I am replacing the bottom on a piano bench. It's made out of cherry. The Staples are held very strongly in fact some of them have snapped off when I've tried to remove them. Along the length of the piano bench I have had no problem because I have access. However, the placement of the Staples on the end pieces makes it nearly impossible to use anything to remove the Staples. I've included a picture of the problem. Any suggestions on how to best remove the Staples without damage?
