1. Is the nut reverse threaded such that actually RUNNING the saw tightens
the nut? If I was building a saw without a way to grab the shaft, that's the

Isn't this the usual design? My cabinet saw (which uses two wrenches)
is set up so the startup torque tends to tighten the nut.

My question exactly... My ancient Rockwell Beaver is set up like this.

I thought they all were.
