It's been done many times. Do a search on Barber Chair, named for Mike "Tyboo" Barber who was, I believe the first to do it. There is a pictoral essay in someone's album on how to do it. If I wasn't waiting for the fat guy to come down the chimney and bring me all my goodies, I'd find it for you. If he brings me the same lumps of coal he did last year, I'll do it for you tomorrow.... :xlol
