I am not going into the belt drive, direct drive, idler drive argument. That's for those with nothing better to do.

But the way your belt drive TT was working was actually the proper way. You really don't want a total and full contact with whatever belt you choose to use, at least with a TT. As a matter of fact, the ungodly expensive TT by Lloyd Walker cannot start on its own just turning on the motor drive. The belt is so loose that the pulley on the motor will just turn and the platter alone is ultra heavy(about 50lbs.). All it is there for is to keep the momentum going once you push the platter as a start. With the motor turning you can actually hold the platter still and the motor will just spin without any really loss to the RPM's of the motor. It gives very gently shoves to the very heavy platter to keep the speed dead on. There is almost no resistance at all on the platter once the air is applied to the bearing. With no belt you can give the platter a small turn and it will spin on its own for about five minutes with minimal speed loss. The weight of the platter forms enough inertia to just need very light touches to keep the speed constant. Only issue with that system is that each time you shut it down and then turn it on you have to readjust the speed for a while until you get it right. But once you get it right it is golden. It's almost like nothing is turning the platter.
