atmasphere's (Ralph's) point about tension on the spindle with the belt pulling to one side was addressed by one table I'm aware of. I owned an original Well Tempered TurnTable and the spindle well had five contact bearing points. Two were inside the well (maybe 45 degrees apart?) near the top nearest the belt position, two more were nearer the bottom of the well and opposite position of the upper two, the fifth was at the bottom of the well in the normal position. This way the tension applied by the belt held the spinal shaft against the upper two bearings while a vertical position was maintained by the two opposite bearings lower in the well. The spindle shaft could wobble within the well until the belt was installed to bring it vertical with pressure on all five bearings. I don't know if any other manufacturer adopted this simple but ingenious solution to retaining a vertical spindle shaft?
Direct Drive vs. Idler Drive vs. Belt drive
I'd like to know your thoughts on the strengths and weaknesses of each drive system. I can see that direct drive is more in vogue over the last few years but is it superior to the other drive systems? I've had first-hand experiences with two out of the three drive systems but looking to learn more.
