Now why I never considered flipping the darn thing over is beyond me !
Your right, a comparison and corresponding adjustment would do the trick.

I stopped short of using my current Framing square when the pressed in
markings made my Indicator give constantly inaccurate readings as it
chattered along.

What I should do is find a square made out of something that actually
looks like steel ( if that is possible ) and send it out for skimming
both edges square. If their machine is off ( and it could be..) then I
could at least flip it over and do as you suggest.

Thanks for the time you took to answer !
