Gouged Crankshaft

This actually happened to me about 15 years ago on a SBC 350 build. I cleaned up around the damage mark with 2000 sandpaper until there were no high spot on the edge of damage. Yea, 2000 grit sandpaper, it's what I had handy at the time. It took like an hour. I then finished assembly. The engine is still running today and has almost 200.000 miles. So, it really didn't hurt anything.

I remember articles in OLD hot rod magazines where they actually taught you how to DO something, and you'd routinely see articles on using sandpaper wrapped around the journal with cotton twine wrapped around it a couple times, you 'saw' back and forth with the ends of the twine, spinning the paper. do not use a tattered, torn edge piece of paper. I imagine finishing with emory cloth or 3,000 grit would be pretty good for a street banger

get a honing stone and run it across the gouged area to make certain no high spots, then take some 400 crocus cloth as wide as the journal area and use a long shoe lace to spine the cloth and help polish it a little, there will be no need to run a oversized bearing or change balance, there wont be enough taken off of it to do any harm.

I've just started receiving Rod & Custom, and I'm glad they have a couple articles on actual DIY techniques. The rest of the magazines I've read have nothing but flashy photos.

I ultimately decided to go with an entire rotating assembly due to the fact I called four places around town and no one had a engine balancing machine. Not my ideal situation, but it solves my needing to find a machine shop with the necessary tools.

I would still send out pre balanced parts. I dont trust them to be that accurate.
