<VV> turn my crank

[corvair at mts.net]

One thing I can suggest:

* get shop to look at crank and estimate how much they will need to turn it - likely they will say .010 undersize.
* get a set of .010 (or the appropriate undersize) bearings and install them in your block.
* measure the diameters inside your bearings as installed.
* get the shop to grind the crank the appropriate size to get the bearing clearance you want - maybe it'll be .009 undersize or something like that.

Reason being - both me and a friend are in the situation where we have .010 bearings and .010 U/S cranks, yet we have excessive bearing clearance when the crank is installed, because the holes in the block are very slightly oversized.

And I would sure like to hear how people have resolved this - and I need to hear it like "I've done this six times, and it's worked" as opposed to "I hear you can do this - and it works" or "I hear that doing **** doesn't work"....

thanks people

The machine shop called today and said my crankshaft
was need of turning. The problems he had found
corresponded to the problems that I saw when I tore
down the engine. The bearings in first journal were
discolored and #2 piston rod didn't want to separate
from the crank. So I think the guy was telling the
truth.  My question is, and I will be showing my
ignorance here, what is done when a crankshaft is
turned? And what are the consequences of doing this?
I.e. will over-sized bearings be needed?
