Garage torsion spring question
 
I have installed a couple of garage doors that I did not follow the directions with and although they function properly I am consumed with curiosity as to why the industry standard is to wind the springs with bars while the door all the way down. The way I did it was very easy and seems much safer. I figure there must be a very good reason it is not normally done this way but can't figure out what it is.

I position the door up so that the bottom cable attachment point is as close to the cable drum as possible. The cable is then wound onto the free wheeling drum and attached to the door. At this point I put about 3/4 to 1 1/2 turns on the the bar and tighten the set screws on the cable drum. There is just enough tension there to keep the cable taught at its shortest position. Both times I have done this the doors have functioned properly afterward. What am I missing?

You are missing the danger of the unbalanced door falling on your head?

How big are these doors, and are they insulated?

The door is very much in the way when winding the spring with it up. At least it is on the doors I have seen where the spring is wound from the center of the door. The door is also normally installed in the down postion and without the sping it is almost impossible to lift.

They were non insulated 7X16. Easy enough to raise and lower without the springs. The winding cones were never used to wind the springs. they get wound as the door goes down.

some are wound at the ends,with the door down its eaiser to know when your close to having it wound enough .instead of constantly lowering and raising it
