I got this old bridgeport mill a few weeks ago and I'm thinking about having the table top ground to take out the very many dings,dents, nicks, and drill holes, about .030 should take care of almost all of it. Right now I'm in the middle of cleaning and rebuilding all of the movements X,Y&Z replacing bearings,knee gears, and repainting. For its age 1957, its not in too bad of shape just lots of old grease and grime and the table top is horrendous. once I get it back together I'll put an indicator on it and see how true the table is before I decide to grind or not.
I know conventional wisdom says you have to have all the ways scraped in if you clean up the table top but I'm sure many tables have been reground with out doing all the scraping and suffered no real issues.
Who has had success grinding table top only and not having all the ways scraped?
