This is my attempt to perfectly counterbalance a garage door. I did this:
1. Added a fifth panel (in curved section) in order to help linearize the lifting force.
2. Added an elliptical pulley and dead weight to counteract the force variation of panels going thru the curved section of track.

Your elliptical pulley is quite interesting. Do you know of any real life garage doors that use that technique? I've owned a lot of garage doors in my life and most of the newer ones used a large dual coil torsion spring that counterbalances both left and right sides of the door. Older doors made before the 1960's typically used two long extension springs. One on each side of the door and attached to a crank arm.

The scene is interesting and very well made. My only suggestion would be to make it move faster, if possible. It's really very slow.
Q: Do you know of any real life garage doors that use that technique?
A: No.

Q: The scene is interesting and very well made.
A: Thanks.

Q: My only suggestion would be to make it move faster.
A: I posted a new scene that is faster. Rope slows this scene down too much.
Cool
