I had to make the radius turning tool out of odds and sods (so don't take the P*** ). The fabricated plate turns quite well, except it has hard spot where it's been heated by the weld, making chatter over small random areas (very odd).

The pics were taken about 0.1" from complete.
Bill, for the sake of the uninitiated (i.e. me, but a few others here i suspect) can you explain how the radius turning tool works and how you made it?
