How Flat is Flat for a 6" Joiner Top

[Wayne Boian]

Just finished rebuilding and painting my old Jet 6" Joiner and started putting it back together. On the infeed table there are two spots where light will shine under a straight edge. I think about 2 to 3 thous low, or about as thick as a piece of paper.

Don't think they will be a problem, but it did make me wonder what the spec should be for being flat or parallel end to end.

Any one know?

Thanks Wayne

Some small depressions are less of an issue, but the entire surface of your tables should be level/flat and the two tables need to be parallel in all axis.
