Motor heat and vibration

Hi all,

I'm still having significant problems with the motor points sticking. I bought some new US made capacitors and that didn't seem to help much. I'm currently looking for some 15,000 ohm/2 watt resistors to put on the caps. I hear this should help a lot. Has anyone here tried this?

I also got an email from a fellow that suggested using a MOV and capacitor combo across the motor points to help dissapate the surge. Has any one tried that?

The point of the post though, my lathe motor gets pretty warm. I'm not too worried but with my other motor problems I'm looking out for other potential faliures. I can put my hand on the motor can for about 3-5 seconds before it gets too hot and I yank my hand away. I haven't run the mill enough to compare. Any thoughts on how hot is too hot?

It also seems like the lathe motor vibrates a LOT more than the mill motor. Often I fire up the lathe motor and it makes kind of a nasty vibrating sound that goes away if I push on the motor can, but touching the stand, I can still feel a significant vibration. That said, the problem is intermitent. I thought maybe it was just vibrating against the mounting pin so I hammered in a little wedge of wood to no effect. Anyone else have this vibration issue?

thanks,

DaHui
