Re: Help with lathe, 13x36 Clausing

I think your theory about the damage is correct: sounds like it was dropped. That can cause some more significant damage in several areas. I don't think the drop explains the power feed issue, though. It's possible it happened that way, but the "dead spot" sounds like several broken teeth on a miter...

Re: Aerogel In a Suppressor? Anyone tried?

:idea: It might be interesting to put it on the outside of the tube. It would contribute some sound dampening properties, and probably protect you from getting burned by touching a hot can. Plus, it would make the suppressor look all blurry and ethereal. :lol:

Re: Aerogel In a Suppressor? Anyone tried?

There are several reasons using it that way wouldn't work. Aerogel is relatively fragile, I doubt it would have the compression strength to hold up to the blast. Air does not move through it, so filling space with aerogel would effectively just reduce the volume of the suppressor.

Re: Wellrod SOE WW2 pistol/silencer

I've never quite understood why nobody makes a modern interpretation of the Welrod. I've actually thought about making a vaguely Welrod-inspired bolt-action 22 pistol out of a Savage MKII or something. Maybe someday I'll make a proper replica in 9mm. That is a fantastic video. I wish I could get a h...

Re: 3D Printing of 22LR supressor

Would you make a threaded insert, to be molded into the print, for the muzzle threading? I guess, if T.I.R. is minimal, plastic threads may be enough for 22, no? With a good printer you could print undersized threads then run a tap through it. That should keep it in place well enough. I'd give the ...

Re: Efficient/economical alternatives to Form 1?

Wasn't sure about how easy it is to get your personal collection out. It's already "out". The form 4 process is a tax on transfers. If you make NFA items as an FFL, and then stop being an FFL, you already own the items so no transfer has occurred. You retain ownership, ATF does not pass go or colle...

Re: 22-250 silencer

22-250 is very similar, as far as suppressor design is concerned, to 308. 60-degree cone baffles in a 1.5-inch tube would be the typical choice. There are indeed a lot of car parts that could be machined into baffles and end caps if that makes sourcing your metal easier, but I wouldn't want to try e...

Re: New lathe purchase, is this enough?

Are they as addictive as suppressors? In my experience, generally yes. However, unlike suppressors, lathes tend to become less addictive as you acquire machines of higher quality and mass. For example, my first lathe was an 11" made by Sidney in the roaring 20's, originally for use with a lineshaft...

Re: Threads for caps

As fishman said, 24, 28 and 32 TPI threads are common. Around 0.75 to 1.0 mm pitch would be good if you're into that sort of thing. You're right, there won't be a standard size that works right. Just pick a pitch, and make the minor diameter the same or a few thousandths larger than your tube's ID. ...

Re: Synthetic & Natural Diamond Turning Tools and Inserts

The biggest problem with diamond is that it really doesn't do well on ferreous materials.

Re: Suppressor mounting

You could even indicate the pitch diameter by setting the lathe's lead screw as if to cut the same pitch as the muzzle threads, and using a test indicator with a very small contact point mounted to the carriage and carefully set to read on the pitch of the threads. Alternatively, after machining the...

Re: "LIVE TOOLING" on my old atlas lathe

I thought about doing this a while back. I was going to use a Sherline mini-mill spindle. If your lathe has a very slow back gear speed, you could use this setup for threadmilling; cut your threads in one or two passes and get some reasonable surface speed for 1/2-28 threads.

It really is dramatically better than 304 and 316. It has more than double the yield strength. One failure mode of baffles that I...
