Not a machinist, 1st time lathe owner. I bought a 15x54 cincinatti tray-top, non-hydrashift, lathe. According to the manual, it is an "all electric drive verses the clutch drive model" I witnessed it run off of the rotary phase converter at the previous owners shop. He mentioned "in-consistent" starting when engaging the head stock spindle start/stop lever, but it functioned at his shop. I am now experiencing the inconsistent starting issue. The electrical appears correct, but i (and a machinist friend of mine) have only been able to get the spindle to turn on 2 occasions. The spindle will turn about 1/16 turn in forward and reverse every time, but has only turned on fully twice. I assume there is switch or adjustment to be made. I looked at "clutch adjustments" but my model is the all "electric model" according to the manual. There is also a filter located in the headstock gear area that is also actuated by the start rod, although this is not a hydra shift model. The spindle rotates in neutral by hand and you can feel the gears engage when changing speeds on the transmission while it is off. Where do i start? Edit: Added some pics of the drum switch and oil filter.
