Hi

Saw this on youtube:

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?

You're right, Uffe. He'd have to support it at the ends and run his
own "ways" across to hold that grinder to get a perfectly flat cut.
As his setup works now, it's tracking any wear or curvature of the
ways, but it is offset a bit by the sled.
