Re: Brass Tubing Exhaust?
I'm afraid you're going to have problems bending that brass. Even the old packed sand trick might not keep it from kinking. There is/was a product called Cerobend that might work. It was a low temp lead based alloy that melted at about 200 degrees. You fill the tubing with it in a molten state and allow it to cool then bend the tubing and then heat it in hot water and the Cerobend would run out leaving a good, kink free bend.
A member posted a link to Cerobend a while back but I can't find it now. Maybe he will see this and repost where it can be obtained. Good luck.
