Ok, I'm at work this morning, & in the lobby we have an old upright non-functional piano. Instead of wheels, or casters it's sitting on 4" thick solid rubber matting. Here's where I beat you I skinned it off down to bare wood with my Vic Cadet. I also used the wire snipper to sever a bunch of the wires in it (the piano strings), then I used the file to undo the small little screws inside the guts of it (I don't know what it's called) that holds the wires. Finally, I used the main blade again to whittle off 2" from the bottom of the feet to get it to fit through the rear door. Not bad for an old lady who is "just a receptionist". All -in all it only took me about an hour.
