Re: "All caliber" cone design questions

Why not just make the cones the way you want from the beginning? I'm also curious as to the insanity of battery spacers being made from inconel?! Is that a real thing?

Re: blast chamber length

For a closed action, super sonic, there are no worries about blast chamber volume. If you're shooting subs, chamber volume, and design have a direct effect on frp. For gas operated firearms, blast chamber volume determines the amount of back gassing. That's it in a nutshell.

Re: Want to build a 2" OD 5" length form 1 for an AK

I managed to machine the little beast fine, but I wrecked two parting tools, and two saw blades parting that little demon steel! Managed cutting it with my plasma cutter finally! Told myself it'd be worth paying the tax for a new set of internals, vs. the carnage that 718 inconel brought to my world

I'd rather pull my own nose hair out one at a time than machine 3" inconel baffles. I made one out of 718 alloy.....once!

Re: Question about time between completion and engraving

Being the "maker" it seems to me that title entitles you to some degree of discretion regarding the "making" process. I've never seen written down anywhere what order you have to do your operations. With that said, if you are busted going down the road with a finished silencer with no paperwork, tha...

Re: .223/5.56 silencer with no legal limitations.

Just use a clipped cone design. I use that for hog eradication, and have killed hundreds, maybe a thousand. I use a lightweight design with only 3 baffles because I'm carrying it around a lot.

Since no restrictions, maybe use aluminum and replace parts as necessary?

Good luck.

Re: Questions from an inexperienced Form 1 builder.

I've built a bunch of cans, and all have been direct thread. I've never had one loosen, and that has been real world night time hunting scenarios, borderline abuse stuff. Qd stuff is cool, and I have some. But it just really seems unnecessary to me. You can make what you need with just a lathe. Buil...

Re: Can Titanium Tube be joined to Stainless Endcaps without threading?

I have come to the conclusion that having carbide inserts is "necessary" for machining titanium is a myth.

I have had fantastic results with good sharp HSS homeade tooling on 6AL4V and grade 9 tube.

Good work! Now chamber it for a 38 Super and get more power! :D "Giggle quiet" and ".38 Super" have NEVER worked in the same sentence, much less the same firearm... You have more powder space in a 38 Super and can load a heavier sptizer type bullet to max subsonic velocities. More energy at the tar...

Capt. beat me to it. Don't do it unless you wan to make things, lots of things! A couple of suppressors, just buy them. If you really want a machine shop, get a mill and a lathe....as much as you can afford. Otherwise, not worth it.

The orientation matters with respect to each baffle (all clips on same side), but it doesn't matter in relation to the firearm.

It's not a silencer part. Could you make a silencer out of it legally with a form 1? Sure. As far as the dimensions of the item, I'm not sure the end cap would have enough meat there for muzzle threads. I'd pass unless I could handle the item first to better determine if suitable.
