Subject: Powermatic 66 TS advice?

I've noticed an interesting "feature" of my Powermatic 66 tablesaw and
am wondering if any other 66 owners experience the same thing.

When I raise the blade, it moves slightly to the left. When I lower it,
it moves back toward the right. The blade is set to vertical, and a look
at the trunnion doesn't suggest any reason why this is happening. The
total lateral movement is about .020 over the range of blade height. As
a result, the slots of sliding tables and jigs get enlarged as I use
them with different blade heights.

Any ideas would sure be appreciated.

I couldn't even guess at why this would happen and went to my own PM66 just
now.  There is absolutely NO variation in the blade's lateral relationship to
the sides of the saw through its full range.  

Here are some thoughts-

Is the blade warped or the shaft bent?

Is there some crud between the blade and the washer that is cocking the blade?

Is the table parallel to the spindle? 

Has a trunion bearing been trashed?

One of the "sacred" things in a TS is that the blade is at right angles to the
top and retains its position despite being adjusted up or down.

FWIW- you might read my review of Ed Bennet's Table Saw Aligning tool in my
ftp site.

file.
