Re: Griffin Taper Mount Comp Specs Inside

When I bored the ID of the end-cap where it was to be threaded for the Griffin I used a cheap brazed import boring bar it flexed terribly and I ended up with a severely tapered hole. I spent a bit of money on propper boring and inside thread tooling and turned an end-cap this time I'm very pleased ...

Re: "Baffle" material?

Yeah, that makes sense. Ultrasonic jewelry cleaners are $25 on amazon, so that's not a big deal. I might see if I can find a silicone "release" spray, like basically mold release. From working with silicone before, the short version is "silicone sticks to anything, but nothing (except silicone) sti...

Re: "Baffle" material?

Except the ATF prohibits replacing baffles unless done by 07/02 SOT. Then the cost goes way up. That's the reason to build the most durable efficient suppressor the first time. I prefer to build multical cans that preform and last. "Except" what? Have you actually worn out a .22 rimfire suppressor,...

Re: "Baffle" material?

I disagree, I think it's actually a pretty reasonable idea. A356 can be plenty strong enough for a 22 LR suppressor, especially in a material like that where it's mostly surface skin; it depends on the structure and baffle shape though. I think that stuff is worth a shot; personally I'd choose the l...

Re: Commercial vs "kit" vs "dyi"

Re: $350 form1 .22 build

I'm all for building your own stuff, but I don't really get the appeal of some of these solvent trap kits, given the cost and other factors. For that same $350, you could have had a good commercial .22 can that is smaller, much lighter, and quieter. I mean, it would be different if it was something ...

Re: Where did i go wrong with this 9mm can

JMO but I think you cut the ports way too large and deep. The back side port looks like you put the center of the end mill out past the edge of the hole. Also, if you cut one of the K skirts down to a smaller diameter, it could fit inside the rear end cap. Do the same with the face of another to fit...

No spanking, but if you know both numbers are wrong, why do you think they are valid for comparison? You're assuming both are equally wrong so that the difference between them is valid, but that is most likely not correct either. Guys, do some research on these sound meter apps.

Re: How much more can I expect from this? (300 BO)

The sound level is being measured with a dB meter on the fast setting. Being careful to use consistent test conditions, I went from 117dB (bare barrel) to 103dB (with suppressor). As a relevance check, I did the last measured test with bare ears. My ears say 103dB is too loud. You're probably using...

0000 steel wool is referred to as "four aught" wool (like how 00 Buck is called double-aught buck). It does work very well for burnishing aluminum and titanium on the lathe.

Re: .308 Brake Mounted Suppressor (Picture heavy)

I appreciate the advice. The trouble I was having turning it is that my table is too small and not enough travel to get to the brake without more than half of the spindex base hanging off. I think I will have to drill into the base to get a better foundation. Trying to clamp it down in the front di...

Re: plastic coated bullets and silencers?

hardcase, just a suggestion - you can run powder coated cast bullets as fast as jacketed, at least up to 3,000 fps or so, but harder alloys are necessary for high pressure, and gas checks are still required in a gas operated system like an AR. Using a softer alloy like air cooled wheel weights will ...

Re: plastic coated bullets and silencers?

Strobro, you either need better coatings, or you aren't baking them long/hot enough. Are those Harbor Freight powders? Are you baking with an oven thermometer so you know the actual temp? The recovered bullets should not look like that; something is wrong with either your coating process or your bul...

Nice, thanks for the pic.

Now that you've used it, do you feel like the 50* exit cone was a good idea? I'm planning to make a similar end cap for mine (also a 30 cal), and have been pondering different ways to incorporate a cone in it without making a long bore section.

Re: Lathe purchase

think that would be a mistake, based on my own experience. You give up a lot of capability with smaller lighter machines, and you should be able to find something lightly used for half the cost or less, on a bigger machine. G4003G isn't a small machine. Small enough you can fit it into your home sh...

Similar, except the blast chamber will be same OD as the baffles, and the outer chamber will only be connected by a few small holes. I have not settled on how small or how many.
