I've never had it done but I've certainly seen pictures of cranks that people welded then offset ground in order to make a "stroker" crank.
I'd assume the crank would have to be steel in order for it to be welded and reground (is that compressor crank steel?).
My other thought is, can the crank turning machines used for regular automotive rebuilding be adjusted to accept such a small/short (i'm assuming here) crank?
In short, I have no idea and have been no help
Best of luck

I Think for a spun bearing or to bring a crank back into tolerance ,std/std they chrome the journals and grind back to spec
unfortunetly chroming is now expensive !!!
had it done years ago, flashed chromed, and brought back down to spec and it worked. it was a hemi 426 so lots of torque. and with that being said, i was at the machine shop recently and that topic came up for a certain crank??? and it boiled down to whether it was a steel or cast crank. i thought the prices they were talking, again ??, seemed reasonable compared to a new one.
how much could a 2 lung compressor crank cost anyway compared to the cost of the chroming and machining costs, it's already apart. unless it is something odd ball or it has some sort of a sentimental value to you, you have about 2 choices, fix it or replace it and either one of those usually boils down to how much.
