Springs are joined to wooden frame by both metal and glue. Any suggestions on how to separate them? I'd ideally like to keep the frame intact for upcycling. Tried sawing into the frame to remove the part with the springs attached as you can see from the pic, but hit a thick metal screw inside the frame.
