You need a master for something you have to measure, so you reach for a set of gage blocks and begin creating the dimension. But how are you going about it? Some machinists, with experience using gage blocks, will begin creating the desired dimension by starting with the largest block first and grabbing blocks as they go. Then they get stuck and start wringing their hands.
However, there’s more to combining gage blocks than just “stacking” blocks. When done properly, you can create any dimension from zero to four inches, to the nearest tenth of a thousandth, never using more than four blocks or never using more than one from each series of blocks. In addition, you are assured of minimizing wringing error and randomly spreading the usage among all the blocks, thus reducing wear on the blocks.
