Hi everyone, I've missed the forum, and hoping to spend more time here starting now. I'm teaching at a big facility that has several lathes, one of which is a Jet 1236. I'm quite familiar with this model, since I own an older version that has been more than a bit of a pain. The lathe in question, at BARN, has twice stopped changing speed because the KEY has tipped up a hair and prevented the spring-controlled pulley from moving with the shift lever (Reeves drive). Has anyone ever encountered this problem before? Suggestions?
