turn/polish crank

How far can a stock crank be turned?
Here are the specs on it. Can this be turned/polished one more time?
Had .010" on the mains and .020 on the rods

they make bearings for .030 under - but most machine shops do not recommend using these. You have a higher chance of spinning a bearing if they get too thick, i think. YOu can polish the rod journals if they are not scored up. A lot of machine shops will give you a stock crank for not too much more dough than it would cost to clean it and grind it anyway. I know my local machine shop usually only charges $20 for a core on a stock 302 - they seem happy to get the labor charges for the grind job, plus they have a bunch of them laying around anyway.

Ok thanks I will have to check with them. I know they charge 75 to turn/polish them. Is this an average price?
