Is this design actually safe to shoot? Is an end cap screwed onto a seamless black pipe really enough to handle the pressure of a 12 gauge shell?

Perfectly legal to manufacture firearms for personal use.

It doesn't work, it just makes some shitty crystals.
>>
Probably. Just make sure it is decent thickness at the breach end. 1/2 inch width steel sounds safe if you want to be triple sure

you must have forgotten to put them in the microwave together with the shot shell used.

Would applying red loctite be a good idea if I want to be qauadruple sure?

Also wouldn't mind if people shared other, more sturdy designs.
>>
>>35137774
Short answer: yes, it won't explode.

I made one in high school and tied it to a 2x4 for a stock and it worked good enough for an afternoon of fun.
There are pretty easy ways to make a slam-shotgun that work much better. Notably in the firing pin area.

Care to elaborate?
>>
>>35137774
Yeah. Royal Nonesuch did a torture test with one. They are retardedly strong. I'm talking "can take multiple rounds of 3" high brass being fired into a barrel rammed full of dirt and gravel" strong.

Yes, just replace the wooden dowel with something metal and harden the nail.

Works in the Philippines.

>>35137774
Yup

Remember though, to be legal the barrel has to be >18" and the gun >26" overall. At least as far as I know.

Well, kind of. I was planning on building it anyway. Total build time was 4hrs, would have been much shorter but I was winging it.

I am under no illusions about it's quality.

>>35143945
Game load, fired it once. You can see it really fucked up the shell.

Are you a fucking beaver? Seriously wtf is that? Why didn't you carve a half decent grip out of a 2x4?

This kind of intolerance is not welcome on /k/, if anons want to live their life as a beaver, that's entirely up to them.

There you go. It's not quite finished but it's a muzzle loader I made out of a chunk of 12 gauge barrel I cut off of an old break action. Kinda lost interest and haven't touched it in a while but It shot well when I tested it with some fuse and I think 75gr of black powder.

did you not put a spacer for the nail?
its only supposed to stick out like a millimeter
>>
>>35144453
Because there was a perfectly fine treebranch nearby and I didn't want to waste a 2x4.

>>35144504
40

>>35145145
My pipe is a little large so there is a little much room for expansion. The spacer is there, but it may also be a bit short.

Wrong size pipe would explain it. Mine never fucked spent shells like that.
>>
>>35146611
How many shots did you take with it?
>>
>>35146666
25 round box of birdshot and a 5 rounds of 00. Stocks ok for hip shooting but shit shouldered. Decided to make a new stock before trying to use it more. Its a incredibly low priority. Good chance ill never shoot it again.

Any luck? Did you try it? Where do you live and would you mail me one?

What size of pipe is the correct size?
I thought the standard was shitty 3/4 inch black / galvanized pipe. I hope I didn't get the wrong stuff..
>>
>>35146611
I was wrong, the pipe fits pretty good. The firing pin is way too big I think. It looks like when it goes off there is still a pretty good gap that allows the shell to drop into the larger pipe and expand.

>>35145145
This anon is right. Lesson learned, I will remake it with a bail for the firing pin, the threads on the bolt snag the shell resulting in fishing it out as well.
>>
>>35146851
you need the breach to be flat.
if you glued a thick washer over that nut it would probably be ok. the way it is now is really bad.

3/4" black pipe, mine came with what I am assuming was anti corrosion coating that I cleaned off. Pic related is the fit with 3/4"

>>35146611
Forgot to mention yours looks pretty nice.
>>
>>35146871
Yeah, swapping it out for a nail.
>>
>>35144677
You may want to join the two pieces or put more clamps on the back section. I am worried with enough recoil the leverage allowed by the rear piece will break your clamp.
>>
>>35137869
>Would applying red loctite be a good idea if I want to be qauadruple sure?
No, if it fails it will splode, not come unthreaded.

I have a few saved photos of slam-fire shotguns. I'll post, to give you ideas.

It's black powder so there isn't much recoil. I lost interest in this project a while ago though and I don't currently intend to go back to it.

Ah, alrighty. You should pipebomb it for shits and giggles.

awesome, thanks anon. That's the same exact picture I get when I put a shell in.
Also I have a picture or two in the /gg/ gunsmith general, can't post them now.
