I rigged up some clamps to hold down the keyboard to a heavy bench, then I imbedded a quarter in a piece of hardwood and pressed the quarter into the slot of the plug on the side of the keyboard - and held that in place with another long clamp that held the hardwood against the side of the keyboard (well there was a sliver of space)[br]
Then I cranked away at the hardwood, turning it… I had to use a hammer.[br]

The net result, the quarter bent.[br]
