Roger,

If the plane is held at the correct angle, and the pencil held flat to the plane, then it would matter little how close the ellipse follows the timber - so long as there was enough meat for the pencil to ride accurately. This assumes that there is a way to register the template to the proper location on the log without relying on the templates fit to the exact curve, as you'd need an awful lot of templates - unless you were working with very closely sized poles.

The trick I want to know is how the planes are held at their exact angle once their position is determined on the log.

But yes, it would be good to hear from someone that was at the demo.
