Grinding lathe bed.
Ways should be scraped if bad. Mechanical scraping across
the bed. What he is doing is grinding down one deeper and deeper. The angle of it from the other changes as he goes on for more. Grinding would be ok if the grinder was held up off the work surface on a precision way that would not change. My 1952 dated ways continue to have deep oil veins and the cost of having the ways chromed or made out of a chrome alloy - they are in great shape and are without wear. It was a light duty lathe but used through the years. I keep way oil on it, Dad put 30 weight (not ase 30 ). I noticed the main bearing felts were stiff when I started using it several years ago - I suspect the oil had varnished over them. I put 30 weight on it and kept the pots full. Now the pots run and I suspect the felts are soaking nicely. I use mine in spurts - on the last big project of building an auto-reset target system I was turning rods and boring bars.

But how about saddle wear? (don't know how to spell it :-( ) As far as I can see there is no way that you or me can remove saddle wear grinding a bed like this only add more sway to the bed. Am I right or wrong on this? |
