I'm looking for a source of 1 1/2" flexible exhaust tubing. Mild steel is
acceptable. I want to use it for a model of the headers of a tuned exhaust
for my 0320 Lycoming engine that I have mounted in my Baby Belle helicopter.
The idea is to have 4 equal length pieces attached to exhaust flanges bolted
to the cylinders, arrange the 4 pieces to intercept the 4-into-1 collector,
coat the tubing with epoxy resin so that the shape is maintained and then
present these pieces to be copied by the exhaust bender.

Aluminum "wrinkle belly" tubing should hold it's shape nicely. This
stuff is a little oversize. Great Plains Aircraft Supply carries this
stuff too, if you want to support an aviation vendor.


I have seen such ducting in paper also which would make epoxying it
into shape easier. Try J.C. Whitney, they used to carry it.
