Review on Mitutoyo 050103 Center Finder Diameter by Ryan Garrison

I'm having trouble with pre-made options like durability as I just got them today and can't pinpoint durability. However, it looks like what you would expect from Mitutoyo. I bought to be able to center the wooden squares to make a chess board with holes to connect the individual squares together. I made a metal template to attach it to the bracket. This allows me to center the jig with the pattern set. Should work fine.
