Thomas’ AMD-65 With Our Blue Grips

Hi folks, Thomas shared this cool photo of our blue AMD-65 grips on his rifle. It looks pretty cool!!

A big shot out to Thomas for sending me these. His rifle is definitely cool – note the riser he installed on the buttstock to make it more comfortable also – nice touch!

Fixing the Water Inlet Valve on a KitchenAid KRMF606ESS01 Refrigerator

Well, when I was little it seemed like fridges (“refrigerators” for people who prefer the full word) lasted an eternity. When we bought this KitchenAid KRMF606ESS01, I thought I was buying a top of the line quality fridge, but that’s no longer the case – appliance manufacturers don’t necessarily want them to laste forever because that means no more sales to a given customer.

A year after the warranty the ice maker stopped working and the service person whom I trust told me it would cost a considerable amount of money to replace the circuit board. So, strike #1 against the KitchenAid. Despite being “stainless”, the shell of the fridge rusts. Strike #2. Strike #3 is the topic of today’s blog post. The water inlet valve failed and leaked water all over our wood floor.

Let me set the stage – I went through the kitchen to my shop and when I came back in I saw wet footprints – my foot prints – from the floormat in front of the fridge to my shop door. ARGH! I was hoping maybe someone spilled water and didn’t clean things up so I removed the mat, mopped up the water with a towel and watched new water slowly emerge from under the fridge. Crap. I immediately wondered about the water lines on and in the fridge. The supply line was copper tube and it had looked great the last time I pulled out the fridge so I doubted it was that but I couldn’t ignore it either or it would ruin our real wood plank floor.

Turning off the water

Most fridge installers put a vampire tap on a water line to get the supply needed. In my case, I knew there was a tap under the house. We have a crawl space that isn’t bad compared to some that look like they are a scene from a horror movie but being a pretty big guy with a sore back I have to fold myself in half and do a crab shuffle over to where it is about 50-60 feet from the entrance. Short translation – it’s doable but I swore the whole way over to it.

See that far center column in the dark? Yeah, I was heading just to the right of that and swearing the whole time. It was way easier getting under there 25 years ago.
I don’t know if these things have a formal name – I’ve always heard them called “vampire taps”. They re put on copper supply like with a rubber gasket between the part of the saddle with the valve and the pipe. The two halves of the clamp are screwed together and then the handle is screwed down until the sharp end of the valve pierces the relatively soft copper. You then back the valve off (meaning turn it counter-clockwise) and water begins to flow through the supply line. So, with this in mind, I needed to close the valve which means turning the small handle you see clockwise until it stops thus closing the valve. I’ve needed pliers in the past to deal with hard turning valves and these things are also known to leak when you try to close them. I got lucky – it both turned easy and it shut the water off entirely just the way it should.

Confirming it was the inlet valve

In reading, there are a few ways these inlet valves fail – they can leak water on the floor but still work and dispense water, not leak but dispense water very slowly, or don’t work at all. I was 90% sure it was the valve given past experience with other fridges so the first thing I did was to pull out the unit.

If you have never pulled your fridge out before, let’s start here. See the plastic facia/cover below the door? That is just for looks and pulls off but you need to open the lower freezer door to do so. Note the rust on the “stainless” steel skin above and to the right of the KitchenAid logo. “Stainless” is a generic term and really the resistance to corrosion is dependent on the alloy used. Whirlpool/KitchenAid went with a cheaper alloy to save money so it’s not very “stainless” over time.
By pulling the freezer door open, the entire plastic covering is exposed and it literally just pulls forward – no screws or freaky little clips to deal with. They know folks will need to pull this off periodically (or they should) to clean the condenser coils under the unit. So, pull it off and completely remove it.
The fridge has four wheels to allow you to move it but if these small levelers are in use it will not want to move. Take a small wrench and turn the head of the bolt to retract the leveler on each side. The fridge will now pull forward. Peek in back to make sure you have enough water line to do so. The water supply line and the power cord will limit how far you can pull the unit out until you disconnect them – if you even need to. I never unplugged my fridge while working on it for example.
There was a real small chance that the supply line was loose so I tightened it just a tad and then hand my wife watch the valve for leaks as I went back under the house to turn the tap back on. It’s way easier and cleaner to do it with two people. So, I turned it on and she called down that water was going on the floor and I shut it off. The water started right under the valve and everything else was dry … my money was on the inlet valve was the culprit and it was.

Okay, the water inlet valve is a small electricslly controlled valve that is turned on and off by either the ice maker (that no longer works) or a person wanting cold water from the dispenser pushing their cup against the on-off switch. The valve body is made of plastic and that is what failed. The only saving grace is that the engineers put it at the back of the fridge and it is very easy to access and change – literally a 5-10 minute job. You can easily buy one online without spending a fortune.

To order parts for your fridge, you need to know the exact model number – in my case it was a KRMF606ESS01. You can find this info inside your fridge – in my case this sticker was on the inside top left of the unit facing down hence the camera angle is looking up.

I spent some time searching on Kitchen aid KRMF606ES01 water valve and found out that my fridge has two – one at the inlet (that I needed) and one inside that I did not so make sure you order the right part. The valve part number I needed was W10394076.

Direct from KitchenAid I could get the part for over $95.49. No, Whirlpool, I didn’t feel like spending a fortune by ordering it direct. I kept on searching and found it in the $70s then the $50s and then hopped over to Amazon and found it for $27.99 with free Prime shipping. It got great reviews and I ordered it on Saturday with delivery on Monday. Guess what – it was the exact same valve. Strike #4 for KitchenAid by the way.

I’m jumping the gun a bit but this is the sticker on the original that I removed from the fridge. Note the maker is Robertshaw and their part number was K-78282 with Whirlpool’s W1039476 part number indicated.
Same maker – Robertshaw – slightly different part number K-78282-AM — the suffix probably denotes some relatively minor changes. No Whirlpool part number on and and no ghastly markup either. It is an exact match otherwise.

Replacing the valve

First, make sure the water supply is turned off and have a container you can set the supply line in just in case it drops. I’ll step through this with photos:

get the the fiberboard back cover out of the way by removing the screws around the edges. Doing this gives you easier access and you can make sure there are no drips when you are done.
Always compare new and old parts to make sure they match. I have been burned so many times over the years that this comparison is automatic for me now – don’t assume anything.
I’d recommend moving connections one by one. Take one off the old valve and put them on the new one. Then again, you have three very different connections so mixing them up would be next to impossible. Do note the orientation of the electric connection and keep it the same. In this case, I am using the adjustable wrench to hold the steel bracket and a flare nut wrench to loosen the water supply line. Never use an adjustable wrench on flare nuts – if the jaws give you can round over the nut so at least use a fixed wrench or better yet a flare nut wrench.
The waterline in the bottom is connected via a “push-to-connect” or “push connect” ,fitting. Push the blue collar in towards the valve body while pulling the outlet water line away and it will come right out. Note where the white electrical wire is for reference. Looking at the valve from the back, it is on the left side.
This is everything moved to the new valve. I then put it in place and secured it with the original screws. Again, note where the white wire is at. I didn’t want to find out if it mattered which side was connected so I just followed the same wiring orientation on the new valve, Also, use the adjustable wrench to hold the valve body while tightening the flare nut.

And with the new valve unit installed and my wife watching everything, I headed back down into the crawl space and turned the water on. No leaks. She tried the water dispenser and it was actually putting out a larger volume of water also – our jet had always been on the anemic side.

So, I waited while she filled a few big cups of water and threw them out to purge the lines. She also didn’t see any leaks so I headed back up after a few minutes hoping my crawl space work was done … and it was.

I looked for myself and it was definitely a much stronger jet of water – it had never moved that much water.
After a half hour of careful monitoring for leaks, I sealed it back up. I then waited a few hours and double checked by moving it forward a tad and checking around underneath with a flashlight and no leaks so I slid it back in place. When you slide it back, make sure the power cord and water supply line do not get caught on anything.

With the fridge back in place, use the levelers if you need to – I don’t actually.

I didn’t get photos but the last thing I did was to use a long brush made for cleaning condenser coils to do just that. As lint and dust build up on the condenser it becomes less efficient, the fridge runs more and your electric bill is higher. The lint and dust there by the way because of an electric fan that is running underneath to help cool things off.

The last step is to open the lower freezer door and push the plastic cover back on the bottom. Done.

Summary

A week later and it is still running great. I hoped that the ice maker might start working again but no luck there. We bought am Aglucky counter top ice maker a few years ago that we’ve been very happy with.

I paid a premium for a supposed top-of-the line KitchenAid fridge and I don’t think the same level of quality is there. We have a Samsung fridge downstairs that has been flawless for us. When we replace this main fridge in the kitchen it may very well be a Samsung but it will not be a KitchenAid.

In the mean time, if you are having problems with your water inlet valve, I hope this helps you solve your problems and save some money.

3/2/24 Update: The new valve is still working great. We noticed we have more flow also – glasses fill faster. So, if you want to save some money, it’s an easy DIY repair that valve is still only $27.99 off Amazon.

Use Super Glue to Seal and Stabilize Wood

Have you ever had wood that is in tough shape or is too soft to work with? A quick fix is to use super glue on the wood and let it set. Let’s talk about this for a minute.

Super glue is actually a family of glues called “Cyanoacrylates“. The patent for the original product goes back to 1942 when BF Goodrich was looking for a clear adhesive for gun sights in WWII. As they say, the rest is history.

There are many different brands and types of super glue. For the brand, I stick with name brand and usually get biggger bottles from firms such as Bob Smith Inc (BSI), Starbond, Loctite, Gorilla Glue, etc. With the no-name generics, you never quite know what is really in the formula or how good it is.

The glues are available in different viscocities/thicknesses also ranging from Super thin to normal, to gel, etc. For our purposes, we want th thinnest glue we can buy. Why? Because it will really soak into the wood and follow all of the little cracks that are opening, seal and reinforce them.

So, when I say I am using it to seal and stabilize, what do I mean? To seal means that water can’t get in. To stabilize means it is soaking into the soft wood, filling small cracks and when it dries it will harden the treated area. I’ve used this to fill small cracks in wood rifle stocks, knife handles, tools, furniture – anything with wood.

Super Glue is good for stabilizing but not filling an area. If you need to build something up, fill in a gap, or rebuild an area, then use an epoxy.

These slats bench slats had chunks of wood missing that I built up using epoxy. I sanded them down flush and then applied two coats of thin CA glue to the surrounding wood to stabilize it. I then used an opaqe wood deck stain and you couldn’t even see the repairs.

I apply several coats. The first one I apply quite a bit of glue and just let it keep soaking in. You’ll see it following cracks and what not. Once I get the surface soaked, I stop and let it cure. I typically wil do 2-3 coats/applications depending on how bad the wood looks. Usually after the second coat everything is sealed stabilized.

As it cures you will see a light white-ish smoke. Don’t get the fumes in your eyes or it really stings – you don’t want to breath them either. Small pieces like a knife handle aren’t too bad. For pieces bigger than that, all of the fumes really make this something you either want to do outside or in a room with really good ventilation.

Let me show you a few photos form a recent project where I needed ro reinforce the area around a wood gate latch. The wood was in really tough shape and I didn’t have the time to go to buy the lumber, cut it and make a new one. I keep thin super glue in stock at all times for all kinds of projects so I just did that

Starbond makes good CA glues from my experience. I’ve used a number of their forumlas and been happy with the results. As you can see, the wood is in tough shape. It probably should be replaced but I don’t have the time.
I let gravity work with me and apply the glue to the top of the wood and let it soak into the end grain. I could see it going down the board and the wood looking wet where it travelled. You’ll use a fair amount of glue doing this, I went across the entire top of that board and watched for the glue to penetrate – in this case I wanted it down near the screws. When it the glue cures, the stabilized wood will still a bit darker than the surrounding untreated areas.
This board was in really tough shape. It soaked in a lot of glue and I kept adding it until I saw it saw it in that big crack.
Here, the CA can help seal the top and stop the small cracks but there is no way it can fill the big crack.

Summary

You can definitely use thin super glue to seal and stabilize wood. Use a reputable brand and work in a well ventilated area. What I have been using the most lately is Starbond and they have a full lineup – click here to see them on Amazon.

We are Labelling Our Custom 10mm Mags For Rock Island Armory A2 HC Pistols

We’ve made and sold hundreds of our custom magazines for the Rock Island Armory (RIA) A2 HC (High Cap) 10mm & .40 S&W pistols. These pistols are based on the Para design with a staggereed magazines that hold 15 rounds normally. Our mags hold 16 and are slightly longer.

The main reason I am writing this post is that our magazines use tubes originally made for the Para P14 pistol chambered in .45 ACP so they are stamped “P14-45” and there hasn’t been an elegant way to change that – the tubes are hardened and trying to stamp something else in would be messy. A laser engraver is an option but I don’t have one.

I was working on another project involving “permanent” labels – these are labels that have a really strong adhesive and last far better than regular labels. “Permanent” is a marketing term though – they can wear off, etc.

At any rate, it dawned on me that with the right size, I could have a clear thick vinyl label made with white ink that has “10mm & .40 S&W” written on it and that’s just what I did. You’ll find these on the baseplates going forward

So, yes, our tubes still have P14-.45 on them but now they have the correct chambering on the decal on the baseplate.

This is a normal baseplate with the label.
This is a baseplate that has been riveted closed because the tube has been blocked to 10 rounds. We also make 15 round limited mags. They are for folks who live in an area that has magazine limits.

By the way, if you ever want to confirm whether one of my mags is for 10mm or .40 S&W, the gap between the front feed lips will be between .370 and .390.

If you are interested in buying a magazine, please click here to go to our store. All of our magazines are converted, tuned and tested by hand one at a time.

Latex-ite UltraShield Driveway Sealer Has Limits – It Seals But Does Not Repair

My wife and I wanted to seal our 160 foot long x 12 foot wide driveway in 2022. My first thought was to use a service but they were sold out for the season by the time we asked so we decided to try and do it ourselves.

What I found out is that the old days of buying some liquid tar / oil based product are gone. You have to buy all these different products that are based on latex of some other chemical. You need one thing to seal holes, another for big cracks and the sealant. Okay, we have a big driveway and it is beat to hell, falling apart and really ought to be replace but we couldn’t afford it. So, what did we do? We took a gamble and the results are so-so but I learned a lot and want to share them because I bet they will help you regardless of brand or product you are using.

Getting Started

I did the math and bought a bunch of pails of Latex-ite UltraShield. What I did was I took the length of the asphalt portion of my driveway x the average width in feet. I then divided this by their average coverage ratio: 160×12/200=9.6 pails. I think I actually bought 10 pails at my local Home Depot but ecause my driveway was in such tough shape, I wound up actually using 14.25 pails for two coats.

There were areas where the old asphalt had crumbled and disappeared. I bought bags of Quickrete asphalt patch to fill in these places. I first broke out the old material into rough rectangles and dug down another inch.
This is the result – I used a tamper to beat it down as best I could and then sprinkled the top with sand so it wasn’t so sticky.
Our driveway was in tough shape – we knew that but were hoping to extend the life a few years. After we filled in the big holes – one of which you can see part way down.
My friend John had a good suggestion – heat up old pieces of asphalt with a ground torch and beat them into holes. So I did that in some places where missing asphalt caused a gap.
I read the Late-Ite Ultra Shield directions, watched several videos and new surface prep would be key. I burned off grasses and moss with the ground torch, sholved the grass back off the edge, blew it clear with a blower and then washed it – literally. That is my pressure washer – I went down the whole driveway and first applied Purple Power to clean and degrease it and then another pass with just water in the pressure washer to get rid of the cleaner. It was so clean you could eat off it … time would tell me I got it that clean in most places but not all.
The day before I flipped them so the solids would break free of the bottom and go towards the lid.
The recommend applying the sealer by going left and right with a squeegee – overlapping the last pass and pressing it into the asphalt.
When I got done it looked amazing. You can see all the still wet sealant in the cracks.
I then applied a second coat. The first coat used up each pail real fast due to the cracks. The second coat went much faster and each pail went further. By the time I was done, I had used 14-1/4 pails of sealant and the coverage comes out to about 134 sq ft/gallon if I am doing the math right.

The Results Six Months Later After Winter

I had a really bad experience once with a wood deck repair chemical that claimed to fix anything that looked awesome in the summer but then the wind literally blew it off in sheets during the winter. The deck sealer had glowing reviews that first summer and then got absolutely smalled with one and two star reviews at Lowest after the first Winter. My point is that I have been sitting on a ton of photos and stuff since last fall to see how it would actually hold up before I wrote this post.

The first thing I want to be clear about in fairness to Latex-ite is that they tell you over and over it is a sealant and will not fill big cracks. Well, even though I searched a ton, I ignored that. I shouldn’t have.

Latex-ite is basically a glorified black paint that dries and hardens on clean solid asphalt to seal it. Well, it looks brownish as you are applying it but it turns a nice rich black as it dries and cures.

One thing I learned is that where it can’t get a good grip, it peels up so a oily, dusty or dirty surface will not work. I tried to do my mother-in-law’s little short driveway in a rush and didn’t get it pristinely clean in all places so I can tell you it doesn’t stick plus I had a few on our driveway as well.

You also need to squeegee it in place to force it into cracks, crevices and pores but if applied too thick, such as in the tons of larger cracks on my driveway, it will crack, break down and otherwise slowly disappear.

In short, it is just a sealer and gives you a good looking new black coloring on your asphalt. It really is not a filler, glue or anything else in terms of fixing things.

The following photos show the difference between mid-September 2022 and March 2023:

Most cracks over 1/4″ do not have any visible selant in them. The black sealant is on most of the larger pieces – the brown tracks are where we drive and yes, the area is very wet every spring.
This view is bakc towards our house. The family who had the home built in the 70s had a concrete driveway poured closer to the house and asphalt from a certain point to the road. It was probably a cost savings move and the asphalt is neither very thick nor sitting on a very well prepared bed.
You can see how the sealant is breaking down into flakess and separating.
This is by one edge – it tells you that I didn’t get the drive way as clean as I thought in all places. Again, the sealer can’t bond to dirt so it will curl or float there and rapidly break down as you drive over it.

Summary

What I want to take from the blog post are some key lessons learned:

These new drive way finishes – all of them that no longer have oil/petroleum products in them – have limits so carefully read their instructions, application notes and reviews by others. If they say they can’t do something then respect that. My biggest regret in hindsight was trying to use the sealer to fill the cracks – it can’t and the maker said so.

Surface prep is key followed by applying two good coats with a squeegee. The Quickrete patch held up fairly well. The sealer helped keep it from falling apart during freeze-thaw cycles, something I have experienced multiple times in the past.

John’s idea of heating up asphalt pieces and beating them in place worked just fine – no surprises there.

What are my thoughts on Latex-ite UltraShield? Well, to be completely fair to them, the product performed as they said it would. If my driveway wasn’t in such tough shape, I bet it would have held up better. In places where it could get a firm grip on the asphalt it still looks good.

Am I going to use it again if I try to reseal the whole drive again? Maybe not. I would really like to find something that is more flexible given my driveway’s shifting nature but first I need to apply crack filler before doing anything else.

Does it look better than before I started all this? Yes, I think it does. Not as good as I would like but it is better. At best, I am playing a delaying game. We will need to replace that driveway at some point but if I can get another 5-10 years out of it then great.

Let me stress this one more time – regardless of brand or product, unless your driveway sealer or finish says it can fill cracks and gaps the sizes your driveway has, you will need to take care of them first.

I hope this gives you some food for thought.

Understanding how an automatic folding knife works – Kershaw Launch 1 Disassembly and Re-Assembly

In the last post, I showed you a bunch of photos of the Kershaw Launch models 1 and 13. In this post, I am going to take the Launch 1 apart so you can see what it looks like inside. So, let’s get into it.

Tools Required

You will need #6 and #8 Torx bits. Something to pry the blade up and tweezers might help. For me, I have a large Strebito tool kit with a ton of precision bits, handles, tweezers and pry bars designed for electronics that has worked amazingly well for me when working on stuff with small fasteners.

Disassembling the Launch 1

Safety brief: Just remember, you are working with a very sharp spring loaded knife blade. It wants to open. Handle it accordingly and play it safe.
All of these screws use a #6 Torx bit. I removed the clip first and then the three screws holding the handle halves together. Note how the axle bolt is held in place by a hex head on the left. You don’t need to do anything from the side with that bolt – I’m just pointing out it is nice and secure. If you look at the screws at the bottom – especially the one to the right, it looks like some medium strength thread locker was on them.
I missed it on first glance – this is the other half of the axle bolt – kind of like a Chicago-screw or post-screw. I saw the decorative half circles and wondered how they removed it and then I noticed the hole in the center and looked more closely with a flashlight – hidden down in there is a #8 Torx screw.
There must be some thread locker on this as it took some torque to break it free. I didn’t need to use a wrench or heat – I just had to turn more firmly and it came loose.
Looking at the white/grey stuff in the threads – there probably was just a bit of threadlocker to keep it from coming lose but I am not certain. I would tend to think there is because you can’t crank that screw down or the pressure will keep the blade from opening.
At this point, all fasteners have been removed. Notice how I have it turned over so the push button is up – you will want to do the same.
So the scale lifts straight up and off. It is a snug fit on the axle bolt so it may take some wiggling to get it off. Now I need to point something out – look how clean the machining is and the finish is consistent. So many tools and knives look like crap inside due to an “out of sight out of mind” mindset that it is refreshing to see how well this is done. Kudos to the folks in the Oregon Kershaw plant!
The top pin to the left of the push button is hand press fit in place. Pull it out first and the blade will want to rotate clockwise and then the big hole will present itself to the push button and the push button will lift out.
Yes, in the photo above I said remove the pin and then the push button. In my case I was taking pictures and wiggling the blade round – the push button came out on its own. At this point the spring tension is being taken up by the pin. It’s not a crazy amount of spring tension the blade open but it is trying to go a bit further so be careful. This photo also lets us see the removed push button assembly. Normally, the fat bottom portion is engaging one of the cut outs in the bade. Either the one at the top that is keep it closed or the one at the bottom that locks it open. When you push the button the fat piece slides out the way and the blade is released to either open or close. Note, the spring is not sitting properly in the base of the push button in this photo.
I would not have needed the little blue pry bar if I knew the stop pin simply pulls out. If I had slightly closed the blade to take the pressure off the pin, I could have easily lifted the pin out, then controlled the few more degrees of rotation the spring had left in it and the blade would have lifted right off.
The torsion spring is what provides the power to flip the blade into position. The act of the user closing the blade rotates the spring’s coils and store the energy waiting for the button to be pushed spring back into the relaxed position. One leg of the torsion spring sits in the channel of the handle and the other sits in the blade. In this photo I have laid the blade 180 degrees opposite of how it normally sits in the handle so you can see how the torsion spring sits in the two parts. It’s elegant. Notice the ample grease – I think it might be silicone grease. Anything that causes the blade to bind will slow or even stop deployment.
Here are the parts and you can see the nicely done flat torsion spring. Again, I should have removed the stop pin, then the push button and the blade would have lifted right off the axle bolt. This is it other than removing the stop pin which plays into re-assembly.

Re-Assembling the Launch 1

Putting it back together is pretty straight forward. In hindsight I would tell you if something seems complicated, you missed something. That was exactly my thoughts as I was trying to the the torsion spring oriented with one leg in the handle and the other in the blade.

I spent about 5-10 minutes trying to get spring in and had my “duh” moment. Given how the spring sits, no tool so going to fit in there. I thought to myself “I wonder if that that stop pin can pull out?” And it did.
Wow!! Removing that stop pin made it sooooo simple. Rotate the blade such that the torsion spring legs are seated and you will feel the spring working. Then put in the push button and its spring followed by the stop pin.
I wish they designed the spring to snap into the button but they didn’t. An old trick that I used here was to fill the cup of the push button with silicone grease. The grease in turn holds the spring while you install the assembly.
Rotate the blade just enough so you can install the push button in that first large semi-circular opening. You can then push the button down and rotate the blade into the next notch which is the normal lock open moment. In this photo the blade is at a funny angle because the stop pin has not been installed yet.
Notice the blade is pushed all the way down on the axle bolt. To install the stop pin, push the button, carefully close the bade and release the push button. It should engage and hold the blade in the closed position. This presents the hole for the stop pin wonderfully as you can see in the photo and you aren’t fighting the spring. Literally, the pin goes right in.
I put a light coat on silicone grease on this side of the blade as I had wiped most of it off fumbling around. I did clear the silicone out of the bolt if you are wondering. You can also see the stop pin is in its hole.
The handle half is reinstalled. I carefully held it in place and tested to make sure the blade still pivoted and the push button worked.
When you reinstall the end of the axle bolt, you will need to see how much to snug down the screw. I found that if I made it too tight that the blade would not fully deploy. After experimenting, you may want to put just a bit of medium thread locker on the screw to keep it from working loose.
Re-installed these too and with that am done.

Summary

Kershaw did an excellent job on this knife. I thought about doing the same with the Launch 13 and it looks to be the same mechanism so I didn’t bother.

If you are looking for an automatic knife, I am very impressed by the Launch 1 and 13. I suspect the whole line has similar workmanship. I’ll post links further below.

Reviewing the Kershaw Launch 1 and 13 Automatic Knives

Growing up as a kid in the 70s and 80s you’d see some guy in a move whipe out a switchblade and you’d know a world of hurt was coming. For years, I wanted one but couldn’t own one. Now that I own two, I’m trying to figure out how they factor into my collection to be quite honest.

I’m not handicapped so I can’t speak to how they would use one but other than the “coolness” factor, I don’t see the point compared to the tons of flippers / assisted opening knives that I already own. To be clear, I am not bashing them but I won’t be buying any more either – my curiosity is satisfied. Please note – I am impressed by the design and the manufacturing but have decided they just aren’t my cup of tea.

With that said you are going to get my honest opinion.

Some Background

I like Kershaw knives in general so an ad for their Launch series of automatic openers caught my eye. I’ve always wanted to try a “switchblade”, or more appropriately termed an “automatic”, so I shelled out $114 for a Kershaw Launch 1 and $125 for a Kershaw Launch 13. I figured that would let me try a couple of different designs and they have a number of Launch models for you to choose from.

One thing that appealed to me with both of them is that they are made in the USA. Kershaw has a production facility in Tualatin, Oregon, that makes these models as well as a number of their higher end Kershaw and Zero Tolerance blades. Part of the premium pricing reflects being built in Oregon vs. China.

Note: You need to know the laws and regulations governing automatic knives in your area before you buy one. The American Knife & Tool Institute (AKTI) maintains a page that can help at a state level but you still need to confirm about your county and city just to play it safe.

The Launch 1

This is a good size knife. The slightly “humped” design enables it to fill your hand and be held very nicely. Let’s talk specifications:

  • Blade length: 3.4″
  • Blade profile: Drop-point
  • Blade steel: CPM 154 – it is a tough stainless alloy that also holds an edge fairly well while being moderately easy to sharpen
  • Blade finish: Black Wash
  • Blade thickness 0.121″
  • Closed length: 4.6″
  • Handle material: 6061-T6 aluminum
  • Handle finish: Black anodized
  • Handle thickness: 0.47″
  • Overall length when open: 8″
  • Weight: 4oz

Pros: Weight and size are good, blade flips open with a snap when you push the button, very nicely made.

Cons: I honestly wish there was a safety. This thing opening in a pants pocket is going to really suck fast. Kershaw says it is “low-profile” to make it harder to trigger but even so – you push that button and it will open fast.

Launch 1 closed. Like the US flag. Lines are nice, clean and flowing. All of the screws on this side are T6 Torx. The handle is 4.6″ long, 0.47″ thick, 6061-T6 black anodized aluminum.
At the left are the two screws if you want to move the ciip to this side. The axle pin the blade rotates on is held in place by a T8 Torx. You can see the recessed push button that does dual duty both to allow the blade to flick open and also to unlock the blade once it is locked open.
Good view of 3.4″ CP154 blade with a blackwash finish. The blade is 0.121″ thick so just under and 1/8th inch that would be 0.125″.
Here’s a view of the other side. Note how the axle bolt uses the handle scale to elegantly hold the hex head in place so you can tighten the axle pin from the other side.
From top to bottom: 1. Kershaw Launch 1. 2. Kershaw Knockout with a Damascus steel blade.. 3. Kershaw Blur and 4. ZT 0357. These are all excellent blades. My favorite is the ZT0357 and the Knockout. All are made in Kershaw’s Oregon plant with excellent machining, fitment and finish.

The Launch 13

I like unique looking designs and the Launch 13 immediately caught my eye due to the futuristic look and wicked Wharncliffe style blade. It looks odd but it actually fits my hand very surprisingly – better than I thought it would actually. Let’s look at the specifications:

  • Blade length: 3.5″
  • Blade profile: Wharncliffe
  • Blade steel: CPM 154 – same as the Launch 1
  • Blade finish: Black Cerkote
  • Blade thickness 0.121″
  • Closed length: 4.5″
  • Handle material: 6061-T6 aluminum
  • Handle finish: Black anodized
  • Handle thickness: 0.471″
  • Overall length when open: 8″
  • Weight: 2.4oz

So, it is just a tad shorter but quite a bit lighter than the Launch 1. With all of the angles and skeletonized scales, I didn’t think it would be as comfortable as it is.

Pros: Light, A Wharncliffe style blade

Cons: Even though the push button is recessed, I am fearful of it opening in my pocket.

The scales are nicely done and are machined from 6061-T6 aluminum with a black anodized finish. The small screws are all T6 Torx and the nut on the axle bolt is a T8.
You can see the push button that both allows the blade to spring open and to unlock the blade once it is open. Interestingly, the axle bolt’s head is triangular instead of a hex head like the Launch 1 uses.
The Wharncliffe-profiled blade is very sharp. Yes the grind is simple but it’s a Wharncliffe 🙂
Here’s a view of the Launch 13 open from the other side.
The Launch 13 at the top and the larger Launch 1 at the bottom.
Notice the different handle angles when you get the blades in about the same plane.
From the top: Kershaw Launch 13, Launch 1, ZT 0357 and Kershaw Knockout with a Damascus blade (they also make one that is not Damascus wo that’s why I am pointing it out)
And the other side from the top: Launch 13, Launch 1, ZT 0357, Knockout with a Damascus blade.

Summary

The Launch blades are very well made. Of the two, I am partial to the Launch 13 because it is lighter and has a Wharncliffe profile blade – again, I like Wharncliffes. I can cross having an automatic knife off the bucket list but plan to stick with assisted opening flippers like the ZT 0357.

Would I recommend either Launch knife to someone wanting and automatic – yes, I would. The build quality is definitely there. How can I prove it? In the next post I will take the Launch 1 apart and let you see it.


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.

How loud is a GX CS4 Compressor? It’s not bad at all – what I also learned is that cheap sound level meters aren’t consistent

There’s an old saying that nobody is sure of where it came from that says if you have one clock you know the time. If you have more than one, you are never quite sure. The reason for this is that if the clocks have different times then which is wrong or right? Well, I guess now we have time servers, atomic clocks and what not to help answer “what time is it?”.

Now why did I open with that? Well, the only sound level meter I had to measure the decibels of anything was my phone and two different apps that kind of agreed. When reading reviews, folks would say that phone sound level apps were not accurate. Well, I decided to buy a sound level meter to be more accurate … that was in 2017 and I thought I knew how many decibels things were using my cool BAFX3608 meter.

Fast forward to February 2023

I decided to test my GX CS4 and I also wanted to test some airgun moderators so I thought I would order in a few more inexpensive sound level meters to get readings in different spots – a BAFX3370, a Tadeto SL720 and a XRCLIF-1359.

I was using my GX CS4 compressor to top off my 6.8 liter carbon fiber bottle and thought it would be a great time to get sound readings from relatively the same location. I lined them up and took a video to capture sound readings on each meter at a certain time by freezing the video.

Here’s the video so you can hear the compressor and see the meters:

How did they do?

Well, I recorded the readings at 4,11, 16, 21, 26 and 31 seconds. I then calculated the average of the four and compared the meters to the average. The BAFX 3608, BAFX 3370 and XRCLIF were closest. The Tadeo was introducing quite a bit of variation into the samples. With one exception at 26 seconds, it always registered the lowest decibels. Excluding the Tadeto, the average spread was 2.97db across the three meters. With the Tadeto, the average spread increased to 6.8db.

By the way, the manufactures claim +/-1.5db of accuracy for the two BAFX meters, +/-2.0db for the Tadeto and +/-1.5 for the XRCLIF. That means the ranges should have been at most 3.5db apart. The recorded data showed spreads far wider than that.

What this spread tells me is that the two BAFX units and the XRCLIF are in relative agreement given their stated accuracy. My tendency is to think they are closer to whatever the real measurement actually is and discard the Tadeto data. It also tells me that when you buy cheap uncalibrated sound meters you get cheap uncalibrated sound meters.

What about the apps?

I tried the both the “Sound Analyzer” and “Sound Meter” apps for my Samsung Galaxy S20FE. The Sound Analyzer reported an average of 79.3 and the Sound Meter app averaged 80. The sampling was done by holding my phone about the same distance from the CS4 and letting each app collect data for about 30 seconds. Given how fast the CS4 pumps, the apps had quite a few cycles to record.

This is a screen capture of the Excel file I created to look at the data.

Conclusion

I have a vague idea that the average sound level was somewhere between 81.5 to 86.1db as the machine operates if I exclude the Tadeto’s recordings. The samples were drawn at different times and the pump had a repetitive rhythm to it so I am sure the volume did differ but looking at the spread across the meters and the deviation from the average tells me that three meters are closer to one another (the two BAFX models and the XRCLIF) and the Tadeto is an outlier. The apps don’t really agree with anything either.

To wrap it up, thanks to my PC periodically synching its clock to a time server, I know it is about 9:20pm right now. What were the actual sound levels during each of those samples … now that I don’t really know with any precision – I have a ballpark range. I guess some day I will need to buy a quality calibrated sound level meter – what I probably should have done from the start. If you need to buy a meter and can’t afford a higher end unit – buy either the BAFX 3370 or the XRCLIF-1359. The BAFX 3608 is no longer made (as mentioned – I bought it back in 2017).

Here are the GX compressors from the CS4 down to the CS1
