Developed by world renowned woodturner Andre Martel, these calipers allow measurement of deep and odd shaped vesels.

Well made product, works just fine in a medium deep bowl. Wish it had a knob in the center instead of a bolt, so the tension could be varied.

I had a class with Irish Turner Glenn Lucas. He let us use his caliper. Great for checking bowl size.
