Hello all. I am going to build a supressor on a form 1. It will be going on my 300WM. I am doing a little research on design before I submit my form to the atf. I am really considering building this one from titanium. Can anyone give me an idea of wall thickness used in commercial cans. I am leaning twards a larger blast chamber that covers part of the barrel to keep the legenth down. I am also thinking about making it to fit a .338 as I plan on building one of those next. Any info is appreciated. Thanks.
 
Re: titanium tube thickness question

It will hard or impossible to find titanium tube in the dia, grade and thickness you will need. I built a suppressor with 1" dia. titanium hydraulic tube for a 22 rim-fire. Titanium is a difficult metal to work with, IMO it is not worth the extra PITA . Alloy steel tube will be stronger, easier to work with and easy to find. 2" x .120 wall 4130 aircraft tube machines and welds very well. Welded on ends add a lot of strength to the suppressor. I wish you well on your suppressor project.

If its gonna be threaded caps and built along the lines of the Tac-16 then I'd use .087" wall Ti.

316 is alot easier to work with especisaly if you have a little expericance with a TIG welded
 
Re: titanium tube thickness question

I hope you are very sound in machining and welding technologies for Ti. It is NOT an easy metal to work with. In fact most guys that are welders..... and work with Ti are some of the highest paid laborers in metal working. We have a guy that is 62 years old that works in our mechanical shop, he has tried to help me with some Ti roofs for my UTV that I race. I needed light but super strong. Moral of my story is...... after 40+ years of working with metals and welding. We could not get Ti to do what we wanted. Being that it's not cheap, we opted for another metal.

I would say if you do use it, and plan on using it for a 338 - go with 1.75" diameter and 10" in length. You will be shocked the amount of baffles you can stack in that. Also do yourself a favor..... Machine the tube with the exit end cap part of the outer tube. Then machine your baffle stack to slide into the main tube and weld the back shut. The baffle stack should have the female end cap (the part that threads on your barrel).
 
Re: titanium tube thickness question

If you are going to run this on a 338 you need a minimum of 1.625 OD and .090 wall thickness in Ti. I run this on my 338 cans with great success.

If you are a good machinist it won't be difficult. If you don't have much experience with Ti it will challenge you.
 
Re: titanium tube thickness question

Thanks guys. I have the expirence in machining. As for welding, I have a fancy tig welder but in this case I will pay my welding instructor to do it. He owns an aerospace welding lab that develops welding procedures for that industry. He is unbelievebly good. I am crusing the websites and checking out designs. I am not sure yet how it will come together but I need to come up with a basic design so I can settle on a legenth for the form 1. I am thinking I will thread and weld the rear end and just thread the front so I can remove the baffles as needed for whatever may come up.
I have a M4-2000 on my full auto M4. It is not too big but it is heavy for it's size compared to my CAC9 on my mac 10. Of course it is aluminum. I just want to keep it light as I will be packing it around the mountains at the tactical shoots. Thanks for the input everyone.

Yes titanium is a real challenge. But as long as you have lots of material it can be fun as well.
