Just a little weekend project. https://youtu.be/qPV2d7B2BjI?si=Os7-1\_AUA9XhsHzV

I just finished my single shot target pistol about a month ago. Yeah, it’s ugly, but I built it from the ground up and I’m proud of it. I manufactured everything from raw stock with the exception of the springs. Barrel machined from 4140 steel. It was drilled, reamed, rifles and chambered on my lathe. Frame is 3D printed from PETG. Bolt body, firing pin, sear and locking pins are all machined from 4140 steel. The rest was made from 1018 mild steel.

Considering this was my first homemade barrel (and first homemade gun, in general), it came out exceptionally well and is very accurate. The picture doesn’t show it, but I’ve attached a picatinny rail to the top of the receiver and put a red dot on it. It’s currently one of my favorite guns to shoot. I’ve put approximately 1500 rounds through it so far. I have a list of improvements I want to eventually make to it, but for now it works.

UPDATE:

Since some of you have asked for pictures of the internal components: https://imgur.com/a/jTyaGkb

I’ve numbers the components. Feel free to ask questions.

long story short I found this broken stock at a pawnshop for 15 bucks. found out it was from a Brazilian 1908 Mauser so I bought a vz24 barrel for super cheap and then the action for relatively cheap hoping i could put it together. threads for the barrel and receiver matched but seized up about half way on. turns out the receiver was warped so it would never accept the barrel.

i ended up just grinding the threads off the barrel until it would screw on. I don’t have any pics of the threads (it was a pain to get on so I’m not taking it off anytime soon) but lets just say it was pretty bad.

at the present I’m probably just gonna hang it up on my wall as a little display but theres a little voice in my head that’s telling me to shoot it. 8mm Mauser is no joke and im afraid the chamber pressure will just shear the pitiful threads that are left. obviously would rig it up and shoot it from a distance but ultimately I’m a little conflicted. If any of you have been in this situation let me know.

im sorry i dont have any pictures of the threads but it kinda looks like the last picture

Here’s a it broken down so you can get an idea of how it works.

Some of you have probably seen the development of 43R, a caliber that's intended to 3d printed and shot out of an off the shelf pipe. I have found an adequate parent case for this pipe as well, and it's been going great so far. Just a little plinking load for now, a single piece of 00 buck with a printed sabot. Sabot is heeled, as the pipe has no rifling or chamber. They go through a 4x4, haven't gotten to chrono them yet, but my guess is going to be somewhere around 1400-1500 fps.

I'll be testing them pretty thoroughly moving forward, and releasing process/loads if all goes well. I figured that you people would probably be more interested than the 3D2A crowd.

at the moment I'm using some coins as spacers, which fixes the issue you can see with the trigger not catching. don't worry, the hair tie trigger is temporary. if I can, I'll test fire this and the 7.62x25 pistol in the next few hours, and I'll post the footage if they fire. the bolt weight for both is a tad bit low, so I'll not be firing them from my hand for a while.

Update with testing footage of the Fulcrum PDW Chassis.

This is meant to be a sleek, simple design to turn your Glock (and gen 3 derivatives) into a PDW, while preserving Pistol functionality.

In the same vein as Recover Tactical, Strike SMC for a fraction of the cost.

When I get to round 15 the magazine keeps cracking along the magazine release noth,what should I do

Did some work on the De Lisle bolt. The original bolt head threads are 72 degree that were only used on the Enfield so, instead of trying to match those threads, I sleeved the bolt head and cut 7/16” 20tpi 60 degree threads. This operation also required timing the threads to ensure that the bolt head would be seated fully when the bolt is closed. The bolt and barrel face both had to be recessed and the firing pin channel drilled deeper to make room for the firing pin spring in the shortened bolt. The bolt handle has been dovetailed for the rubber insert to silence the bolt closing. I had to cut the bolt knob off to fit it in my lathe spider so that had to be welded back on as well. There’s still more work to do shortening the firing pin/spring and cutting the ejector groove in the bolt head. I’ll also have to make a new extractor since the old one won’t work with a recessed bolt face. And the barrel still needs to be chambered.

I’ve read that the 3 hardest parts of a De Lisle build are the magwell, cutting the barrel clearance in the action, and shortening the bolt. I fully agree with that.

Been using different brands of .22 nail gun blanks and some steel/copper ball bearings as ammo and found it has worked fine but was wondering if you guys have any alternatives, something that’s easy to get ahold of and maybe something more reliable like a center fire cartridge.

Since most Glock 44 owners have probably already heard that Glock finally managed to release a 15-round magazine after "only" 7 years, many may be wondering what to do with their "old" 10-round magazines.

Here’s the deal: you need your original 10-round spring, the base plate, the lock plate, and then print a new body and follower...

Surprise – you’ve just upgraded it to a 17-round Glock 44 magazine! 😉

Any Glock 44 owners out there willing to give it a try?

My saga of continuing to try and encourage you guys to try new 80% platforms continues. Episode 3 in the 80% DS1911 kit build tutorial series covers the slide to frame fit. TL;dr it’s not hard even with just hand tools. The only intimidating aspect is the time and effort it takes. This was somewhere around 3.5 hours total. But the result is a zero wiggle, perfectly smooth fit.
