I have made four of these with two coming out perfect and two twisted. All four were square to within 1/32" when measuring the diagonals.

I squared the stock. I glued it together with biscuits and used Jorgensen cabinet clamps. I used two clamps across the width at each end. The frame sat on the steel bars of the clamps. I was sure that the long boards touch the clamps at all four points of contact. The surface was level under the clamps.
What am I missing?

Why are my frames twisted?
