And whilst I'm logged on – my usual "on-line" supplier doesn't seem to offer MT1 blank arbors any more. I've looked at the other usual suspcts and they seem to have dropped them too. I guess I could use an MT1 drill arbor or if really neccessary make them myself but my "to-do" (e,g. unfinished projects) list is already depressingly long. Regards, IanT
