John-I am sure that somebody knows "the secret" about ultra-small chain & sprockets. What might be a limiting factor is that (as you know), chain for sprockets is much different than regular old chain and the tiny, TEENY links might be too small to actually make! With this said, somebody prove me wrong! The Grandt Line stuff may be the smallest "real" chain drive stuff available...but who knows? The search continues...or as agent Muldar said-"the truth is out there"...Woodie

Though I am still looking for smaller than 1/8 inch chain & sprockets I did come across a site that is quite interesting, they carry a numerous amount of parts from chain & sprockets to couplings,worm & beveled gears to name a few.
Modeling in large scale, a lot of what they have will be useful towards future projects, some things are a bit pricey but what isn't anymore these days.
