I would be further on, but I discovered MUCH too late that a whole batch of the 624ZZ bearings were faulty. Had to disassemble the whole thing, check all the bearings, and replace the faulty ones. The centre race is a few thou too slim, so when you put a washer either side and tighten it up, it binds on the outer race and won’t go round.
Anyone want 60 bearings that won’t go round?
Will fire it up tomorrow, hopefully, if I can find my laptop and get it going.
