Stainless tubing question....

[rqlasl]

I am getting ready to do my next form 1 can and have a question.
I am going to make the can for primarily my Sar-1 in 7.62x39 but I also want to put it on my 30.06.
So here is the question......1.750 diameter .060 wall 304 seamless tubing. Can it take the pressure from the 30.06?
Thank you for any advice.

I would say its fine, I like to use .065 wall but wouldn't hesitate for a bolt gun with those specs.

Sounds good as long as the length is sufficient.

I used .o65 on my 50bmg can. (I have thick spacers to help with the pressure) and it is fine.

If you have any doubt about the seamless part, make it from solid and you will know there`s no seam!

I wasnt worried about the seamless....I just figured I'd mention it....But its always good to look at all possibilities.
The overall lenght is going to be about 11 inches with about 4 inches over the barrel.
My 1st can was a monolithic style so I never thought about spacers....
It would totally suck having to bore out a piece of 1.750 diameter x 11' 304 ss on my 6 inch atlas!!
I'm leaning towards a stepped cone design...Any suggestions on spacing?

Why not use seamless tubing for spacers? Do it all the time... Just turn it a little thinner to have a perfect fit for the ID of your tube.

The more I think about it I might just do stepped cones and spacers, and weld the whole thing together. I've always been a fan of over engineering everything I make.

Nothing wrong with some over-engineering, better safe than sorry, right?

but then you won't have any silencer eruption photo's to add to the collection

That is true but most Form1 kabooms don't make it online due to embarassment, but people proudly show off when a manufacturers can blows!

With that in mind I change my mind and say that .035 will be plenty thick for a short barrel 30.06 (just kidding)

Nice!....But until they strart making tubes from rolled and fusion welded .010 animantium shim stock.....I'll err on the side caution!

I have seen a 22lr tube that was .030 thick, was threaded I believe 48tpi on the endcaps!

[Bowen1911]

aren't the kodiak and essence tubes super thin?

with the pressures a 22 LR sees, stainless shouldn't need to be that thick at all.

[rqlasl]

48tpi is a mighty fine thread......sounds like a crossthread waiting to happen if your not careful.....I picked up the tube for the spacers today 1.750 od 304 ss....So they're will be a combined wall of .120 with the spacers and can wall...better safe than a celebrity for blowing up a can!

Hi,

SRM: That’s why 0.065 is for you: No need for redoing (kidding as usual) !

I also like what jimmym40a2 says: Use spacers thickness to give some help. For those very large Calibers.

Or (for very large Calibers) start on 1/8 and remove s--t where it’s not needed (CFD helps a lot on that).

Best,

Paul

Maybe it was 42, there was so many hreads on it that it felt almost smooth!

Was NOT a take apart can till I got done with it, ended up sealing it back up because ownever was scared to screw up the threading on it!
