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.

I'm sure that the ways will look good when you grind like this guy does.
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?
