not a bad design, like an adjustable spanner wrench... i might go get some flat bar and try that. also zuk, what do you use for the pins? i thought about using rollers from an old bearing or something like that... i just dont want to end up shearing one and have a bunch of bloody knuckles!!

thanks for the drawing too. <img src="/forums/images/graemlins/cheers.gif" alt="" />
