as I have a decent, vintage, 2-3" micrometer now with a 2" trueing block I decided to try a set of these - 13.50 delivered or so from the cheapest china ebay seller, and came within a few days. Sprung rams on each side and a lock function at the base. I realise they aren't going to last forever, but they feel useful, low tech, and good to experiment with?
