Well I just found some aluminum tubing in the scrap pile. Don't know if it's the right size or what grade it is but it looks close and I need to try to bend it now. My friend has a tubing bender so maybe get that done this next week. It will be nice if I can just alumiweld it. If this works out, I want to try to make a mousse can pipe for one of these asp 46 to see what it will do.
