This could actually be very cost-effective. If you want to make your own
door, rather than buying one. If the door goes straight up, it doesn't have
to be a sectional door. You can build any size solid door, or maybe a frame
with light weight covering (1/4" ply) to create a hollow core door. Some
U-channel for the rails, and proper counterweights and pulleys to "fly" the
door.
Kinda like the "flats" we use in the theater. But you probably want more
than a canvas door.
