Cheers mate!, and thanks for the offer, Im not gunna worry about it for now, Ill decide on a spot for the isolator when I fit up a couple of other things on me list, what crimper have you got, Im gunna have a sqiz on fleabay and buy a decent one, Me mates a fitter and used to work open cut many moons ago, Ive seen him do all his old style years ago (with a cold chisel) but know he bought one a while ago so ill suss him out when hes not busy.
