Agreed. The plan is to support the idler axle on both sides of the sprocket, extend axle on one side, then fix coder to that side.

Eric - thanks, but that photo's a little grainy in that area, I can't quite make out what's behind the sprocket (or is it hidden by the sprocket anyway?). Also, I planned on using surgical tubing or equivalent to give a bit of compliance. We've had problems other years with mounting plates that didn't quite line up the encoder axle with the axle it was encoding.

Thanks very much.
