Re: combo machines 3 in 1 lathes and mills

You won't see manual combination machines in professional shops. There's a reason. IMO, they should be avoided entirely. The only things they excel at are wasting time and causing frustration. Some folks liken them to CNC millturns. They aren't remotely close. Agree with ECCO. Run Forrest run.

What if I wanted to do something like have a tactical innovations fake silencer hogged out for solovent trap k baffels and have an end cap threaded in?

I can probably do that for you. I would need a copy of your form 1.

Re: Advice plz: 5.56 end cap hole size, engraving location

A Chinese, Aluminum, monocore is a horrible choice, horrible. Regardless of your first go'round, don't do it. Exit bore relies on design, but stay >.080in over caliber. You can engrave whatever you want. Some do endcap, some the mount, most do the tube. Placement on tube near midle or closer to mou...

What type of baffles and how are they clipped? Single or double clip?

Re: Form 1 questions

Low pressure configurations should be different from high pressure configurations both in type of baffle, length and baffle spacing. You would be much happier designing two suppressors, each dedicated to the host rifle.

Re: end cap strike, 9mm threaded can

Something is way off. I'm guessing it's an alignment problem. I would order a proper size alignment rod from McMaster-Carr and check that the suppressor is in line with the rifle bore.

Re: First Form1 - .22lr

A 1" can will suppress a 22lr well, but for .223 you need a 1'5" tube with stainless steel or titanium internals.

Re: How does it look (in progress)

If you have access to a milling machine and a rotary table you might want to consider the undercut as shown in the photo. Ignore the integrated muzzle brake as this build is for a 17 hornet/hmr. You can do the cut on the lathe but when I tried plunging this deep chatter always gave me a fit. I used ...

Form 1 Question

I have a trust which Was created when I purchased my first suppressor. Since that time I now have a Class 01 FFL. I am going to be applying for five (5) form 1's in order to build five new cans. My question is should I list the truss on the paperwork or use my FFL number?

Re: First form-1. How much clearance for .22lr ?

Curious then. Has anyone tried progressively larger bores? Say I have 8 baffles and the first is bored 0.250 and each successive baffle is .005 larger making the end cap bore 0.29 in diameter. Taking it even further, if each successive bore was .010 bigger than the last, then the exit bore would be ...

Re: First form-1. How much clearance for .22lr ?

I read that .06 is the drill size over bullet size to allow for misalignment using a drill press. So what if one is using a tool room lathe. Baffle to wall clearance is .002. Punch a starter hole with a center drill, drill slightly undersize final hole size and ream to finish. As an example I routin...
