Thank You. I worked on it during lunch. I used some very thin galvanized metal, and formed the oval. For the piping, I used the metal stem of a marking flag we use to locate the sprinkler heads before doing any field work. Just the right size, and pre rusted. To do the ends, I used gray urethane caulking, and stuck the pre fabricated piping into the soft urethane. When I got home, I weathered the muffler. No need to do the piping. I'm going to try some gears, using the same process as the saw blades.

The old addage is you can put enamel over lacquer, but not lacquer over enamel. Go to the auto paint store with your problems they have the answers. We used lacquer over old enamel, but dusted it on so it would not lift the enamel.  The new paints are great if you know how to use them, not only that but the paint store just might be able to mix your color and put it in a spray can for you.   Jack Tylenda

Jack, 

The problem with the paint is that it doesn't adhere well to urethane caulking. That's what I used to fill the ends. Also, for some reason, the Rustoleum red oxide primer doesn't come out in as fine a mist as the other sprays I used, no matter how far back I hold the can. I'm going to get a different brand. I might even pull out my Harbor Freight air brush that I bought almost two years ago and never used yet.

Needs a lot more rust. I'd suggest gnarling up the end of the pipe that would attach to the exhaust manifold, so it looks like it rusted through.

Yeah, me too. It was yesterday!
