Looking for Cricket gauge tool

Ditto to Eric I used a 1/2"X3" carriage bolt. hooked it up in a hand held drill stood to the left of bench grinder with drill in forward. A flat washer, lock washer, and nut is also needed. got just about there then used emery cloth sized and polished it, cloth in hand drill in other. If you want to go crazy a felt disc and some mothers paste will shine it up
