I knew I should have said "no SDS". :) When I had an ultra-tricked out Scoutmaster setup a few years ago I had it, and found *little* difference. I have very clean AC.
I don't think that's the problem.
I think a Scout rim drive could be killer and is probably the best bet.
(I will never forget a demo of the Teres rim drive at RMAF 07. Took that already stellar table to another level.)
I should probably try a thread first, if that will work.
By the way I tried moving the motor assy farther from the platter tonight and that actually made a difference from the better.
Thanks
