Ctlphd, Sorry, I failed to distinguish between the single-motor flywheel and the older standalone flywheel. If using thread drive I wouldn't bother with a single-motor flywheel, as it provides no method for adjusting thread tension between the two without resorting to a DIY tensioning pulley similar to ptmconsulting or my custom TNT. With a standalone flywheel the thread tension can be easily adjusted by shifting the flywheel.
I find that with the thread properly tensioned there is no need to give the platter a push at start-up.
