The magnetic chuck was clamped extremely tightly, and is now off the table.
The table was removed, the rollers and retainers cleaned, a light lubricant applied and the table re-fitted.
Rolls very nicely.
My metrology is a bit challenged at the moment, but the table surface does appear to be high at the ends.
What would be an acceptable standard of flatness, concave or convex, for the table on a grinder like this ?
Thanks in advance for any advice,
