Has any one scraped in there headstock bearings when rebuilding there 9' south bend? I know how I have done centerless grinder bearings years ago, but they are more critical than a lathe. I moved this post from the south bend site was not getting any response. Also how much ware in the bed before it justifies scraping ( in thousands)?​

I've never touched the spindle or the cast iron bearings on my 9" SBL. Last time I tore it down, they looked great. It's time to doe it again, but I have two other lathes down that I need to get running before messing with my 9".

I've scraped in the spindle bearings on a old Lehmann Lathe I owned several years ago. A lot of work!

My 9" has bronze bearings in it,just thinking it would have more oil pockets

Leave them alone. Unless they have excessive wear from lack of lubrication. Then, they may have to be replaced. Scraping a worn bearing can only work and be done if they are split and the bearing caps are split, too.
