chuck insert or similar needed
HI all
If this is posted in the wrong place, happy for it to be deleted.
I have acquired a four jaw chuck, (not scrollchuck) which I intend to use for off centre turning.
However it has a 3/4"x10TPI female thread and I have a M30 vicmarc lathe
anyone know were I can get an adaptor, or adaptors
I have googled without much luck
thanks

Vermec makes a suitable spindle adapter for this.

Its a little bit hard to describe how, if it was mine I could pick it or drill a little bit and watch the swarf. Best if you dropped into your local machine shop and they should be able to give you an answer.
It is still OK to use, just keep the speed down.

Old Croc raises a very good safety issue about using metal machining 3 & 4 jaw chucks on wood lathes. Wood turners generally turn at far higher speeds than are typical in metal turning so chucks experience different loads & stresses particularly varying loads. Wood is not homogenous like most metals, & wood blanks start off in some pretty odd shapes so in wood turning there is more "impact" stresses as loads / cuts vary due to voids or irregular blanks.
I'm not sure why but in this past year I have seen more modified metal turning chucks from past years being rediscovered by relatives wanting to know their value etc. Must be a generational thing - pre 4 jaw scroll chuck wood turners must be going to the great lathe in the sky?Mobyturns
