robv Sorry Mate i Just saw this.
I am lucky enough to have a friend with a mill.So it was put mating face down to ensure it was level. A saw bit in the drill press and cut around. it was amazingly easy and made welding it easy.

Ah, hadn’t thought of that!
Best that I had come up with was to roughly cut the bellhousing, and then put the thrust bearing snout into the jaws of the big lathe and bring the cut face back to square.
Spinning the whole box didn’t have much appeal!
