The trick was to increase the input shaft diameter
to 1.500 inch diameter rather than one inch
like Tracy used. A whole raft of benefits came
from that. Not the least of which it was much lower
cost to machine and the joint between sun gear and
shaft was much stronger. Dave Leonard broke one or two early
gear connections.

We also applied some of what we learned on the time
to climb 650HP coupling.

The shaft is off the shelf ground and hardened. Good for the
seal. It can be drilled out with a one inch drill to cut the weight.

Chris Hoskins in NZ is working with the many extended point set screw idea
to substitute for expensive splines.
