Difference in sound for different material?

A buddy just Efiled for a .22 suppressor. He wants me to help him make an exact copy of my all Ti can, but he doesn't want to spend that much on raw material so he asked me what would be the drawbacks from making it out of 100% AL. I told him the same durability wouldn't be there - he'd need to be a...

Re: possible alternative end cap mounting

My tube and caps will be 316 stainless. Do you already have the material? If not, you might want to consider something easier to work with. Definitely get some AL or CRS to practice with instead of fighting 316. Also, are you starting with a chamfer on the part before starting to cut the threads? T...

Re: possible alternative end cap mounting

Next do your female threads. Get those exactly how you want them. Then do the male piece and keep adjusting until it fits the way you want it. Care to explain you reasoning? I always do the male first, they are much easier to measure (and thusly easier to get them perfect). For a silencer as exampl...

Re: Would you guys please critique my design ???

If I wanted to use washers & still keep it simple I'd do something like this. Washers a little oversize & sides ground to fit well.

Re: Light 223/heavy 22lr hybrid?

Is the .223 for a bolt gun that will see occasional use or an AR that will see hundreds of rounds per session? The good news is a decent .223 suppressor will get your 22LR Hollywood. The bad news is the decent .223 comes with some heft to it. Depending on your 22LR host, you're going to run into iss...

Re: New lathe purchase, is this enough?

If a 30" bed isn't too big, but a 40" is, you don't have enough room for the 30" either :) You will want/need free space left of the chuck end. It's a lot easier working on a barrel (for me anyway) going thru the spindle. An outboard cathead plus the chuck are much faster to setup tha...

Re: New lathe purchase, is this enough?

PM has a lot of 'LB' variants for their lathes. Meaning large bore. Haven't been on their site for a long time, but maybe the one you want has that for just a small upgrade cost? Call Matt there & ask him. He's a real nice guy & extremely helpful. Mine is real similar to the G4003G. It has a...

Re: Extended Nose K-Baffle

I've made them similar but not nearly as long as what you have pictured. Maybe .075" longer than the edge of the face. I'd worry about accuracy/stabilization issues running through that many long 'tunnels'. Depends on bore diameter I guess.

Re: 10/22 integrally suppressed barrel suitable for 60gr SSS?

I only shoot them out of a 1:9 AR w/ 22 conversion kit. My 10/22 sends them everywhere. They don't cycle either rifle for me, but I'm sure either rifle could be purpose-built around that round to cycle reliably.

VC19NC is Volquartsen part number. Around $300.

Re: 308 design critique

What part of NC?

Is your tube already threaded? Might not be able to do that on a 7x12 - they run out of real estate pretty quick :)

Keep in mind 303 isn't as 'stainless' as one would expect - it will require regular maintenance. Machines nice though.
