Hello all,
     I've got a trivia question: what is bicycle chain?  Specifically, is
it ANSI 25 ,or 35 ,or is it something else?  Where can I find non-bike
sprockets that will fit bike chain?

Regards,
David Nugent

What type of bike chain are you using?

Modern derailleur chains are a pretty specialized animal, much
narrower than typical industrial chains, and have no bushings
in their rollers.  All modern bicycle chain is 1/2" pitch, but
derailleur chain is nominally 3/32" width, and often less than
that in practice.  

Non-derailleur chain, used on track bicycles, one speeds, and
internally-geared hubs (3 speeds, etc.) is 1/2"x1/8"

Just make them. The chain pitch is .500 and the roller dia, is .300. 
The Marks handbook gives equations for figuring out all the dimensions,
and they're a lot of fun to cut.
