Tom, Not what I was wanting to hear but after spending several hours scouting the internet I was afraid that this was the case. The plywood on my front doors is not the problem as they are separate pieces for the exterior and interior. On the rear doors however the door is only one panel thick and it appears to be mahogany plywood with a veneer of birch applied to the inside.
I live in the Oklahoma City area and will start looking for someone capable of properly laminating the necessary pieces. As to varnish, I purchased Epifanes and Interlux Schooner 96. I played around with both of them and settled on the Schooner, I'm pleased with my results to date. Your plywood panel looks great, I assume you used filler/stain on it to create a level surface? Thanks for the info. Mike Higbee
