I have been searching for one of these , as I have recently purchased a Kearns HBM with the facing Chuck , but no tooling as the seller was still using the other one he had.
I have a reasonable collection of Cat30 and NMTB30 tooling which I wan be able to use on the borer as well as my milling machine.
As I have not been able to find any ready made adaptors , I am nearly finished making one .
I just need to make the drive dogs and a couple of drawbars .
The internal taper wasnt too difficult just slow and careful checking as it went.
Has anyone made a similar item and if so has it been a success?
