TS Question

[Ross Sutton]

Anyone experience this ? Checked my year old Powermatic 64A for blade to miter slot parallel, I find it is off by 20 thousandts. After I make the proper adjustments and get it within 3 thousandts, I make 3or 4 cuts, run the blade up and down and then recheck with dial guage again, this time it is off 25 thousandts. I don't dare tighten the bolts any more then I did, what else coud cause this?

Thanks in Advance
