Will try that, although the only chisels i think i have are for an air hammer. I guess i will use those. I am following what your saying, im my Young weak mind i dont see how that will streach the soft collar? Streach the outside of it but the inner diameter i dont see it? Not saying this does not work, cause you clearly have done more of this that me.
On the other had i can see how scoring it and then chiseling it will streach it. I have cut half way through plety of things and streached them to remove them or split the bolt or nut or whatever.
Wow, cant beleive we have gone 5 pages on this so far!! Clearly you can see i like to talk!! Anyone finding this thread should have no question where to start!
