Hi Jim,

I have used the angle Iron approach for sagging keybeds or the old Kimballs
with the "washboard" keybeds. I used a skilsaw and cut a kerf 3/4's of the
way through the keybed then placed the angle iron in the kerf drilled holes
and screwed it to the underside of the keybed.
For your purposes I don't know why this approch wouldn't work with some
modification. Perhaps placing/gluing a hardwood strip in to the keybed for
the screws to hold onto?
Good luck,
Mike
