This Veritas wall thickness calipers works a little differently than usual. With most thickness calipers, a probe runs over the wall on two sides and you can read the thickness. With this one you set the desired thickness and read on the outside of your workpiece how much you still have to remove … The advantage is less scratches on your workpiece. With a straight and a curved leg, you can measure the thickness of the wall at most parts of your workpiece. Up to 42 cm! Useful in the production of bowls and hollow forms.
After purchasing these calipers, it is your own fault if you turn through the wall. 🙂
