Space for the taperlock hubs mainly. I am resigned to warming the assembly up and splitting it back into 2 pieces, mounting each one at a time on the 20mm mandrel, using nuts on the far end of the draw bolts for the smaller pulley, since I drilled thru the smaller blank with a body clearance drill. The intention was to keep the smaller pulley from spinning if the taper is off, and it is slightly. But until the sawbones types try to fix me, not much of anything is going to get done. As of this mornings exam, they have to clear some xrays and an MRI with my Plan F & let me know where/when to show up. When he asked my how bad I hurt on a scale of 1-10, I said 22. :) That got a chuckle and the mood lightened up.
