Torsion springs and tracks mounted
Well, that wasn't to bad - still a few evenings of work. Now to figure out the torsion springs. This is a real monster, 4 springs, two shafts that couple in the middle, brackets between each pair of springs, and end brackets with bearings for the shaft to rotate, plus the winding drum to roll up the cable attached to the bottom of the garage door. I had 8 1/2 inches between the top of the door and the beam, plenty of room to mount underneath - noting to line up the winding drum with the cable channel. So I get this act up and mounted and figure hey - not so bad - then I visualize the door coming up and guess what? It will smack right into the middle of the drum. I forgot to mention that the end brackets are supposed to mount where vertical and horizontal brackets all meet, but I didn't have room because of the beam above. So I mounted it a few inches lower.... now I knew why it had to go exactly where it was designed to mount.
Closeup of mounting bracket - see a problem here??
Great - so now what?? Can't mount under the beam, can't mount on the side of beam because the drums won't line up with the cable channel, don't want to take everything down to square one and remount walls to back edge of beam (later saw that this wasn't possible either!)
Next time - the solutions.
Great looking door.... but how do you open it???
