Just scored a couple off eBay.  Heat treating the cranks and replacing the glo heads with Doug Galbreath,s Nelson plug conversions.

Any recommendations as to nitro limits, prop sizes, etc.? Huh

I've already got yours Dan Grin

Dean, what is your heat treating protocol. I have 2 Hornets, both destined for Nostalgia use. I'm aware that the Hornet rods are fairly weak, but hadn't heard much if anything about a propensity for breaking crankshafts...........

Get wive/children diverted elsewhere.

Preheat oven to 450 degrees.  Put crank in pyrex or other oven-safe non-metal dish.  "Cook" crank for at least an hour.  Turn oven off, and let cool off overnight.  DO NOT OPEN THE OVEN DOOR AT ANY TIME DURING THE PROCESS.

Standard procedure on Tee Dee's.

Aah a fairly standard normalisation procedure then. I've done it on Silver Swallow diesels in the past
