The disaster-is-nigh technique: As he inspects your door, the serviceman grimly calls your attention to "cracks" in your garage door. These appear very faintly in the middle of the door where the panels bow under their own weight when the door is up. This is normal, but the type of thing you wouldn't casually observe yourself. This surprising revelation disarms you, and you may find yourself strangely susceptible to the pitch for an entire new door.
Speed of a thrown winding bar:: The springs, being in balance with the door, effectively are able to launch a typical 150 lb door at 10.6 mph speed. An 18-inch long by 1/2-inch diameter steel winding bar happens to weigh about 1 pound. Since momentum is conserved, this 150:1 ratio in weight of the door to the winding bar means the fully-wound springs could potentially throw a winding bar at 10.6 mph * 150 = 1590 mph = 2332 ft/sec, assuming the energy were perfectly coupled and transferred. If the energy transfer were only 1/3 efficient, this would still be the 800 ft/sec speed of a typical pistol bullet. Except it is a foot-and-a-half metal spear, not a bullet.
Install the stiffening strut on top of the top section of steel doors with the section lying flat. Then install the opener bracket that replaces the center bracket between the top two sections. While you’re working on the sections, protect them from scratches by putting carpet scraps on top of your sawhorses. Now, slide the rollers into the roller brackets.
