Basically, I'm still skeptical that you can run chain without ever planning to tension it. I have heard of it being done, I'm just not sure how.

5188 ran a chained drive with exact center-to-center distances this past year. We calculated the hole distance for an even amount of chain links, then added 0.018" to compensate for chain stretch. This number was suggested by Paul Copioli and confirmed by testing by 2363.
