Re: Build Pictures: 300 Blackout, Ti and 17-4PH

This has always been one of my favorite builds on here. The “tube” design is something I’ve been wanting to do, Since it’s bigger that I normally work with, I’ve been waiting on a paying job to come in so I can justify purchasing the drill and boring bar.

Re: Barrel threading

For muzzle threads where the customer needs to be able to attach anything, I am threading to a spec, which with my machinery, I am able to hold the PD in a tight spec where 3A and 3B overlap I am not sure why suppressor manufacturers in NZ don't thread to a spec.

Re: Cone baffle drilling

Drilling a hole is 100% the wrong way of making a bullet passage in a baffle. Bore the hole so its round and concentric to the centerline.If you must use a drill bit spin the work-piece in a four jaw for precision followed by a reamer. I only mention this so more people will have success in buildin...

Re: Thinking of a form 1 ar15 9mm build questions

I'm working on a permanently attached 1.625" diameter, 10.625" suppressor for a 5.5" barreled 9mm AR. I started with 316 stainless because that's what I had laying around. I am planning on 7075T6 internals. After machining the end caps and tube, I decided it is way too heavy. I am going to start ove...

Re: Form 1 recore questions

If a licenced manufacturer does the work and the serialized outer tube remains the same, then no additional tax must be paid. If you do the work yourself, each part you make will require a Form 1 and $200 tax. I suppose a guy could get away with legally re-coring a can with only one tax stamp if he...

I'm a firm believer that if the ATF kicks in your door to check if you re-welded the endcap on your F1 suppressor, you were already in some serious s--t.

If you're going to sleeve over, I'm not sure I'd use a filler. Just because you'd have to turn it down again. The outer sleeve, w/ filler, would make it a superior joint.

What type of SS is this?
Sleeving over, I'd agree.

I wouldn't think twice about parting it off, beveling each side being sure to remove every bit of carbon and TIGing it back together. I'm not familiar w/ the details, but I wouldn't bevel the parts. I always fit thin-wall tubing to a tight, square, buttweld. Back purge and TIG away. Should be a com...

Pretty work. :) Have you thought of making inert rds in other sizes? I have quite a collection. My dad brought home 20mm and 30mm GAU rds from work in the '80s. But we haven't had them since the '90s. :( 24.58mm is an odd size. Maybe you could make some inert .995 JDJ or other cartridge just for di...

Re: Shrink fitting end caps

I'm thinking if you had to do this, it would be best to make the end caps fit over the tube instead of inside. At least this way the expansion from pressure and heat would be working in your favor. I'm not looking any of this up now so it's pretty much coming out my ass, but say your end cap is .003...
