You need 90 - around 115 RPM's.

Depends on your preform. my friend who builds machines uses a faster motor with his and they work fine. Highland parks high speed grinder is a lot faster...

If I wanted to make lots of spheres I would have a 100 rpm machine dedicated to coarse grinding, then move to faster machines for the rest of the process.
@shotgunner from the looks of those gearmotors I suggest you use couplers and support the grinding heads with bearings that are a little more heavy duty.

“You preachers of equality, the tyrannomania of impotence clamors thus out of you for equality: your most secret ambitions to be tyrants thus shroud themselves in words of virtue. Aggrieved conceit, repressed envy—perhaps the conceit and envy of your fathers—erupt from you as a flame and as the frenzy of revenge.”

Covington makes a machine at 161rpm and it works wonders. I have used that machine at class.

While I appreciate your opinion, please consider this is a for sale thread and I am trying to pay some bills here.
