missing from one of the jaws, and not the end ones !).
I think its a Toyo chuck on a Cowell backplate (14 x 1.5mm ?? - whatever,
its the older Cowell spindle type, not the newer one which I think is the
same as Unimat).
Anyone got suggestions of where to find a suitable chuck ? I think the 80mm
TOS ones from Chronos are too large when one allows for the jaws sticking
out, the centre height being about 44mm on the Cowell.
A Unimat chuck might do if I can remove the spindle area - anyone know a UK
source of Unimat bits, and know how the chuck is constructed ?
(I could either unbolt or machine away the mounting, I have access to big
machines if needed).
Ideally after something made with hardened jaws (prefer to avoid aluminium
jaws, etc), reasonably concentricity.
