I have had my Table Saw for almost a year now. It is a Grizzly 1023SL and I am very satisfied with it. When I change from 45% to 90% using my Incra jig for cross cuts, I have trouble getting it square or at 45%. I can get within a 32nd or 64th, but not completely accurate. I check it by taking a square piece of quarter inch ply, numbering the sides 1 through 4. I then cut a bit off of each of the sides and finish by going back to 1 and cutting a 1/2 inch or so piece off. If I do it correctly, using my digital calipers, the width of the piece I cut off should be the same top and bottom. That's the rub, it is usually off at least a 64th.
I guess I am asking, what is the best way to achieve this? I can get vertical 90 degrees and vertical 45 degrees using the digital gauge I have, but it does not work for horizontal. Does any of this make sense? If not, I will draw a diagram and try again.
