Agreed, in 2007 we didn't do it right, and chain was snapping all the time. I am trying to remember what exactly went wrong, but our tensioning system was terribly designed, if at all. I dont think we had a plan for tensioning at all untill we were mostly built. Alignment might have also been an issue. (IE, if the sprockets were not close enough to coplanar, the chain would pop off.)
