Some years ago I treated myself to a new chuck from RDG. The HBM chucks seem to be a reasonable thing for the price although runout could be better. Anyway, yesterday I realised a set of soft jaws would be useful for a job I'm doing at the moment but RDG don't seem to have any listed for the 125mm diameter chuck, although they do list hard jaws both external and internal for that size chuck. A quick Google search only throws up one other supplier of HBM jaws and they don't list any soft jaws for the 125mm chuck either.
I was wondering if anyone else has had this problem and overcome it somehow. Are the 100mm jaws the same slot size and scroll size perhaps. Ian
