Andre Martel Medium Caliper 10" to 20"

I turn large deep utility bowls, and regular calipers can't handle the depth I need for checking wall thickness. This is just what I needed for my large bowls. Also the thin points fit into the slots on my vic marc chucks so I can determine the bottom thickness easily.

Absolutely brilliant

I use a recess in the bottom of side grain bowls and platters. These calipers are thin enough to fit between the jaws of my chucks and give me an accurate measurement of just how thic the bottom of a bowl is. The shape also works well with deep bowls

Have small, medium size. Easy to use.
