Holy cripes! Yeah... he's an engineer... It takes longer to read that
diatribe than to teach a fourteen year old daughter how to rebuild the
whole door!
I solved the replacement parts issue in one fell swoop. I bought a DIY
door kit from Lowes. They carry all the parts, crossed by model and
size. Springs are cheap, and on the shelf. They have no problem selling
to the end-user.
In fact, the door I bought came with two stupid plastic-n-steel worm gear
affairs that cannot "let go" accidentally. I tossed them in the junk box
for a future project, and installed the springs normally with manual
winding rods. Otherwise, the springs are impossible to replace without
dismantling _way_ too much hardware. Without the worms, it's just two
parts and off.
By the way... don't engineers know about paint and its virtues?
