Peter,
There are a couple of things you can do to remedy this problem, unfortunately not on the ones you have already pressed. First, you need to press your face veneer on a backer that is more balanced than the paperbacked one. That satinwood is a dense hard veneer and the paperbacked oak doesnt have equal pull to keep the two ply from warping excessively. I suggest another raw veneer, and make it somewhat similar in density to the satinwood.
Second, once you take it out of the press make sure to keep it waited under a sheet of plywood. No matter how matched the two veneers are a two ply layup will warp if left out.
The third thing is to press up the two ply and press it to your curved panel in the same day, especially if its going on a fairly tight radius. Unibond achieves a very rigid state in 12 to 24 hours making it harder to bend without problems. If you press up the two ply first thing in the morning and then press it your panel by the end of the day the two ply is well bonded to itself but still has some flexibility for your second pressing. I just sand it right before applying the two ply to the curved panel.
Sincerely
Darryl Keil
