Thanks very much!
Stonich's web site has interesting stuff, including this page:

which led me to this, very interesting:

Makeinu, you can send Stonich your cranks and he'll lop 'em down for you (but it costs more than a new set of bulletproofs)!

I'd guess any machine shop, perhaps even your lbs, should be able to do it as well.
