Clough42 posted this video the other day and I thought it would make a great reference video. I do not have any Mitutoyo Digital Calipers. I use Shars for the most part. I usually plan to .001 tolerance and by cross checking with "real" micrometers I usually end up with in .002 or closer of desired reading. That covers 99 percent of what I have to make. Anything closer I rough out with calipers and finish with micrometer and gauge blocks at current temperature. Press fits and cylinder bores. There are several videos by You Tubers that compare cheap vs expensive calipers. This one shows the actual knockoff differences on one name brand.
