Scraping and planing...

My first thought was “Great idea!”

My second thought, though, is I wonder if you are running the risk of “unsquaring” your square?

Agree w/Charlie. If it is a cheapo square, or out of square, I would think you are onto an easy solution.

Why not just tack a thin piece to your workbench top. Cheap and infinitely adjustable.

I do a similar thing – but I just use a scrap piece of thinly sliced cutoff (that I usually have from resawing this or that)

A vertically adjustable stop across one end of the bench?

Charlie, as a followup to your comment I changed the config and tested for square after every use. As you can see I have secured both legs which should take most of the stress off of the square’s 90 degree angle. After each use I compared the carpenter square to my Incra square and my Starrett. I am happy to report no change or damage to the carpenter square.
