Really interesting stuff particularly Terry's description of opening out the bearings so they are a sliding fit. I imagine that at the Austin the cranks and bearings would be measured with go/no-go gauges and classified so that larger bearings were used on larger cranks and vice versa. Some bearings and cranks must have been discarded. The modern day equivalent would be to purchase a number of bearings and then use the one which fits the crank best or, more practically, as Terry does, modify the bearing if it is too tight. It is great to see a consensus (if I am following the discussion correctly) that tight front mains are not a good thing.
Interesting use of non-standard front mains also Terry. What do you mean by "Next to the crank"? Do you differ from the crowd in your rear mains also? How about the middle bearings in 3-bearing engines?
And, not to go too far off topic, would Bob and Robert agree that gauges would be much more accurate than micrometers, especially in less experienced hands?
