I have had a height gauge for many years, originally bought for use at work. It is a dial type, metric and 2mm per turn of the dial. I find it easy to missread, especially as I get older, and have longed for something easier to use at the museum for some time. One of the poor quality Lidl 6" digital calipers is being modified to sit on a Mitutoyo scribing block, and will be useful on the machines when it is finished, I will post photo's them. Meanwhile, I looked at Dasqua height gauges, 6", 8" and 12". The 6" is good for small work, but I liked the look of the 8" one with the removable carbide tipped scribing tip. It came today by DHL after ordering it on Thursday evening, and I am very pleased with it. A nice strong plastic case, two 2032 cells and it can reach 8 1/2" high.
