Re: integral 10/22- what size outer tube and material?

I used a 1"x.060 316 tube, bought a KIDD pistol barrel and turned it down to a press fit, then pinned and welded the tube to the barrel. Bored out a shrewd muzzle brake and threaded it to be my endcap. I have a foam insert to act as a wiper. The first baffle is Ti the rest are 7075 AL. It turned ou...

Re: Completed form 1 5.56 NATO build

Bore the cones the other way around and use a boring bar for the inside and a standard cutting for the outside. I wouldn't leave all that material especially if you are just going to use a spacer anyway, that's a lot of wasted effort. This will ensure uniform baffle thickness, and greatly reduce the...

Re: High speed suppressor video

By virtue of my job I have access to some high speed cameras so I used on this weekend to film my From 1 45 ACP suppressor cycling on my 1911. The spring in the booster was just a wild ass guess for spring and mostly chosen cause it fit the dimensions I needed. It worked 100% from day 1 but I was n...

Re: FN "baby browning" diy projekt, make adapter and silencer.

That's exactly the problem I had. I made a threaded sleeve with a .265 bore, threaded .335x40 on the inside of the barrel and .500x28 on the outside. After only a few shots it broke just past the slide. It may be possible that I had bad stainless or I didn't do it well, but it never made it through...

Re: .065" wall safe for 316L 308 can?

Thanks guys, that's what I needed. Thought about plug welding all the baffles, but I'm only set up for MIG, no TIG, and figured all the MIG plug welds on the outer tube would weaken it too much. I'm planning to use thin (.049" wall) aluminum tube for baffle spacers with no skirts on the cones; that...

Re: .223 endcap thickness

What's the dimensions of your can and what material for the end cap? If its 1.5"x5" versus 1.5"x12" my answer will change. All in all, I personally think its a tad too thin. I'd want 0.050 or so.
