DIY Sheetmetal Derringers 22lr Homemade Guns v3 Latch in Detail

[@KeithBair]

You could make the block out of steel now that you know what your break action lock will look like. Thus will make it last that much longer since it takes the brunt of the recoil. You could even go as far as buying some casenite or similar and case hardening the block/breach face, hammer, and trigger. That will make those parts last all the longer so when this derringer is handed down generation after generation, it will still be in proper working order. Good work!

[@jimafcarbon4433]

See, now that's a good idea ! The hammer and trigger on this one are 4130, so they can be heat treated. But making the block out of steel too would add a lot of strength where it matters. I like it!

I like that latch a lot. I might have to use that design on one of my next derringers

[@jimafcarbon4433]

I would like to see that. One of the great things with youtube is the evolution of these ideas. While there is still room for improvement, as of now, I don't have any changes planned. if somebody else tries it, they might have a better take on the process.

[@draufganger620]

I agree. I’ve learned a lot from others’ videos and I like seeing what others come up with. I’m glad there are people out there who enjoy this hobby and who share their builds and ideas on KZbin 👍

[@moderncavemanselfreliance8656]

I have made several terrible attempts, got a few to fire but didn't like it. I think I'm getting in too much of a hurry, and should use my drill press more. Thanks for sharing. About to try again and take my time. Trying to build guns like this with a toddler always around is much more difficult.

[@jimafcarbon4433]

Patience ! Video your build. We love seeing more Homemade guns!

[@Konik7000]

This is the best "DIY SHEET METAL DERRINGER" I have ever seen. It's just pretty. I have watched it many times. You've made significant changes to the design from the web. In your next clip, could you perhaps take a simple picture of the disassembled derringer (something like a scan)? Parallel to the table so that this design can be analyzed?

[@jimafcarbon4433]

Thank you! I tried to demonstrate a decent result can be obtained from the design with with mostly simple tools. I have a few other brief videos of this build. But yes. I plan to do more in-depth, detailed videos. KZbin doesn't allow real gun build tutorial videos, but I'll give as much detail as I can, for educational purposes.

Amazing to see the fi al result, very nice craftmanship and finish. Cheers

[@jimafcarbon4433]

Oh she's far from done. One day. For now, many other projects

[@rlbadger1698]

Maybe scallop in the brass around the latch, and grind down the tang on the latch to make it a button. Making the latch a button would smooth out the lines and make it a slicker pocket carry.

[@jimafcarbon4433]

Thanks, I like that idea. I had planned to make a 22lr/muzzleloader at some point. A short maybe inch of rifled barrel and another inch and a half of 30 cal. Could shoot 22lr like normal, or nail gun blanks to fire a muzzle loaded 30cal ball.

Hey Jim, loving your videos and work. Your plain honest comments are gold. Could you describe your workshop and what machines you use please? Also your knowledge on gunsmithing seems pretty solid and something I'd like to learn more about. What books, etc would you reccommend? Keep up the great work mate, cheers Rod

[@jimafcarbon4433]

wow, thank you for the kind words. im pleasantly suprised with the positive attitudes toward my content. Which I don't feel is great, at least my production value. I plan to do some videos on my shop, tools, techniques and a bit of history. Nothing I have is great, but I have a lot of money and time invested in my shop. My latest acquisition about 2 years ago is a Bridgeport as old as I am. It could use some TLC. I've had a chinese mini-mill for about 10 years and a grizzly lathe for about 7 or 8 years. I got my first TIG welder maybe 2 years ago. My dad was a part time gunsmith for 30 years.. For about 10 years now I've been a weekend warrior gunsmith. But I've always been a DIY type and love the problem solving type job shop projects. These little derringers are 95% hand tools. The designs are intended to be simple for the DIY tyoe to complete with basic tools. I'm obviously just starting with the video documentation of this kind of work. I'll take it as far as I can with youtubes limitations. Maybe people will be entertained, maybe we'll learn something. I can only hope to inspire others to take on a project of their own.

You've inspired me to have a crack at one, so there you go You ever thought about teaching it?

[@Bulgar1us]

Not bad bro. I would say I can try it. For barrel block I would use little metal stick under barrel..

I've thought of that too. Probably will do that if I ever get around to a black powder build.

[@xxersi12xxer81]

its very nice and litle i just start cuting sideplates but i chose a 2mm thick hard steel and its so strong to cut , i am intrested to know are these sideplates from brass and is it strong enough to prevent from explosion if you are using 22lr, i see all your videos youre making a very good job with these derringers

[@jimafcarbon4433]

The brass is certainly strong enough for 22lr. I wouldn't make one in 9mm without greatly increasing the size. Thank you for your kind words. Please post videos of your builds.

[@jimafcarbon4433]

Nice ! I love seeing others takes on similar builds. You might not want to hear this, it's not cnc or edm, it's all files man! I have a few sets of old Norton needle files I picked up in an estate sale. Sometimes I think I subconsciously make up reasons to use files. I'm working in a video now of some file work. Basically putting the serrations on the hammer and trigger. I've done some hammer spur checkering with files too. It's the closest I can get to being an artist.

[@armon8399]

Man that's so cool! Rifled barrel?

[@jimafcarbon4433]

Yes sir. Rifling buttons from the Ukraine are reasonable affordable. This barrel started out as a solid round bar. I milled to hex, drilled, reamed, chambered, rifled, then welded the lug. It's a process, but one step at a time is fairly simple.

[@JohnDoe-yg6ed]

No plate between the hammer and chamber?

[@jimafcarbon4433]

Just the lower 3/4 of the chamber. The top 1/4 is the hammer which contains the firing pin. The plans call for 2 pins, not a block. The block is the better way to do it. And the block is where my latch pivots. An even better way would be to have the block cover the whole chamber. A floating firing pin captured in the block.

As my calipers are inches, I'll let you convert. Outer diameter is .225 The wire itself is .038 Length of 10 coils is .930 or .135 for each coil. I like the overall length around 1.250. Which works out to 14-15 coils including the flattened ends

what is that barrel made of? how did u made that?

[@jimafcarbon4433]

The barrel started out as a 1 inch solid stainless round bar. I milled it to a hex, drilled, reamed, chambered then rifled. The bar was not quite big enough to make the barrel off center and leave enough to machine the lug out. So it was added later, stainless TIG welded.

that latch is neat but it wouldn't work in the pocket. would disengage to easily.

[@jimafcarbon4433]

True. I wouldn't carry one of these anyway, but you could find a balance on the spring tension where it wouldn't be too difficult to open yet would not likely open accidently. Could scallop the side plate and require the button to be recessed before opening. Many ways around it, but as a range toy, it's not a problem. I'd love to see other ideas though. Maybe something easier to make.
