After realizing I had cut the top of my paperback organizer too short by neglecting to add width for the rabbet it was going to sit in I cut a new top from some free pine ply offcuts, figuring that very few people will see the top. I was also kind of irritated at myself and did not want / could afford to buy another sheet of birch plywood to correct my error. The free wood has a little bow to it that I was not able to put enough force on to unbow it during assembly.
I would now like to remove this and do things right - maybe I'll use up the rest of the Lowes gift card I received for winter holidays on the birch ply. Maybe I'll mill some solid maple I have in back. Maybe I'll do something else, but I don't like the bowed plywood - it is interfering with my thoughts to go forward with this project.
The plywood in question is screwed and glued in place. I think I used Titebond 1. After double checking that I have, in fact, removed all of the screws what is the best way to make the glue fail so I can remove this plywood piece and start over?
