Um... The guys refurbishing Sherman's on that Discovery show might disagree with the Sherman tolerance issue. They were not happy when they tried to put two of them together to make one good one and bitched the entire show about tolerances and how the priority was get them out instead of use a measure. That being stated you missed my point and then backed it up. I was talking to quality vs quantity as a philosophy, which you seem to support. I was not going down the tolerances road for Shermans till you brought it up.
