I want to build a Flame-Licker, model engine.
What metals will work well for:
Cylinder
Piston
Cam/Follower
Valves
Cylinder: Can stainless-steel, brass, bronze, steel, be used? Will these materials gall?
Piston: Machinable Graphite, oil-impregnated bronze bushings, stainless-steel? Must I use a ring, or, O-ring?
Valves: Steel, bronze, graphite? Valve is exposed directly to the flame that enters the cylinder.
Cam/Follower: Hardened/soft-steel, bronze, brass?
All other parts will be fabricated from materials on hand, except crankshaft.
If possible, suggest best combinations. My concern are different, or incompatible coefficients of expansion, galling, and piston sealing/blow-by as engine heats up to operating temps.
Thanks for the help.
