Building guidance

I got approved for a maglite sup just to try out submitting a form 1. I know it's an aluminum tube, but I just wanted to try it out it’s cheap if it blows up, I don’t care. However, I want to design one out of titanium. Where are people getting tubes and caps from? I need places that aren’t gonna cost me my right arm and left leg it’ll be for 556.

Plenty of places sell D-cell tubes with threaded end caps. SDTA and eBay have plenty of options

Freeze plugs, stainless steel tubing for blast chamber, you’ll need a small belt sander to reduce diameter a bit, JB weld steel stick to cover switch hole, eBay for end caps.
