In my experience, I always eyeball slop to be far greater than it measures. What I think to be 10 to 15 thous turns out to be 5 once it is gauged. On the other hand, if the eye is well practiced at such things, it can be uncannily accurate. Once, I was helping a friend, a machinist of some experience, dial in the steering head bearings on his bike. After setting the preload we had to measure for a shim. When, I started to go into the shop for a set of feeler gauges he said not to bother, we needed a .007" shim washer. Of course I couldn't leave it at that and I got the feelers. It was .007" right on the nuts. I asked him what was the trick to be able to judge a fit so well. He said it is really simple; just do it about 50,000 times and you'll get very good at it. George |
