crank grinding

Crank grinders are a dying breed! I live in Cincinnati and there are only two guys left here who grind cranks. And they aren't young puppies anymore.
The machinery needed to do this job is very expen$ive and it would take many many grinds to pay it off. Unfortunately people would rather throw stuff away then fix it anymore.
It is also somewhat of an art form to do this and not many young people are willing to learn trades like this. They may get dirty!
Ask a gearhead about a local "high performance" machine shop/engine builder they will know who to send you to.

I'm sure there's plenty of places closer to you than the midwest but here's the place I use.
I had my Atlas crank ground and balanced at Auto Machine Inc. They're located 40 miles West of Chicago.
It's about 5 minutes from my home so it's very handy for me. Good guys. Ask for Kim.

remember have them grind the radius on the sides, no square corners.

Any auto engine builder with the relevant reboring /crank regrinding machine will be able to do the job.
With respect to this answer, with the Norton crank you have to supply the crank with the inner flywheel removed ( just the two outer flywheels bolted together)-well it would prudent to clean out the inner flywheel :!: :idea:
 
I haven't needed a machinist in a long time (knock wood) but in 2004 a retired machinist (from boeing, I believe) named Robert Seymour (nicknamed the great seymour) did some machine work on friends bike that I was repairing. He worked out of his shop behind his home for "friends only"... since he was a retired person. 206 244 4563 I don't know if he's even doing any machine work anymore, but he's a skilled machinist. He's in tukwilla.

The main reason crank grinding (and rebuilding in general) is no longer common is that machines are engineered down to the -nth factor for lightness and performance. The highest performance engines, Formula 1 powerplants are pretty much junk after their short duty cycles are exceeded. There would be plenty of crank grinders in business if there was enough work to keep the lights on and pay the bills. Sadly, as in most cases, the problems are at the top of the food chain, not the bottom. Young people are reluctant to go into the trades because all the money is being beat out of real work. It's much more lucrative to shuffle paper and punch computer buttons than it is to cut metal and build things.
 
Raber's (look them up online) in California has done two jobs well for me, also can dynamically balance. Double box the crank and mail it to them
