Re: Repairing a scored spindle ?

Would another lathe with a tool post grinder be sufficient for the grinding job?

Finding an Automotive machine shop with a crankshaft grinder who will grind the spindle ,less difficult than grinding a lawn mower crankshaft, then tin the brass bearing with tin solder and pour a babbit bearing overlay on that tinned brass bearing using a mandrel a bit smaller than the finish machined spindle. The result could be a better bearing surface than any lathe has ever enjoyed. That is the way it was done before ball/roller bearings and worked with less vibration, chatter and ran cooler with proper lubrication. Contemplate it !
