I've got a pretty nice Starrett dial indicator and a magnetic base but
I've found that I get good results by using a simple combo square.
I mark a tooth with a magic marker and check it where it would enter
and leave a cut, with the blade run high.
It's fast and simple.
I find that the Unisaw stays put pretty much, once it's been set, as
opposed to the Delta Contractors Saw that I had before, which needed
to be reset maybe once a month, in a shop where it was used maybe
twenty to thirty hours a week.
As always, YMMV.
