Repairing crushed header / building a pipe

When it glows take a hammer and tap around the edge of the dent. This will help the dent pop out. I worked at it for 10 minutes or so heating and tapping.

The dent came out, all except a very slight depression. It's barely noticeable.

nice

I had to grind out out all the bronze because you can't TIG over it. These pipes are gone where they connected. I will probably have to shorten the primaries another inch...

Here's a picture of the new collector, merge bullets and muffler core. I yet have to order teh tubing for the tail pipe. Wanna see if I can get the collector on first.

An industrial supply like McMasterCarr or Grainger.

What your doing is pretty cool. Also should be alot cheaper than buying a new pipe.

anybody ever seen expansion chambers made by sealing the ends of the sheetmetal design and putting 1000psi through the metal until it is round? I thought it was pretty interesting

Thanks Jordan. I don't know about cheaper, but it will be mine. I like making things myself.

Yeah I've seen hydroforming. Really cool stuff. That's how they make those swoopy Magni pipes on the old MV's too. Here's a guy doing some in his backyard with a pressure washer. Not the nicest work but the process is the same as a pro job. Cut the shape out of two sheets, weld seams, weld in a valve, blow her up and grind/finish seams.

You can get any size ball bearing on Ebay as well. I was buying them, along with some large neodymium magnets, to remove dents in some saxophones last year.
