Sprinkler, you have all the answers. You obviously know nothing about measuring a shaft of any kind. Shafts are round. .030 deflection, one way equals .060 run out. Either way I'm past measurements and arguing with you about it. Maybe Abe should have said it looks straight, but don't know for sure. Instead he said it was straight. Doesn't matter if it is .002 or .030 out of spec. It's not straight.
