Recently got a Powermatic PM2000 cabinet saw. Yesterday I set the miter
slot to blade and miter slot to fence parallel adjustments using a dial
indicator. I was able to get both to within .002". So far so good. Today,
I've place the blade at 45 deg., and the measurement from the front of the
blade to the rear is +.016". I understand this indicates the table is
sloping at the front side & needs to be shimmed. OK, I get that. HOWEVER,
if I loosen the 2 bolts on the front side of the table & lift, the error
INCREASES. If I loosen the 2 bolts on the REAR SIDE of the table & lift,
the error ALSO INCREASES. How an this be??? Any suggestions appreciated.

TIA

Dan
