Over the past several years, there have been many times I have needed a set of calipers for various tasks. Specifically, I have needed to measure a .45 barrel in order to have a barrel bushing made. Presently, I need to measure the dimensions of a barrel so that I can purchase another with the same contour. I also needed one to measure a set of bearings on a piece of equipment. I have never used a caliper. In doing some research, it appears there are a few different "models" or designs. What would you recommend for me? I want to be able to measure ID and OD of varous things. thanks
