I'm looking at the quick qhange tool posts for the Seig Super C3.
The one that arc auro trade recommend for the SC3 has only got a taper on one face. Does this mean that you have to ratate the whole tool post to do boring work? If so, is this not a pain in the backside?
Has anyone tried to adapt the series 100 quick change tool post from arc to fit the super C3. (It's part no 090-070-00405 on **LINK** 
. The heights seem roughly compatible. The C3 has an M10 centre post and the above tool post has M14 so if all that is needed is a custom post with M10 at one end and M14 at the other then this would be easy enough to make. Any thoughts?
Thanks
