Hi,

I was trying to purchase a descent Double square and I seem to be having some issues with tool quality. I have gotten 2 Lee Valley units and when I push adjustable square cleanly to either end and tighten knurled knob and then test the square against my other squares, they are not showing a clean 90 degrees. I returned the Lee Valley square and then purchased a Starrett 13A Double Square (which was about twice the price of the Lee Valley squares) and the same issue happened.

I compared the Double square against my Starrett combo square, a fixed engineering square and both of my Woodpecker fixed squares - and all are off by ~1/32nd of an inch. So I've returned the Starrett now.

When I compare my other squares against one another they are fine - no gaps.

Is not possible to get an accurate Double square? Perhaps I am not being realistic in my expectations. I've attached a few pictures of the comparisons.

thanks for your advice
