good idea (781 views) 
Message: I think I'd need a counter balance weight for the door. With a conventional height ceiling, the door spring force gradually diminishes as the door goes up, at roughly the same rate and the weight of the door thats still on the verical part of the track.

If the door just goes straing up, the weight and tension on the chain will be constant. An egineering puzzle...hmmmm.
