Title: Straight 1 1/4 " to female cat30 adaptor
Post by: Mike4 on January 16, 2016, 10:32:23 PM

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?

Michael

knocked up a 5C to int30 a year or two ago so i could turn int 30 tooling for the mill in my lathe. I've used it twice :-)

I've made 4 1/2 to 4 and 4 1/2 to 3 morse tapers for my colchester lathe spindle with great success.
