For anything under 0.050" (#22.5 wire), consider the first 0.025" mark on the barrel to be 0.020" instead. Makes it real easy to just add 20 to the thimble reading, and divide by 2 (or divide just the thimble reading and add 10). Then when, not if - when, you check your replacement wire against the original, ignore the barrel mark and just match the thimble number from the original measurement so you only have to do one calculation. Tricks for the lazy and simple minded, like me. Ron N
