I raise my blade to full height and align the blade to the miter slot to within .001 from front to back of the blade using a dial indicator. I check and recheck and tighten and it stays aligned. However, when I lower the blade closer and closer to the table it drifts off alignment all the way to .004 difference from front to back of the blade. Thats when the blade is about 1/2 inch off the table. What can I adjust to compensate for this or should I split the difference between the two readings of full height and low height??? Please help!!!

Kind of splitting hairs aren't you? I'd say that was pretty good if you are measuring off the blade. I can't recall seeing any blades that precise. The proof is in the cut. We had a beam type panel saw in one shop I worked in and we couldn't indicate from the blade because you couldn't get to it so we would read the cut to adjust it. Each time we put on a sharpened blade we had to do this so this should say something about the blades...variation. We would cut a piece of MDF. MDF is nice because you can see the saw marks, especially if you shade it with a pencil. What you want to see is the heel and toe cuts from the blade on each side of the cut piece. Take your miter gauge and cut a piece of MDF. If it's lined up right your should see front and back teeth marks on both pieces. Obviouslt if you see toe marks on the left test piece and heel marks on the right test piece it's off. You can also use this technique on your fence. Who says you need expensive test equipment!
Yep... :)The proof is in the puddin'
