In a previous post, I showed you a little bit about how to choose a material. I’ve found in my work at Big Blue Saw that many people have trouble deciding on a thickness as well.
If you don’t have a set of calipers or a micrometer with which to gauge the thickness of the material you would like to use, you can use common household objects instead. Use chart below to get a feel for various thicknesses. You could also use any of these objects to measure existing parts.
For thicker measurements, stack several parts together. For example, 3 CDs are 3 X 1.2 mm = 3.6 mm or 0.142 inches thick.
