What is the rule of thumb for the heat shield
between the exhaust pipe and the cowling. I have fiberfrax to glue
on and planned on covering it with .016 SS, the pipe is 2 1/2 SS, do I need a
shield 5 inches wide? Thankyou

John, insulation is a good idea but the best way to prevent radiated heat
is to use a heat sheld. The more space you can give it (on BOTH sides) the
better. Feeding a small air bleed in the area to cary off the heat is also a
good idea. The air bleed doesn't have to be big, it just has to keep the air
moving.
