Movers didn't secure the drop front on my desk, and it dropped and hit the front flat board. The drop front has a bow to it so it will lie flat. No side supports or limiters. The drop front rotates on the smooth upper part of a large wood screw. The drop front is 3 boards glued together. The impact broke the joint of one board at the edge where it hit the front flat board edge, but then the board itself split and the split goes out into the board, not along the join, all the way to the other end. The desk was made by Faribault Furniture Company in Faribault MN and I think is about 100-110 years old. It has been refinished. I'm looking for ideas for how to repair the damage and have the repair be as strong as possible so the desk can be used, maybe with some kind of reinforcement as well as glue. I'm concerned that the impact may have damaged the other two joins and they will eventually come apart. Any suggestions or ideas?
