I have an older Powermatic 66 Table saw. It's always been very accurate and has never needed too much for maintenance or tuning. I just ran into something that has me puzzled and not sure if it is indicative of a problem or not.
I was tilting the blade on the saw last week for a 45* cut. When I do this, I use an electric block digital measuring gauge to set the blade angle rather than the gauge on the saw. I usually raise the blade to height, tilt the blade to the required angle with the gauge attached to the blade and then make my cut . Since I've recently made a zero clearance TS insert for 45* cuts, this time I set the angle then started to lower the blade below the surface when I noticed the angle of the blade was changing as I lowered the blade? If I set the angle to 90* I can lower and raise the blade without the angle changing but when it is at 45*, there is definitely a change.
Is this normal? Once the blade angle is set to an angle other than 90*, should the height adjustment work without changing the angle of cut? Anyone know if this is normal or indicates I have something out of whack?
Let me know, thanks in advance.
