Figured it's about time for a radial engine. It'll be compressed air using my ball slave valve arrangement. Operation will be 4-stroke using a 2 lobe, coaxial cam turning at 1:4 ratio to the crankshaft. Here's the beginnings of a concept picture:
I started out rough cutting a hexagon out of 1.25" thick aluminum tool plate with my 4 x 6 band saw. Then used a 1" arbor to chuck it up in my 5C hexagonal block. I used a 2" indexable carbide mill to face off each of the 6 faces.
Wound up with what seems like a respectable hexagon 1.25" thick and minor diameter of 2.443" (Yeah, I over shot the target diameter of 2.500" :-[)
