I just purchased a used smithy granite from farm that had been sitting in outbuilding for some time. The machine had a shredded nylon bevel gear to the mill attachment. I took the mill off and noticed a lot of sand debris in the headstock. The gears don’t look too bad but the spindle bearings are loose as a goose. I want to go ahead and replace the spindle bearings while I have it apart. I would rather purchase the bearing from somewhere other than smithy because they want a premium price for theirs. Their website only list them by part number and not the size. Does anybody know what size taper bearing they use on the smithy granite?
