Win Mod12 Trench Gun Conversion

Yes sir, and thanks to folks that help out along the way really means the most...

Next attempt hopefully will be more sophisticated. I'd like to have the pipe cut in half and use it to make a die of sorts. I'm not sure how soon that will be - I need to locate a shop and band saw that will undertake a small project.

Meantime I'll check in time to to time...

well done. I knew you would do it fine...now if I could get a bayonet adapter(s), I'd ask Ryan make me some too.

Does anyone know what type rivets are used to attach the shield.... brass or steel...?

what type rivets are used to attach the shield

For all the world, I thought they were electro spot welded? Permanent fixture...

[Madcap]

You may be correct. I thought I'd seen some that were riveted but they may have been repros...

I realized how easy it could be to roll the rear edge and add the two dimples so I couldn't resist giving it a shot. A ball peen hammer and the steel pipe easily rolled the rear edge. I learned something else in the process and I'm really pleased with how finished it looks.

A 5/16" hole was drilled into a piece of PVC pipe to capture the dimple as it was pounded in with a drift punch that was ground flat and filed round.

Some Perma Blue was applied and I was surprised how quickly and extremely well the metal accepted it and reacted.

The bow in the shield bothers me but there must be way to deal with it somehow. This is just trial piece anyway so hopefully the next one will be a more improved model.

The drawing’s done and filed. I’d be happy to send it to anyone that wants it.

The laser cutter, SendCutSend, is super easy to order from.

You should be! A couple more tweaks and you’re there.
I’m impressed!

Really only thanks to your interest and generosity has this been anything at all. It's been interesting and a good learning experience for me and I'm looking forward to doing some refining when I can get to it.

Only thanks to your interest and generosity could it have gotten anywhere at this point. It was a bit intimidating for me to start on it without more tools but as it turns out I had all that was needed and has been a satisfying learning experience. It reminded of my dad working in his basement shop most nights after work years ago. I think I must have inherited that part of his DNA.

I'm treating this first piece as a trial and look forward to some refining on the next one. As a note I think the one longer flat may be a more correct length but I want to see how the next short piece turns out first.

Finally got together with a friend early this afternoon to rout a groove in a 2x6. The idea is to press a 1" pipe down onto the flat that will be held centered with some nails both sides or whatever. Next step is to visit another friend with an hydraulic press and force the pipe down over the flat into the basic shape needed for the heat shield.

Additional final fitting probably will be required plus the rear of the shield end will need the rounded edge.


Not sure when I'll get to the next step of using the press but will get back with results sometime soon. If the second one turns out as good as expected the third, and slightly longer flat will be shaped at the same time.
