Thanks, my main aim was to keep as much rigidity as possible. Hence only removing material from one small area of the tool shank. As it still retains a full L shape it should keep most of it's strength.
The other consideration was to be able to drop in in and bed fully to all surfaces. Not only does this keep it spot on square it also locks up as one thereby not just relying on the dovetails for support/rigidity.
I can say it seems to have worked. Like Johns it cut's like butter at high speed. The tips also allow normal facing and turning as well. There are many different types of tips available for all sorts of jobs, inc threading.....I have to say this was a good investment, not that it cost much.
I'm chuffed with the outcome....

Glad to say all fixed and back together now......
