I'll pose my question again...a little differently this time:
What is the maximum acceptable error for a table saw fence? Mine varies about fifteen thousandths of an inch from front to back. Is that too much, considering that a Forrest Woodworker II blade has a total runout of around
+/- .001 inch?The problem is not linear, so loosening the T-square bolts, aligning the fence and re-tightening the bolts won't solve it. That's already been done. The problem is that the face is not straight. At about 2 inches from the front edge of the table and at approximately the centerline of the arbor, my dial indicator reads zero. Between those points, the fence runs out .003-.004 inch in one direction. At the ends, it varies from about .007" in one direction to about .008" in the other.
Is this a problem? If so, how can I solve it?
The saw is old but works well and I have no plans to replace it. I'm considering investing in an aftermarket fence but that costs a few bucks and I want to see if the original fence is salvagable first.
