Don't worry Boys, I approached that task with some trepidation. The thing I was cutting was a piece of real easy to machine 4E cast iron. I do have a Vertex 6" RT but it sits a bit too high. The little Hercus table is my favourite.

Faced with a similar operation again, I'd use a wider, thicker flat bar tee bolted onto the rotary table and the workpiece secured by means of hold downs threaded into the flat bar.

I'll post a show and tell on those clamps.
