. Yes, they do weigh a ton. I guess I could have weighed them but that didn’t occur to me as I really didn’t care. The point is that they sure are beefy. These are the 68349551AC series hooks by the way.
Installing The Hooks
You can totally do this if you are comfortable with cutting on your truck (some guys aren’t and that is okay – find a buddy who is and bribe him/her with beer, BBQ or whatever) and can turn a wrench. I kid you not, you only need a 15/16″ socket, 2-4″ extension and a big ratchet wrench to do this after your cut the little grills out of the way. A torque wrench capable of 80-90 foot pounds is handy but not essential.
This is my 2021 Ram 2500 Tradesman. The hooks go in the openings located right under the left and right sides of the main grill or the next opening over from where the fog light covers are.
That is the driver’s side tow hook opening with the soon to be cut out plastic grill in the way.
The part of the frame rail where the town gook goes is that square opening straight back from the center so I planned to cut the top three horizontal pieces out of the way.
This is an Ingersoll Rand model 529 reciprocating saw used for body work and what not. This thing is amazing. Cheap reciprocating saws have a ton of vibration when they run but not this one. It makes cutting sheet metal as easy as soft grill plastic 🙂 This is a fine 24 tooth blade. Use a fine blade on plastic to avoid any snags and tears. Your other option is to look for one of the small hack saw blade holders or other small saw where you can reach in. The more teeth per inch, the better.
This is right after cutting. I haven’t cleaned up the cuts or blown out the plastic cuttings yet. The tow hook will go straight into that center opening and you will need to jiggle the hook around to get the two bolts through.
This is what I cut out. A fine tooth saw really does a nice job – fast and clean.
Here are the hooks, bolts and buts.
I wanted you to see the side profile of where the bolts engage the hook. The front groove actually has a retaining ring cast into it. I installed the front bolt first – and it will take some wiggling around to get it in and then I did the rear. I did all of this with the truck on the ground by the way, Also, I think the design is pretty interesting. They know the force will be applied by pulling forward so that is where they put their emphasis. The sides of the frame rail clamping against the sides of the hook will further lock it in place not to mention the inevitable rust that will happen sooner or later.
/lbThese are the four Mopar bolts and lock nuts. The wings/tabs on the nuts go into openings in the frames so you can focus on tightening the bolt down to 80-90 ft/lbs. They also limit travel of the nut over time to keep the whole assembly secure.
So push the bolts from the outside of rain through to the inside. This is the driver’s side.
So here you can see the bolts with the lock nuts in place.
This is the passenger side. I had just started the bolts into the nuts when I took this picture.
Torque Down The Bolts
Some guys reported that their hooks rattled and I think they were not torquing them down enough. Yes, they will rattle when you insert them in the frame but not once you tighten them down. Thanks to the WWW, I could not find an absolute “here’s what RAM said for the 2500 tow hook” torque spec. I saw numbers all over the board.
I took a different tact, Mopar says the nut is a M16x1.5 on their website so when I look that up, a class 8.8 bolt has a 245 Nm spec and a class 10.9 has a 335 Nm spec. Converting 245 Nm to ft lbs gives us 180.7 ft lbs. Wow. I divided that by half and took the nuts to 90 ft lbs and called it even. No rattling and the hooks feel solid as a rock. If they loosen up, which I highly doubt, I’ll search around again for the torque spec and/or apply Loc-Tite. Given the design of the locking nuts, I really do not think this is going to happen.
If you don’t believe in torque wrenches, do whatever works for you. Due to a variety of nerve factors, I can’t feel how much pressure I am applying any longer so I torque stuff down to spec.
If you do know a definitive value, please email me and I’ll adjust accordingly.
This is big Ed my 50-250 ft lb 1/2″ torque wrench. I have “bigger Ed” that is a giant 3/4″ unit. I also have a number of 1/4, 3/8 and 1/2 torque wrenches for different applications.
The Result
They are rock solid. I haven’t used them yet but am ready for winter.
Driver’s side. I think I could have left the one top section of the grill but I am also not sure if it would have gotten busted off anyways from shackles, hooks, etc. I also can’t get rid of the slight angle of the hook left to right despite trying to make it flat several times so I am not going to worry about that either,
Passenger side
One last comment, I did go in a week or two later and spray painted all of the exposed bolts and nuts with black paint to slow up the rust on the fasteners. In Michigan, fighting rust is an art form and also a losing battle – that salt that gets put on the roads gets everywhere and eventually takes its toll but I sure do try to delay that 🙂
Summary
You can definitely do the hooks yourself. Save some money and get them off eBay, do what you want with the bolts and then trim the front grills so the tow hooks can slide in. It looks pretty good and will do the job.
Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

Okay, I’m the proud new owner of a 2021 Ram 2500 Tradesman and the original halogen lights were pretty anemic. I did two things to address this – first, I replaced the high beams with Lasfit LED emitters and that’s a story for another day. With that said though, I’ll tell you that upgrading to the Lasfit LED high beams was stunningly worth it – I can’t tell you the last time I was so happy with an upgrade.
2/13/24 Update: Lasfit is no longer an Amazon seller. If you search on LED headlight options, there are a bunch of sellers out there getting good reviews. Click here to see them in a new tab.
Now that I am done gushing over the high beam upgrade, the second thing I did was to investigate installing a LED light bar on the truck. That’s really the focus of this post.
I guess it must be the pandemic because there aren’t a lot of custom fit aftermarket options right now but there are still a ton of lighting options using general fit LED light bars – the kind that you normally bolt on to a bumper, roll bar, etc.
My first thought was to mount a light on the bumper but I run a Western plow in the winter. I could have mounted a 26″ bar behind the front lower plastic grill in the bumper or even cut it out for a clear shot but it wasn’t really appealing to me.
Then I got to thinking about how tall the truck was. My 2021 Ram 2500 with the snow package is sitting pretty tall in the air. The top of the cab is about six and a half feet (80-ish inches) off the ground. If I mounted a light bar up there, it would have the elevation to cast a ton of light.
Lighting Options
Over the years, I’ve used a number of inexpensive light bars off Amazon and had while some brands weren’t so great due to leaking water into the LEDs, I’ve had pretty good luck with Nilight. You’ll read mixed reviews of their customer service but fortunately I’ve not needed to work with them.
So, I started looking at NiLights and was particularly interested in their triple row light bars as they can output a ton of light. Honestly, for any of these vendors, take their lumen and wattage claims with a huge grain of salt – there’s a ton of marketing hype. In general, bigger bars and more emitters give you more light – that’s just a rule of thumb to go by.
So, I’ve had light bars up to 12″ wide in the past but they were double row and nothing to spectacular in terms of light output. So, I figured I wanted another Nilight and some width greater than 20″ and they have a bunch of options.
In terms of mounting, I really didn’t want to go drilling into my new truck. On one hand I could mount a light behind the plastic lower grill in the bumper but I really wanted to go high because I do plan to install LED fog lights in the future.
So, one way to mount is to use rubber coated magnetic mounts. They are removable and hold pretty good but they honestly do have limits and will blow off the truck if you don’t think things through carefully. I really wanted to go this route, at least for now as I could remove the light when not needed plus move it around to where I needed light.
Going with magnetic mounts does require you to think about some things. First and foremost, are they strong enough to hold the light in position? What you will find is that they tend to be very strong and pulling a magnet straight off a good metal roof is genuinely hard but that’s not the real issue. You need them to not gradually slide backward and come off at the speeds you plan. In general, the bigger the surface area of the light (width x height).
As I thought about it, I reigned in my length to 26″. I sure debated the 37″ bar but there were two reasons why I went with the shorter bar. First, guys reported that the actual draw of the 26″ Nilight 18025C-A light bar was around 5 amps and that was good because I planned to power the light from the dash mounted cigarette lighter – more on that shortly.
Second, I wanted to lower the risk of the light sliding around. The 26″ Nilight 18025C-A bar comes with three mounting points but I wanted to add more to make sure it didn’t move so I ordered additional set of the Nilight 90035B mounting brackets. That then gave me the ability to mount five of the magnetic bases. I figured that would do the job.
Powering the Nilight 18025C-A Bar
With all of the lighting gear on order, the next thing to consider was the power. Since it was going to be removable, I wanted the power to be mobile as well and not hardwired.
For those of us old enough to remember the old cigarette lighters you know where the name comes from. For those of you wondering what I am talking about, I am talking about the odd looking tubular 12 volt power receptacle in your car or truck. Back in the day, there was a little plug that you pushed in that would cause a little heating element to get red hot and you could light a cigarette or stogie from it … or anything else for that matter – it was like a little red hot space heater or stove element.
In most vehicles, the units can provide 15-20 amps. In a Ram, my understanding is that the center dash unit has a 20 amp fuse. If you are trying to calculate watts, volts x amps = watts so a 20 amp 12 volt circuit can provide 240 watts.
Remember my earlier comment about light bar watt and lumen claims typically being higher than reality? The 26″ bar listing says 540 watts. That is a ton of juice — maybe it’s what it would be if some old incandescent bulb was used but it’s not really drawing that.
There are these really cool switched plugs that have a on/off switch along with a momentary switch and a 10 foot cord. They are well made but I do wish the wire was thicker but it didn’t cause a problem. Note, you can buy these with either the ground (negative) or positive being the momentary switched circuit. I opted for the positive momentary switch because I could just turn the light on for second, let go and it would shut off. If you don’t want it at all, you can just cut off blue momentary wire.
Adding The Mounts To The Nilight 18025C-A
I should point out that I did try just using the original three mounting points that came with the bar and three magnets. During some highway driving tests during the rain I thought it moved some and didn’t think that was secure enough, at least not to my liking. The lights are modular so adding a couple more mounts was easily done.
The first thing I did was to unscrew the end cap from the end without the wire. I removed the end cap and the gasket so I could then slide in two extra M8 hex nut for the two extra mounts I planned.
I removed the cap from the end with no wire, moved the gasket out the way, and slid in two new M8 nuts. I was then careful to make sure the gasket was positioned correctly when I inserted and started the little bolts by hand before using my power screw driver to run them down snug.
In terms of the mounts, I found that their supplied allen/hex socket screws were really a bad idea on their part. You can’t access them easily at all and they limit adjustments so I switched to regular hex head M8 bolts.
With an M8 bolt in place, you can turn the rubberized magnetic mounting disc and tighten or loosen it accordingly. I replaced all of the little hex head socket bolts with hex heads as shown above. I took the little hex socket bolt into my local Ace Hardware and found replacements of the same length.
As with the bolts on the rubber mounts, I replaced the hex sockets on the body too. I honestly have no idea why they opted for sockets vs. head head bolts. The hex heads allow for more rotation and easy access with an open end wrench.
I did apply blue Loc-tite to the bolts going into the rubber pads. In hindsight, I think this might have been overkill. If I ever want to take the pads off, it will take a bit more effort but then again they aren’t going to vibrate loose so easily either.
To make the spacing symmetrical I just moved in X screw heads from each end, centered the mounting block and tightened it down. In my case, I wanted the light to point straight head so I did have to play with that a bit and then match all of the mounts to the same angle.
Here’s the rear view. Once I figured out the position for the light to be straight ahead, I approximated the angle on the others by paying attention to the location of the top of the mount relative to the cooling fin.
Wiring The Nilight 18025C-A
Wiring is very straight forward – red line in the light’s short lead cord to the red line on the power cord. If you want the momentary positive to trip the light also, connect the blue and red cord together. Only do this if you buy the momentary positive version of the cord.
Here’s the switch assembly and it’s cord with the black cord from the light swooping in from the top left. The small black tool is used to trim back the protective outer case on cable assemblies so you can then get to the exposed individual wires. They are cheap and very handy. The alternative is careful slitting with a box cutter/razor.
Red to Red, Black to Black and combine the blue momentary positive to the red positive on the power cord – I just twisted them together and then soldered. Only do this if you made sure to buy the momentary switched positive version of the switch. If you mistakenly bought the negative momentary version you will pop the fuse in the nose of the switch housing because that will be a dead short. That fuse is replaceable by the way.
As far as wiring goes, you can use any of the solderless crimp on connectors or you can just solder the lines together. If I know I will need to take something apart then I will use good crimp on fittings. Otherwise, if I want a slim connection that will last, I use a soldering iron and resin flux core solder.
Be sure to test everything before you close up the circuits. I tested the LED light bar itself before I did anything else.
After soldering, I like to put shrink tubes over each line and then over the bundle to keep moisture out and reduce strain. By the way, if you aren’t familiar with shrink tubing, it shrinks when heated – I prefer to use a heat gun but have also used a lighter in a pinch.
If I want to reinforce it further then I may add on a layer or two of quality 3M electrical tape – overkill I know but I don’t want things to fail easily from flexing or moisture.
I also looked at where the light cord was going to rub on my truck’s roof and added a piece of thick decal vinyl to protect the paint.
So the plug and switches work quite well being in the center dash plug like this. Very easy to reach and turn on or off. When on, the little red LED lights up so you do have an in-cab reminder that the bar is on (trust me, at night, you’ll know it’s on).
You can see how I have the cord run. Again, this is meant to be removable and something I can move around as needed. So yeah. there is a loose cord but it is manageable.
So the light us up top and I run the wire in actually just behind the pillar between the driver and passenger doors in the crew cab. I then run the wire behind the driver’s headrest and down along the center console. Note, there is thick vinyl decal paint protector where the line touches the pain – and about two inches on either side just to play it safe.
So the cord runs under the driver side headrest and then up and out the passenger rear door in the crew cab. I wish there was another 2-3 feet of cord so I could have run it to the floor and around the bottom of my chair but you know, it works. I could have spliced in more wire with pros and cons but I decided to keep it simple.
It really clamps down well on the flat portion of the roof but not in the back with the reinforcing bends. I center the light by eyeball aligning the center mount of the bar with the center roof marker light. The actual bottom of the light bar (not the mounts) is about 81-ish” off the ground. Also, you can’t see it but as mentioned, there is thick 3M Vivid vinyl decal material under the cord.
It’s hard to get the 3M Vivid tape to show up unless you get the angle just right to see the edges. There are two pieces here – one wrapping over the edge of the roof and a second wider piece to protect the paint if the cord is blowing around in the wind much.
Nilight 18025C-A Results
Let’s look at some photos that I took at night and the measures at all based on my laser range finder that I measured before hand from the front of the truck:
These are the stock OEM low beams. Notice how they really limit upward light. The bright oak tree trunk you see slightly left of center is at 23 yards. If you can see the silver tarp in the background, that is at 47 yards.
Ok, mow this one is with the Lasfit LED high beams turned on. The leaf pile in the woods is at 57 yards.
Alright, this is with the low, high and LED light bar running. The light output is amazing. You can’t see it in the photo obviously but the light bar was lighting up a ton of stuff to the left and right as well. The next big tree in the left of the photo is at 31 yards and the swing set is at 44 yards. There’s just a ton of light. This is exactly what I wanted – the Nilight LED bar I bought has a mix of flood and spot emitters to generate this much light.
Low beam only from about 7 yards.
Low and High beam lights at 7 yards. The big shadow is the top left light of my plow.
Low, High and Light Bar at 7 yards.
Summary
First off, it is stunningly bright and casts it very well both forward and to the sides – the breadth of the field of light cast actually surprised me. So, in terms of the shear volume of light it is kicking out and it’s ability to light things up in all directions, it definitely exceeded my expectations.
The switch works remarkably well. The switches have a nice feel and I like that there is a fuse in the switch assembly protecting the truck’s outlet. At no time did the cord feel warm due to excessive draw and I can’t see that it is limiting the brightness of the LEDs any so that worked out just fine.
Next, it seems to stay put – even during rain. Most of my driving has been around town and 35-45mph. I did go on the highway at 65-75mph for 10-15 minutes a few times but not for hours on end. I also have no intention of putting this through a car wash – I really am not sure how it would fare one way or the other.
I would recommend that you keep a towel in your truck to clean the roof before you clamp on the light and also inspect the magnets to make sure they are clear — otherwise you are liable to scratch up the roof or where ever you clamp the light to.
I also decided to keep the light stored in an old duffel bag under my back seat vs. having any risk of it coming off. I put a micro fiber towel in there too – I mainly bagged it to prevent stuff from getting stuck to the magnets and then scratching things up.
This is the light bar, duffel bag and towel that I stash under the rear seat.
The only downside is that I would need to know before hand that I might need the light and install it vs. leaving it attached all the time. I figure in the Spring that I’ll look into installing the flood lights and then decide if I want to do anything after that.
Last photo for now 🙂
So, I am very happy with the result and hope this gives you some ideas as well.

Hi folks, I’ve been doing plunge cuts on Mec-Gar magazine tubes to remove an indent they have to limit rounds. Mec-Gar magzines are high quality and the tubes are hardened high carbon steel. I dulled two uncoated carbide bits that I had bought from either MSC or McMaster before I decided I better try something else.
A quick safety note: For readers unfamiliar with machining, this is an end mill meant to be used in a millling machine in this case. Carbide is interesting in that it is very wear resistant but it is also very brittle. Because of this, the workpiece you are cutting must be very rigidly held in place or the vibrations will tear up the mill and potentially send pieces of carbide flying at you. So, #1 – wear safety glasses. #2 – only do this type of work with a mill. #3 – to be explicit, I would not recommend doing this in a drill press. End of safety brief .
I suspected part of my problem was the heat being generated and adding cutting fluid made for a messy clean up that took longer than I wanted. This made me start researching coated carbide end mills and they get pricey fast.
I decided to check out Amazon because it was a Friday night and I really needed to get some center cutting end mills in ASAP to keep producing magazines.
I ran across a listing a listing for “Speed Tiger ISE Carbide Square End Mills” and started reading. It has an Aluminum Titanium Boron Nitride (AlTiBn) coating that they claimed improved wear resistance and provided better heat resistance as well. Given the number of good reviews they had,I ordered in three to give them a try.
Well, guess what? I am still using my first end mill after 60+ plunge cuts into approximately 18 gauge hardened hgh carbon sheet metal with no lubricant. Make all the jokes you want about dry cutting but it is saving me a bunch of clean up time.
I plan to keep using the first bit and still have two in reserve. Given the very deceent price to performance ratio,I thought I would pass along the report. The following has links to a number of Speed Tiger’s products:
I hope this helps you out.

So I went out to move my wife’s 2000 Camry with a V6 engine. It had been sitting for about a month, it was about 20 degrees outside and, of course, the battery had discharged enough that it wouldn’t turn the car over – I could hear the solenoid click and the starter would just begin to crank and then stop. Great…..
In the old days, I would have wheeled my truck or tractor over with jumper cables, given the battery a bit of a charge and the started the car. Starting some years back, I started using various battery backs with jumper cables – man do they come in handy.
I’ll tell you though, I had a bad experience with four DB Power 1200 battery packs. I wrote about them back in February 2019 and it’s interesting that I can see people searching my blog 2-4 times per month about why their DB Power pack will no longer work. Don’t buy one is all I can tell you.
What was my go-to unit with my wife’s car and in general now? A Noco Genius Boost GB40 1000 amp starter. I’ve used it to start our lawn tractor, my 1996 Land Cruiser, her car once or twice — it’s reliable and it works. I fished it out of another car where it had sat for a month in the cold and it started her car no problem.
This is my GB40 jump starter – I bought it and a storage case to protect it when bouncing around in our vehicles. It has never failed me. I do get it out before a long trip and charge it just to be safe but it’s never empty and it has always worked when I needed it.
I bought the GB40, a storage case and the combination is always with us when we go on trips. They certainly make other models as well so you can pick the combination of size and price that works for you. For our regular cars and trucks – the GB40 has worked just fine. I definitely recommend the Noco products.
