Video: Manufacturing an Eight Inch High Explosive Howitzer Shell Circa 1917 – Shows a Ton of Machining Operations

If you like to watch old school machining, this video from the Library and Archives Canada is pretty amazing. It’s a silent black and white video that is just shy of 54 minutes long. The title of the video is “Manufacturing an Eight Inch High Explosive Howitzer Shell At The Works Of The John Bertram & Sons Company, Ltd., Dundas, Ontario – Canada”.

The video steps you through the process as well as general view of the shop. This shows you manufacturing in an era where a lot of artisan skill was required to turn out products. It’s really fascinating to watch. The following are some screen shots from the video:

How To Find Barrels For Your Polymer80 Build on eBay

In my last few posts, I’ve covered OEM lower parts kits and customizing the parts in the lower. In this post, I’m going to switch to the slide area and cover barrels. Without a doubt, having the right barrel for what you want to do is a very important consideration. Now notice how I worded that – it depends on what you want to do. There are barrel built for reliability, with match tolerances, porting, threaded ends, extended barrels… it really depends on what you want.

When I built my first two Polymer80 pistols – a full size Glock 17 unit and a full size 34, I went with threaded match barrels from 80P Builder. They are both accurate with 115 and 124gr FMJ but I quickly realized the added length wasn’t really worth it for me at this point. The idea behind a threaded barrel is that it will allow you to thread on some type of suppressor or muzzle device. To do that, the barrel with the threading needs to stick out – in the case of the 17, it sticks out about 0.634″ inches.

The threaded barrel extends 0.634″ past the end of the slide in this Model 17 build.

You have to ask yourself – do you really need that sticking out if you want a pistol for concealed carry. With my 34, it is a combat pistol and length isn’t something I worry about. In fact, it is running a Tyrant Designs CNC T-Comp brake that does a remarkable job of keeping the pistol flat during rapid fire. The end of the day, the threading definitely gives you a ton of options with a little extra length and weight added.

The Tyrant CNC brake is both radical looking and effective. It’s found a permanent home on my first Polymer80 Model 34 build. You can see a hint of the front Tru Glo TFX Pro sight as well.

If you like the idea of reducing muzzle rise and some recoil reduction, another option for you is a ported barrel where the manufacturer of the barrel actually will either drill holes or machine slots into the end of the barrel to vent gasses. I’ve not used a ported barrel on my Polymer80 but I do have a cz.75 with a ported barrel and the porting definitely helps.

Another option is to go with a standard length barrel that is more or less flush with the end of the slide. My next 34 will have a Zaffiri match grade flush barrel that is fluted and has a deep crown to protect the end.

Bottom line, you have a ton of options in terms of functionality and looks that you can consider so spending some time thinking about.

Vendors I’ve Heard Good Things About

So, you can do plenty of reading on offerings from vendors. The options are amazing – length, twist rate, thickness, threaded, fluted, ported, color and so forth. Just make sure you get a generation 3 compatible barrel and it matches the model of pistol you are building. In researching barrels, the following have good reputations: Agency Arms, Faxon, Glock OEM, Killer Innovations, Lone Wolf, Silencerco, Storm Lake, Wilson Combat, Zaffiri and Zev. If you click on the vendor names previously listed, a dedicated tab will open showing current offerings on eBay, if there are any.

Customizing The Lower Parts In A Polymer80 Frame Via eBay

In the last post, I recommended that builders new to Polymer80s either start with an OEM Lower Parts Kit (LPK) or at least have one just in case their aftermarket parts are out of spec or something fails. In this post we are going to talk about customizing these same parts.

When you look at a Glock Gen 3 LPK for the model of pistol you plan (17, 19, 34, etc.) the following tend to be the parts you need:

  • Slide stop lever with spring
  • Slide lock & spring
  • Magazine release & spring
  • Trigger with trigger bar
  • Trigger housing with ejector
  • Trigger spring
  • Trigger pin
  • Trigger housing pin
  • Connector (5 pound)

I have seen aftermarket parts on just about all of the above and it depends on what you are buying. For example, you may just decide to replace the trigger shoe and need everything else or you may buy an entire trigger group with everything except the pins. The point is that if you decide to customize some or all of the parts, make sure that you have eveything required – springs, pins, etc.

For example, on my PF940V2 full size frame configured like a Glock 34, I am using an Apex aftermarket trigger shoe and bar but everything else trigger related is OEM glock. On my PF940V2 configured like a Glock 17, I am running a Zev Fulcrum Adjustable Trigger Upgrade Kit that includes the whole trigger assembly, firing pin, springs and plunger. Which of the two is smoother? I manually polished the Apex very carefully and it is very smooth. The Fulcrum is dragging some and I need to polish it one of these days. For as much as I paid, I’m surprised that any polishing is needed but it is a light short pull though.

So, when you do your lower, think things through. I automatically go with an extended Glock slide stop found on a model 34, an extended slide lock, a Vickers extended magazine release, all stainless pins and the trigger is an “it depends”. On my next planned 34 build, I am going to mirror polish all of the OEM Glock parts and then decide where to go from there.

My Glock 34 build – Apex trigger shoe & bar, Glock 34 slide release, extended slide lock and Vikers extended magazine release. This combination works great for me.

A few eBay buyer tips for you:

  • Look at the number of transactions and rating of the seller. If they have less than 10 sales, your potential risk increases.
  • Stick to Gen 3 parts. Glock has been evolving their pistols for a while now and the Polymer80 frames are designed with Gen 3 models in mind.
  • Make sure the parts you are looking for match the model you are building. Not all parts are interchangeable across models.
  • If the deal is almost too good to be true, it probably is. For example, you’re not going to find a high-end assembled slide with barrel for $50. Sure there are used parts and good deals but there are also scams. This is another reason to look at the seller’s ratings.

Gen 3 Triggers

There are a ton of groups making replacement Glock triggers. I’ve used Apex and Zev personally but have also heard good reports about Agency Arms, Overwatch Precision and Velocity Arms. Please note if you click on one of the previous names, a new tab will open with a dedicated search for that brand of trigger will open. With the triggers, you definitely need to pay attention to what comes with your purchase and what else you will still need to source. The following is a generic search on Glock Gen 3 Triggers:

Gen 3 Pins

You have the option of using Glock OEM pins or aftermarket. Now many will tell you that the polymer trigger housing pin is just fine and is proven. I had the polymer pin snap during a range session with my Polymer80 Glock 17 that has a Zev Fulcrum trigger. Why, I don’t know but I only use stainless pins now. I’m running pins from GunTools.

Gen 3 Extended Slide Lock

The OEM slide lock is too small for me. I have big hands and not a lot of feeling at my fingertips so I find myself fumbling around for the slide lock. An extended slide lock extends the unit just a bit further and enables be to more easily actuate the unit. I am runnng Deltac units but have also seen good reviews of units from Bastion, and NDZ. Note, you will need to supply the spring in every case I have seen.

Vickers Tactical Tactical Extended Magazine Release

One last part to cover – the magazine release. I can’t readily actuate the shorter OEM unit. I find I need just a bit longer release and really like the Vickers model that is made for them by Tango Down. Now, if you are wondering why, some units are so long that it is very easy for them to get bumped and release the mag. For some units, even laying the pistol down on it’s side might actuate the release. That may not matter for a competition pistol but I’d rather find a balance between ergonomics and reliability, hence my exclusive use of the Vickers model. Note, in most cases including the Vickers, you will need the spring. Here is a general listing of extended magazine releases:

Glock Gen 3 Lower Parts Kits (LPKs) on eBay For Polymer80 Builds

In the last post, I gave you a general link to Glock parts and now we’ll start diving a bit deeper. When you are assembling a Polymer80 pistol, you will need a lower parts kit (LPK) that either you need to buy or will be part of a larger kit depending on what you are doing. If you are new to building, it is hard to go wrong with with an original equipment manufacture (OEM) Glock LPK vs. aftermarket that might have some challenges and others are best avoided. To avoid headaches while you learn, you want a Glock Gen 3 LPK. In the next post, I’ll go over the parts if you want to customize everything and you can do that but to start, go Glock.

What is in a LPK?

You will want to confirm the parts list with your seller, but here’s what would be in a full size Glock brand Gen 3 LPK:

  • Slide stop lever with spring
  • Slide lock & spring
  • Magazine release & spring
  • Trigger with trigger bar
  • Trigger housing with ejector
  • Trigger spring
  • Trigger pin
  • Trigger housing pin
  • Connector (5 pound)

LPKs are on eBay from Glock, Polymer80, marvel mystery parts (in other words, some have no maker identified and are to be avoided) and others. Again, for a newbie, I’d recommend starting with a Glock brand LPK to avoid potential stacked tolerance issues that you would need to address – if you are ready to drive in with all custom parts, you definitely can but it is still handy to have Glock OEM parts around for troubleshooting or spares just in case.

A few eBay buyer tips for you:

  • Look at the number of transactions and rating of the seller. If they have less than 10 sales, your potential risk increases.
  • Stick to Gen 3 parts. Glock has been evolving their pistols for a while now and the Polymer80 frames are designed with Gen 3 models in mind.
  • Make sure the parts you are looking for match the model you are building. Not all parts are interchangeable across models.
  • If the deal is almost too good to be true, it probably is. You’re not going to find a high-end assembled slide with barrel for $50. Sure there are used parts and good deals but there are also scams. This is another reason to look at the seller’s ratings.

Finding Parts For Your Polymer 80 Pistol Build on eBay

I really like building the Polymer80 pistols (Why Polymer80s Excite Me, Tips for Smooth Polymer80 Pistols, and Troubleshooting Your Build). What attracts me is the 1911-like grip angle, Picatinny Rail and the ability to customize the pistol however I want it. You will not save money doing these builds but the results are really cool. When you are planning a build, there are the expected sources of parts like 80P Builder and Glock Store but also a big one that might surprise you – eBay. I’m going to do a series of posts over the next few days with links to a variety of parts listed there.

A few tips for you:

  • Look at the number of transactions and rating of the seller. If they have less than 10 sales, your potential risk increases.
  • Stick to Gen 3 parts. Glock has been evolving their pistols for a while now and the Polymer80 frames are designed with Gen 3 models in mind.
  • Make sure the parts you are looking for match the model you are building. Not all parts are interchangeable across models.
  • If the deal is almost too good to be true, it probably is. You’re not going to find a high-end assembled slide with barrel for $50. Sure there are used parts and good deals but there are also scams. This is another reason to look at the seller’s ratings.

Polymer80 parts in general:

Video: How to Make a Japanese Katana Sword: Exquisite Detail Of the Hamon and Engraving

I thoroughly enjoyed this Japanese video that covers the forging, engraving and heat treat of a Japanese Katana by a Master – Sadatosh Gassan. The video provides a great overview and while it is in Japanese, there are subtitles in English.

What I found most fascinating was the detail of the creation and application of the clay to create the hamon. Sadatoshi-san also is shown carefully engraving a dragon around a plum tree.

He evenly applied the clay and is now drawing the hamon pattern into it prior to the heat reat.
Here it iss just prior to the firing.
Carving the dragon into the blade.
The end result is beautiful.

The Video


I hope you found this video as interesting as I did!

Video: Forgotten Weapons Reviews Soviet AK Magazines

In this short video, Ian gives a brief overview of Soviet magazines – notably the slab side, ribbed, waffle and bakelite. As always, Ian does a great job and this is worth a watch!

The first generation was a heavily built (over-built) magazine known as the “slab side”.
After the slab side, they developed the ribbed magazine that was copied by many countries.

To reduce weight they developed the aluminum waffle magazines- so named due to all the reinforcement ribs. It was relatively short-lived because it was not durable enough.
After the waffle mag, they moved to the Bakelite magazine that actually was a glass reinforced polymer. This gave them what they wanted – light weight and durability.
When the AK-74 was developed, they went straight to polymer and never developed steel mags. Note, other countries did build steel AK-74 magazines but the Soviets did not.

The Video


I hope you found that video useful. Ian is a wealth of information and you can learn more about his work at Forgotten Weapons.

Video: Apex Gun Parts’ Croatian AK-47 Magazines Being Manufactured

While digging for videos on AK magazines, I found this one posted by Apex Gun Parts in 2016. It shows their Croatian AK-47 magazines being manufactured. While they don’t come right out and say they are being made by Zastava, I have a hunch that they are.

I would like you to compare this video to the one I previously posted showing Matra Group’s process. Matra is using older general purpose machines and there isn’t much attention paid to worker ergonomics and lighting.

Now, watch this video and not the differences. This video is showing a much more modern plant where there is also detail provided on their quality control processes and they show the jigs that they use.

The Video


I hope you find the video interesting. Apex Gun Parts is definitely a group that I buy stuff from and have no problems recommending them. I don’t have any experience with these mags so this video is really to let you see the differences in manufacturing.

Video: Matra Group Manufacturing AK-47 and AK-74 Steel Magazines: From Sheet Metal To The Finished Products

The AK-47 rifle and it’s “banana” 30 round magazine are classics of rugged functional design. While I’ve posted many videos and how-to articles relating to various rifle and pistol variants, I’ve not really covered the steel magazines at all.

I was surfing around and found Matra Group located in Bosnia-Herzegovina. In 2015 this small manufacturer produced a video showcasing their small facility that makes a variety of steel magazines for AK-47, AK-74 and even Lee-Enfield rifles. The Lee-Enfield may be due to those rifles being supplied to the Yugoslav Partisans in WWII to fight th axis armies.

In the video, they show employees starting with sheet metal and stepping through various steps including stamping, machining and spot welding. For the most part, you will see a very labor intensie process using older general purpose machines. If you like videos that showcase how something is made in and old-school fashion, you will find this very interesting.

Here they are cutting the initial sheet down into usable blanks.
Making the front piecee that will lock onto the front trunnion.
Spot welding the two body halves together.
Gettingg ready for final assembly.

Here’s The Video


I hope you enjoyed the video! I definitely found it interesting and informative. Just to be clear, I am not endorsing the magazines – I’m just showing their manufacturing process so I can then compare it to the manufacturing used to produce the Croatian AK-47 magazines that Apex Gun Parts sells.

Motivational Video: US Navy Seals and SWCC – “Never Quit”

Many folks have heard of the US Navy’s Sea Air and Land (SEAL) teams. The SEALs have been in a ton of movies and books but they are supported by another critical special warfare group – the Special Warfare Combatant-craft Crewman (SWCC). These are the teams that man the small boats that deliver and pick up the SEALs.

I have a lot of respect for the SWCC crews and get a real kick out of their boats – wow. These things are packing some serious firepower.

So, I ran across this cool motivational video this morning and thought I would share it:
