If I can find a source I'd make new gauges with another piece of 10 mm on the other end.... or not. By the way what is the standard equivalent of 10 mm exactly. Bet it's slightly less than .390 Dale Dale, What an elegantly simple idea. In using one of these; is there a reason to go with .370 dimension rather than the full .390...other than the fact that .370 can be had off the shelf, and you need a lathe to get to .39? Seems like .39 would skip the shim bit which always seems to turn out to be an exercise in inefficiency. On the other hand .370 allows the tool to be used in various gradations.....?
