Is .035 416ss to thin wall? for 1" .22 can

Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

Is .035 416ss to thin wall? for 1" .22 can

Post by fastfire »

Researching tube thickness for 1" .22 can
Can a .035 416ss tube be threaded and not be a safety issue?
Is this to thin wall?

Thanks

You can research burst pressures here

ETA:
If you are planning to use threads, yes .035" is too thin.

Yes it can be done with a fine pitch thread w/ special construction techniques to handle pressure.
I would use it for monocore construction without threads to allow easy stripping and simpler construction.Where did you find tubing in 416?
The only reason after 243 years the government now wants to disarm you is they intend to do something you would shoot them for!

What about welding at mounting end and threading at muzzle?
Monocore would be a stronger design?

I'm not too sure what thread pitch you intend to use, but even a 40tpi would leave only 0.013"/side.
I generally shave 0.010" from the ID, prior to threading. Just helps the baffles slide in easier.
Are you trying to save weight or money? You're not gaining an appreciable amount of internal volume so it must be one of the two.

Weight. Go Ti or 6061
Money. Go 6061 or the guy you listed has 1"OD x 0.065"Wall for $20/ft.

I'd go to .065 before welding on some special end fittings. Just easier, IMHO.
Besides, w/ rimfire, you're going to want to open and clean it.
Yes, with the monocore you can use the .035 and no need to thread it at all.

Please elaborate; Yes, with the monocore you can use the .035 and no need to thread it at all.
Weld?

You thread the end of the monocore and use a nut on the front end to capture the tube. No threads on the tube itself, and if well fitted to the monocore there's no need for any O-rings. Of course there could be some difficulty slipping the monocore out of the tube for maintenance, but a number of commercial .22LR cans use this layout and seem to work fine. I'd suggest cleaning every couple of hundred shots and using a little lithium grease in the first few chambers to keep it easier to clean.

If you must cut threads 48tpi recessed about .100" and 3/8 or more long will work.Even screws around the perimeter can be used.Mig tig or silver solder would be much stronger cheaper and easier than cutting these threads.
What design,length,host and munitions are planned for this.

Mono core, 6" long and anything from subsonic to high velocity .22 rimfire.

Ruger MKII 4" barrel
10/22 18" barrel
Savage MKII bolt 20" barrel

I will be sending my Form 1 in next week and will post pictures while making it. :D

I used 0.035" wall 1" OD 316 stainless tube for my rimfire can. I welded it up completely. No take down at all. Drop the can in the dip for 24 hours every 5000 or so rounds and your good.

Unless I am missing something, all that tubing is 316.
