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.
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.

A fellow asked me the other day how I can run my shop Ingersoll Rand (IR) 2340 compressor, which is an oil lubricated 60-gallon compressor, in the winter in my unheated shop. The reason he asked is that as the compressor gets colder and colder, the oil gets thicker and thicker. The end result is that many compressors will not even start below 32F (0C) – the motor tries to spin the air pump, there’s too much resistance, the motor draws too many watts and trips the breaker… or burns out the electric motor. Because of this, many air compressor companies will tell you not to run your compressor when it’s below freezing. I’m going to tell you what I do and you can decide what works for you.
I’m sure you’re wondering why I just said that last part and it’s because I will not be liable for any problems you may have. I’m going to tell you what I do, or have done, and then you need to do some research, conduct some tests and decide what works for you.
Run synthetic oil – not conventional oil
The first thing I will tell you is to run a good synthetic compressor oil and not the basic Petroleum 30 weight oil that probably came with your compressor. I use Ingersoll Rand’s All Season Select Lubricant because I bought it in bulk a few years back. It’s pretty good but you do have other options as well. Note, it does need a crank case heater to not trip the 30A breaker my 2340 is connected to when it gets really cold (down in the teens or lower).
Another option is moving to the thinner 10W30 Mobil 1 Full Synthetic engine oil in your compressor. I did this some years back with a Husky compressor that I eventually replaced with the bigger IR unit I have today. Some guys go even thinner to 5W30 but I have a hard time recommending really thin stuff like 0W-whatever but there are definitely guys out there who do it on smaller compressors – I’m just saying that I would not do so personally. Note, we are talking about full synthetic oils here and not regular engine oil.
Regularly change your oil
If you have never changed your oil or don’t follow the maintenance schedule of your compressor and oil combination, you really need to. Contaminants and what have you can make it harder for the motor to turn the pump over – even in good weather let alone cold weather.
Run heating pads on your pump
A trick I learned some years ago for stationary compressors is to put one or two of the small oil pan heaters on the pump alongside the oil reservoir. I run one Kat’s 24025 25 watt heating elements that measure 1×5″ on each side of my pump. No more tripped breakers for me.
Be sure to keep your tank drained
Condensation is more of a problem in the winter. The relatively warm moist air can condense on the walls of your tank and then go through your air lines causing your tools to freeze up. It usually happens when the weather really sucks and you need the tools the worst.
Start With No Load
One trick to try in a bind is to start with little to no load. In other words, empty the tank so the motor isn’t fighting both thicker cold lubricant and pressure in the line as well.
The thought process is that your bleed off valve that empties the line from the pump to the tank and to the pressure switch might be frozen up from moisture or bad/failing. For example, the switch on my IR 2340LF-V is a real cheaply made POS – I’m miffed about the quality and am not going to mince words about it. I’ve replaced it once already and as of this writing it’s starting to fail again about a year later after the last time and I already have a replacement on hand.
Also, one trick I learned from an old timer is to add more line or a reservoir between the pump and the tank so the motor can get a running start before it encounters resistance. Here’s a post I did some time back about that.
Conclusion
You definitely can run an oil lubricated compressor in the cold weather. It just takes a little planning and preparation is all. It’s my hope that the above gives you some food for thought and you can then research what will work best for you. You’ll notice that if you do some Googling around, you’re in good company with a ton of other folks trying to figure out what to do as well.
I hope this post helps you out.

Folks, I’ve used Harbor Freight’s Central Pneumatic 2-1/2 gallon (10 liter) paint pots (HF Item 66839) for years to pressure cast grips. You may know them as “paint pots”, “pressure pots” – they are the same thing. I read fear-mongering stories on the Internet where folks are scared of them blowing up. You know what? They’re safe as long as you stay within their pressure rating and I know what I’m talking about. I’ve used my tanks through thousands of duty cycles at 60 PSI with no major problems.
There is a headache though – the cheap gaskets the tanks come with either don’t last or are a bear to seal. It used to be you had to make your own replacement gaskets or try to repair what you had but now there is an awesome ready-to-go quality gasket you can buy.
How are they better? They are thicker and the durometer (firmness) of the gasket is such that there is a bit of give to get a really good seal. The gasket measures 10-5/16″ for the outside diameter and 9-5/16″ for the inside diameter. It’s also a 1/4″ thick which is great and the dogs (the bolts on top that secure the lid) have enough adjustment to accommodate this thicker gasket.
To cut to the chase, these units fit my pressure tanks perfectly. No more gluing, cutting, etc. These work right out of the box and are way, way better. They also fit a number of other thanks including:
TCP GLOBAL Brand 2.5 Gallon Pressure Pot Tanks Systems. Part# PT8310, PT8312 and PT8318
Binks or Devilbiss Brand 2.7 Gallon Paint Pressure Pot Tank Systems that use the Devilbiss Part# PT-33 Gasket. Binks Tank Part# 83C-210, 83C-220 and 83C-221
Other brands of tanks as well – many are made by the same Chinese factories and use the same size gasket.
Installation is a breeze
Literally, pull the old gasket out and push this new one in place. I did not need to do any trimming. When I put the lid back on the tank, I did have to back off the toggle bolts in the dogs (clamps) so that they could pass over the edge of the lid given it’s new taller height but that was literally just backing the off a 1/4″ more or so. Then when I turned the bolts down, the clamping pressure fully seated the gasket and the job was done. I spent more time taking the pictures than I did replacing the gasket and adjusting the bolts!!
These TCP Global replacement gaskets are awesome. The seal works wonderfully and I can just tighten the lid down by hand now – no more wrenching. If you have a tank these gaskets will fit, I highly recommend them.
August 24, 2024 Update: They have held up great. I am now using them in all four of my pressure pots.
March 6, 2022 Update: These are still working great. I’ve slowly replaced most of my original HF gaskets with these and have no problems to report.
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.

Everyone is trying to save money these days and that includes me. When you start talking about quality carbide end mills and cobalt drills, the costs rack up fast but there are options for you to save money and I’ll make this short and sweet.
To be clear, these folks did not pay me or even know I was going to do this blog post. I’m not getting a dime from them.
I needed to buy a 3/4″ reduced shank cobalt drill bit. These things are usually around $40-50/ea and I was able to get a nicely made Qualtech from Drills and Cutters for $32.91 out the door. I use this bit for drilling out the top of my AK-12 grips and the glass reinforced polymer shreds HSS bits so discount Silver & Deming bits don’t last. Spending the money for a quality bit made from cobalt makes a ton of sense because it will do hundreds of holes before it needs to be sharpened.
So, Drills and Cutters is a web store that you can buy from and they may have the manufacturer ship direct to you. I have found their pricing and shipping speeds very good.
They sell drill bits, taps & dies, cutters & saws, reamers, end mills, carbide burrs, annual cutters and more.
The second group I want to share with you is EndMillDiscount.com. Carbide is not cheap and “cheap” carbide tooling does not hold up. I go through a fair number of carbide end mills and carbide spotting/centering drills each year. When you need to drill hardened steel, there are situations where you simply need the hardness to cut. So, I needed to order in more 1/4″ bits and started shopping around. With the word “Discount” in the site’s name I was a little nervous but they had *really* good prices and I couldn’t find any negative reviews so I took the plunge.
I ordered 4 of the HTC 4-flute 1/4″ diameter end mills at $7.15/ea and 2 of the SwiftCarb Spotting/Centering drills at $16.98/ea and shipping was only $10.51. Wow, in just a few days the end mills arrived drop shipped from HTC and then the drills arrived drop shipped from SwiftCarb. I was very impressed.
End Mill Discount sells end mills, drills, micro tools, cutters, cobalt tools, carbide burrs and more.
I definitely plan on buying from them again. Visit them at:

In the last post I told you about removing the rust from the old Ridgid pipe wrench using a solution of apple cider and Prep-N-Ethc. Now we’ll go over painting it. I considered three options – using a durable bake on weapons paint, a spray on epoxy paint or a basic spray paint. I went with the latter simply to save money. It just so happened that I had cans of Fusion All-In-One Gloss Red Pepper and Satin Black Krylon in stock. All-in-one meaning it contained both the primer and the paint.
What is Krylon?
Krylon is an acrylic laquer and not an enamel. In case you are wondering about the unique name, it comes from the founder’s first two letters of his last name – Krester – and that he was so impressed by Dupont’s discovery of nylon that he dropped the “n” and called his paint Krylon. This was a marketing move because he’d developed the basic formula in 1947 and nylon was introduced shortly after.
I like Krylon because it dries fast. I hate waiting for Rustoleum to dry and that pushes me in the direction of Krylon. With that said, Rustoleum’s enamel paint tends to be more durable. If I had it in stock, I would have used Rustoleum and baked it on.
Applying The Krylon
I took the wrench, disassembled it again and sprayed everything down again with brake cleaner to make sure there wasn’t any oil. A side benefit of acid rust removal is that it does acid etching of the surface as well creating little pockets/surface imperfection all over that give an excellent surface for finishes to adhere to.
When spray painting, you need to be patient. You build up to the final color you want by spraying successive coats of paint. Follow the directions for drying time per coat and the maximum time to wait to apply the next coat.
Because I acid etched the surface, I didn’t apply a primer plus Krylon’s Fusion series claims to have some primer in it. I noticed on the can they still recommended primer for a bare metal but I skipped that. I typically waited 15-20 minutes between light coats based on the instructions on the can. Light coats reduces the risk of runs and making a mess.
Be sure to let the paint have plenty of time to set before you turn it over. Either wait until just before the maximum time before next coats or you will need to wait until the first side fully cures. I would rather try and do it together to get the best adhesion that I can. If it fully cures then you either get a less than ideal bond or you have to scuff it. Some folks will hang their parts to avoid some of this.
So, I put the parts in my curing oven for a couple of hours at 175F to help stuff dry fully and let it sit overnight before reassembly. With enamel, a lot of folks say that baking helps. I don’t think it makes a big difference with Krylon but I do know that it pays to let parts have the full time to cure based on the instructions on the can. If they say 24 hours, give it 24 hours. I’ve ruined a ton of paint jobs being in a rush.
So here is the refinished wrench:
Conclusion
Well, it was interesting to learn about Ridgid and to bring some color back to the old wrench. I’ve already used this to tighten a pipe since I tool the photo. The paint did come right off the jaw as I knew it would but I’ll definitely be using it more in the future and remembering my dad and grandpa who passed it down.

Like so many of my stories, this one begins as so “One day I was in my shop and ran across and old rusty tool that was still functional”. Let’s start with a bit of backstory.
My grandfather immigrated from Quebec along with his brother to the Boston area to improve their lot in life. They’d grown up on a farm near Compton, Quebec, and somewhere along the line had picked up the skills necessary to service heavy machinery. He’d tell my dad stories of working on various machines who then relayed some of them to me.
My grandfather had a family, including by dad of course, somewhere near Rockport and eventually bought a farm in Derry, NH, sometime in the late 1930s or early 1940s where he raised dairy cattle, grew hay and what not. Along the way he amassed quite a few tools that then passed on to my dad.
One of these tools was a rusty 18″ pipe wrench that I recall my dad using on a number of occasions and when my dad passed away, I got the tools, including this old wrench.
So, I’m in my shop moving stuff and uncover this big 18″ pipe wrench that I then took a lot closer look at. Interestingly enough, it was made by Ridgid.
Ridgid and the 18″ Pipe Wrench
For years I thought Ridgid was a made-up Home Depot house brand. Actually, it was founded in 1923 in North Ridgeville, Ohio, and moved to Elyria, Ohio, in 1943. What got them started was the invention of the modern pipe wrench. In 1966 it was bought by Emerson Electric and today it sells a lot of different tools including hand tools they make, power tools by Techtronic Industries of Hong Kong and Wet Dry vacs made by Emerson.
Now if you read the caption of the photo above, the 1727623 patent was in 1929 and 2051755 filed in 1936. That patent was actually split into two and an additional patent 2076830 was filed in 1937. I’m going to go out on a limb and bet that wrench was made somewhere between 1929 and 1937. The compression spring in the wrench is a leaf design and not conical so that does put it prior to 1937 patent.
In reading, guys report the markings as not being very reliable and company records incomplete so the above is really a best guess but it does basically align with when my grandfather would have been buying tools.
So I had a decision to make – leave it alone and let it rust or clean it and apply paint. Well, it’s not like these wrenches are rare collector pieces and this was a tool I would use going forward – seriously, other than being rusty it was good as new.
Removing the Rust
I considered three options – abrasive, electrolytic or acid. The rust was actually pretty light and I opted to go with acid – notably a combination of apple cider and phosphoric acid.
The first step was to spray down the wrench with brake cleaner liberally to get rid of oils. Next, I put a wire brush in my hand drill and removed all of the loose rust and dirt from the wrench body, nut and jaw.
The acid bath was a gallon of grocery store bought apple cider vinegar plus about a quart of Prep-N-Etch phosphoric acid. Apple cider alone would do the job but I was re-using apple cider and I wanted to make sure there was enough acid to do the job.
Now a trick to really get things done is to heat up the apple cider bath and get it warm – you don’t need to boil it. I don’t bother with a thermometer for this – just hot to the touch. The reason why is that heating up a solution speeds up the chemical reaction. If it’s cooler then it just takes longer and if it is boiling off then you are losing liquid needlessly.
Please remember something – do this in a well ventilated area or outdoors or the condensation will cause exposed steel to rust. It’s a very weak acid solution and while the vapors aren’t something you should be breathing, I would be more worried about causing rust if I were you.
Before I put the wrench parts in the warm/hot acid bath, I really hosed them down with brake cleaner one more time while wearing nitrile gloves. The reason for the gloves was mainly to keep oils from my skin from contaminating the otherwise clean surface. Oil will block the acid. The hot bath will remove some oil but it is contaminated at that point and must be discarded.
I checked it every few minutes and when all the rust was gone, I pulled it out, hosed it down liberally with water and then used WD40 to displace the water and reduce the odds of rusting. This is what WD40 was meant to do – water displacement formula 40.

Growing up, my dad has this big rusty vise on his work bench and we’d use it for all kinds of stuff ranging from holding mower blades and axes during sharpening to bending metal for brackets and so forth. I knew it came from my grandfather’s farm in New Hampshire but not much else., When my parents moved near us, my dad brought the vise with him and installed it on a tool bench in their new garage.
Life can be harsh. I have a lot of good memories about my parents but nothing really prepares you for when they pass away. I was close to my dad and to this day, when I use one of his old tools, it makes me feel good – kind of like he’s still here and happy to see me using something of his – hopefully the right way.
At any rate, when we had to sell their house and clean stuff out, I snagged the big old vise and stuck it on the floor in the corner of my shop and really didn’t think much about it for almost five years. One day I started thinking about installing a second vise in my shop near another area where I do a lot of work that requires both work holding and a vise that can withstand 50-100 ft/lbs of torque. I figured I had two options – I have a 6″ Harbor Freight unit somewhere buried in my shop that I could dig out or I could go find my dad’s and take a closer look at it.
So. I dug out the old vise from under a work bench and blew off a ton of dust and dirt. The first thing that I noticed was that it weighed a ton and the second was that it was remarkably beefy and actually in really good shape other than surface rust. The action moved fairly well albeit a little gritty. Everything felt fairly tight meaning nothing seemed to be bent or broken. Last but not least, other than missing the handle on the locking nut, everything seemed to be there.
Where did Samson vises come from?
I did some searching on the web and found mention that Samson vises were sold by Sears from about 1908 to 1939 based on searching for “Samson Machinists” on ancestry.com. This page is from a 1923 Sears catalog and was copied from Vintagemachinery.org:
There it is down in the lower-left – 99N5263. A 3-1/2″ jaw width with a 5″ opening, weight was 37 pounds and cost a whopping $9.30!! Wow! Now, when my grandpa actually bought it, I have no idea. If my dad knew, he never said or I don’t recall – at this point, I’m really not sure.
By the way, in the catalog ad above, look at the weight of the 5266 5″ vise – 93 pounds! That would be a fun one to find. It must be enormous – I’ll have to keep my eye out for one 🙂
By the way, I couldn’t find a definitive answer about who made the Samson vises for Sears. Some people thought it was Reed but I haven’t confirmed that. If you search on Reed Vises, you will see some similar designs but I did not see an exact match. I emailed both Reed and Yost to see if they can share any insights. If I find out, I’ll update this post.
8/25/2020 Update: I got a very nice email from James about Samson vises based on some research he did: “Samson Vises were the Sears house brand before Craftsman took over in 1927. Samson Vises were made by Rock Island Vise Company for Sears and Roebuck out of Rock Island, Illinois.”
Restoring the old vise for regular use
Other than quite a bit of surface rust, it was really in very shape and I decided to use the old vise. The next thing I had to decide was what to do with the finish – it was rusty my whole life so I thought about just oiling the rust and sealing it. Another part wanted to fix it up. I honestly thought about it for a few days because I couldn’t do anything right away. In the end, I decided to refinish it. From what I could tell the vises were originally black and either partially or fully painted. My vise had zero paint on it anywhere.
Note: I am not doing a 100% overhaul to make it look like when it shipped from Sears. I wanted to clean it up some have it be functional. I just want to be clear in case any purists take issue with my use of the term “restoration”.
So, the first step was to disassemble the vise both to make sure it was indeed salvageable and also to clean everything. The weather wasn’t cooperating so you’ll some photos were taken indoors and some outdoors so bear with me.
Conclusion
So the vise is back in use. Every time I use it, I feel good about it and hope my dad approves.
