i think ill give the wedges a go tomorrow, to be honest i just want them off and ill replace them with an upgrade maybe an ultegra hollowtech II (nice excuse

)
Might be better instead of using 2 wedges, use a wedge cut from one piece of wood with a slot in it that will just fit around the crank, then drill a hole sideways through the wood and put a bolt through it to help prevent the wood from splitting in half.
