I finally got my VFD so that I can run my mill now. I powered it up this evening; when I bought it I knew there were some issues with the head (it's noisy). Its a bit noisier than I remembered, so, in order to keep my neighbors happy I am going to have to dig in and figure out what the problem is. I did clamp up a 3/4" piece of drill rod in a collet and put a DTI on it. Pushing on the bar there was no measurable movement, turning the spindle by hand in neutral I could not measure any runout (well, maybe 1/4 div on a 0.5 though dti), so I don't think it is the bearings.
I'm thinking my next step is to remove the motor and top part of the head. I am hoping somebody has a link to a tutorial on dismantling a variable speed head. Barring that, if anyone has done this, where do I start? I know the reeves drive creates tension on the belt, so should I wind the speed up to high and then just pull the motor bolts, or is the another order to do things?
