Thabks Rod,

Think I'm going to give this a go! Are you able to shoot me
that video. I understand the theory (I think) just want to see it in action and how to pivot around polar axis.

I've always been concerned my segments mathematically may not have been perfect. From my understanding this method would eliminate that doubt. One question is how do you get the initial shape of the sector before sanding it smooth on the jig?

Scroll down the page to see it.

The advantage is that you are sanding the sectors smooth as you rotate them around a virtual polar axis.

Rod.
