A quick and accurate method to square your miter gauge:

I know I have started threads in the past that describe this method,
but I finally put it in a video. If a picture speaks a thousand
words... Yeah, I know, there are dozens of methods for doing this
and that the 'old dogs' that use a square pushed against the blade and
the miter gauge will never change but...

Brian, glare and insufficient contrast on that vid make it so that I
cannot see the face or needle on the dial indicator, even in the inset
shots, even with my computer glasses on.

yes, that was a problem. It's not really glare, but the quality of
the camera. When I zoomed in tight the dial face was clear, but my
gauge and square was out of frame. I either needed a high def camera
or a second camera that was zoomed in. On my computer I CAN see the
dial when it is moving. Otherwise it was very difficult to see. I did
my best with what I have.

Better camera won't help the particular problem. If you watch your
video you'll see that the dial on the TS-aligner off to the left is much
clearer than the dial indicator that you are using. Also if you look
closely at your hands you'll see a lot of white areas--what
photographers call "blown highlights". If your camera has exposure
control try adjusting it to darken the image a bit and I think it will
be clearer. Alternatively, try playing with the positions of your
lights to put the light where you want it and at the angle you want it.
