Hi Leo (The Other One)

That is exactly what I said Leo.

By cutting the exact spigot or recess, you have the complete surface
holding, but then you need more jaw sets for some flexibility, in the
sizes you can make them.
Also said that one way of holding does not fit all and every possible
situation.
However I do feel that the Oneway chuck and jaws do give me the most
flexible secure holding system.
As for the jaw marks on wet wood, there is little, and with some care
on dry wood, there is none.
Not only that but I very very seldom do not change the foot to a more
pleasing shape (my opinion OKGG) and turn the held surface away.

Have fun and take care
Leo Van Der Loo
