I am interested and reading everything at least times not once.
I also looked up the instructions on how to mount the fence on a Unisaw.
There are several almost fool proof ways to get where your holes need to be without measuring.
One is called transfer punches.
Another is to use a long template made from painters tape or cardboard and a ball peen hammer.
Get the stuff lined up where you want it and make the first hole with the ball end of the hammer put a bolt in it and make the other hole the same way.
I have used the last method to make huge gaskets for pump housings and inspection covers on giant industrial engines.
Cut the whole gasket out with a ball peen hammer.
