Aceton will disolve epoxy over time. MEK is faster. Both will screw up your wood though. When I was faceting gemstones, I used epoxy to hold the stone to the dop ( the rod that goes in the faceting machine head) When its time to take the stone off the dop, you could put the dop in a jar of MEK and let it set for a few hour. THE epoxy would break down and loosen the grip on the stone. The trouble was that as the epoxy broke down, it started swelling. The swelling would try to push the stone away from the aluminum dop. The breakdown started on the exterior and had to work its way to the center. The swelling would sometimes cause enough hydrilic pressure that the stone would break before the epoxy finally released. Heat is the best way to break it down, but you will need to get the epoxy up to around 250 degrees or more. This was safer on most stones. It's kind of hard to use heat though when the epoxy is sandwitched between two pieces of wood. Even when it breaks down, it still has some "stick" left to it. I have used a covering iron to heat epoxy smeared on a wing once. I would iron a spot for a few minutes and the quickly pick at the epoxy with an xacto knife. I could usually lift a square inch or so at time with minimual damage to the wood. This wasn't sandwitched between wood, but just on the surface of the wood. A well placed razor saw is really the best approach.
