Re: Sprockets as Chain Tensioners?

I've been interested in making a simple test bed for something like this but I have no idea what I should be measuring - I assume current draw?

Personally I'm going to wager a guess that friction in tensioners is essentially negligible. Shaker just uses blocks of Delrin or nylon pushing against the chain (not spinning) and we have no problems at all. We even had a multi-purpose Delrin rod we used as both a tensioner and as a structural member (standoff)
