Hey everyone! I just bought an older (green model) Rikon 70-100 as my first mini lathe. Unfortunately it has an issue I need to resolve. I knew this when I bought it, but hoping to get some advice before I dive in.
When the lathe spun up to speed it had a bad vibration and noise. We isolated the motor (ran it without the belt) and it was fine. So it must be coming from the headstock assembly.
I grabbed the pulley side of the spindle shaft and notice it could move up and down slightly. I’m assuming this is the issue and that it’s supposed to be firmly seated in the bearing.
My assumption was it’s either a worn out spindle shaft or bearing. But when I called Rikon tech support an overseas fellow said it was the wave washer (part 70-100-10).
Any input on this? Anyone have experience with a wobbly spindle shaft and can give some first hand knowledge?
The unit was “well used” so I don’t doubt some things could be worn out. But before I jump in and start ordering parts I’d love to get your opinions. The whole wave washer thing doesn’t make sense to me as I’m not sure how a washer would tighten up the fit of a shaft in the bearing.
