Wookcut and One-way both control the knives very securely, at the cost of
constraining the knife to a precisely circular path. Woodcut does it by
swinging the tool on a turntable, with a fixed axis. One-way does it by
introducing a curved toolrest, which supports the tool along a fixed arc.
This means that both systems produce spherical bowl blanks. McNaughton, on
the other hand, gives the turner more leeway in choosing the path of the
cut. The result is that the bowls can be varied in shape somewhat. The
price is a greater risk of catches, and more frayed nerves.

I watched a demonstration of the McNaughton system by our (then) club
president. He was able to drop out one bowl after another without the
slightest difficulty. In fact, he is so relaxed that he uses the system
without the big handle--claims it works better that way. He has convinced
even the skeptics in our group, including me.
