Rich,
No, it's my favorite gear, but this one needed a Walschearts and I've
never done one before so it will be a learning experince (one hopes).

There is a hefty boss and only a slight force is needed to lock the
taper, far below what might damage the wheel. Possibly the most difficult
part? Turning the taper so that the crankpin neither sinks too far in nor
stands too proud of the wheel hub face. I haven't done the math on how
much change in engagement distance a .001" increment on diameter will make
in a 6 degree (included angle) taper.
