Regarding ways to make the motor mount adjustable to permit phase
adjustment, John Freau's electronic phase adjuster makes that completely
unnecessary.  All you need is a small Variac and a motor run capacitor.
For my Teletype motor I used a 2 Amp Variac and a 40uF run cap.  Photos

How did [PHISH] get into the subject line?
