Hi, fellow rotary enthusiasts.  I understand that one builder/flyer with

a 13B has used stainless

steel hand railing parts for his exhaust, and that they have held up

well. I think it might be Ed

Anderson?  Does anyone know the thickness of these, where they might be

purchased, and finally,

any possible pictures of them?   I was wondering about the feasability

of making up a set with

short heavy duty stainless steel headers, then attaching with stainless

steel flex exhaust tubing

(to prevent vibration cracks), to the main in the cowling muffler. Any

thoughts/ suggestions are

certaintly welcome.  Thanks in advence for any and all replies.  Paul

You'r correct in that I use the schedule 40  stainless steel pipe Wagner
uses for making railing.  It has worked fine for 256 hours with no
deteroration other than some discoloration.  I have it tapped for two EG
probes and one O2 sensor.  The headers are approx 18" long (one for each
exhaust port) and they extend down approx 8" before making a 90 deg bend to
the rear and exiting the cowling.  I first mocked up the routing of the pipe
with "cheap" mild steel angles and once I got that where I was statisfed and
knew which angles to order I then ordered the sections from RB Wagner.

I then clamped the sections of SS pipe together using "hose clamps" and
carted it off to the welder who did the rest.

I suspect that using PVC pipe might be even easier/cheaper than mild steel.
