[QUOTE="tony d willIiams, post: 1712553, member: 108777"] Reading the posts reminds me of way back when I was not retired. Some of the blueprints I turned in had no deviation written in as standard was ±0.003". Some I would write in the deviation, sometimes as tight as ±0.0005". Those I gave to the mold-makers not the machinists. If the standard is set and there are ten fitting faces the accumulation could add up to ±0.030" which is a very long way from precision fitting. Imagine a straight shaft with a 0.030" bend in it, say your barrel bore, would this be acceptable? I am not going to do the math but 500 yards would be an impossible shot. It all comes done to the purpose of the tool. Heavy wooded hunting with no shot further than fifty yards, extreme precision not needed. Hunting the plains or desert hills where the big horn hang out, precision would be a must. [/QUOTE]
