The thing is, it doesn't even matter right now, so long as the 'gear' aspect is the same.@Sep 29 2005, 09:35 AM
If the gear is part of the shaft, my theory is that they cut just enough of the shaft so that it would be held in place by the graflex clamp.Â
And remember it looks very much as though the prop 'gear' was shortened from a longer length--i.e. longer than 1.5 "
That's true. If the gear looks like the starter disengage shaft, where the splines are carved out of the shaft, then that would make total sense. Cut off the gear, cut it down to size, grind off some of the teeth to get down to round stock and voila.
P.S. here's a page with som really great pics of the RR nene turbo engine. There's some really good cutaway drawing as well as a really good pic og the IG88 head http://www.gasturbineowners.com/nene_jet.htm
