After it dried, I checked and all corners were out of square. After I looked at it, I checked that the plywood was not bowed.

Guess what three of the four sides were. When I used a spreader to push the sides flat, the corners popped into square.

I am going to try getting these flat.

While this was originally going to be without a faceframe. I will now add one.

Thank you again for all of your help.
good to see that you eventually sorted out the problem.
