Any machine shops that what Dan?
I know personally of an asshole that calls himself a machinist and an engine builder. He’s neither.
But like you, he has an unfounded fear of grinding a crank.
I was helping one of HIS machinists assemble some blown alcohol BBC for a boat.
He had THREE SETS of main bearings to try and get the clearance set.
It took forever to sort it out and it was still junk when we had it done.
I asked said asshole why he didn’t turn the crank .010 under and get the journals back to size and shape.
The asshole said “it’s a factory 427 crank, I want to keep it original”!
So I explained to him what an idiot he was (and still is) and told the guy I was helping to find another job as fast as he could. The moron signing your checks is headed for disaster.
Sadly, that fat drunk is still in business and still screwing people over even though he’s been bankrupt twice and he’s changed names at least three times.
And Dan, I didn’t ask what a shop you know of does.
I asked you specifically what your experience is.
You failed at that too Dan.
