I was wondering if a metal tube that had fins on the outside could remove sufficient heat to protect the tubing. We had a rather large shop compressor where I work that had such a pipe. It was a two stage compressor where one piston fed a second piston to get the pressure up. The cooling pipe kept the second piston from heat damage and the flywheel doubled as a fan. The finned tube sat in the draft from the flywheel for forced cooling.

Al,
I am not mech eng either. I have brains for it, but don't have the required education
.
VIAIR 250C-IG Compressor is a good option, but at extra 4 lbs weight and extra cost it may not work for all teams.
I haven't done the math, but I am positive that heat sink I am designing would weigh less than 4 lbs.
I haven't learned enough CAD to properly heat stress test , which leaves making it and testing as the only option.
