He' gotta know how to use a mic.

I had a conversation with the machinist I use now when he was about to bush my block, and he measured a lifter for sizing. .9043 he says...and I said I had measured that one @.9042. He promptly told me that temp makes a difference while holding the lifter in a clenched fist, then opened his hand and measured the lifter @.9044. I thought back, and sure enough when I measured it, the garage was quite chilly in the morning. I was a little embarassed, but happy to know I'd found a competent machinist.
