More fun with garage doors.
Those springs are a b!tch. This same door that is now broken (hope for a visit on Friday to check it out and bill me obnoxious amounts of money), has had issues earlier. At the bottom corner on each side is a post with a wheel on the end. The wheel travels inside the metal track to guide it up and down. The post is set within a bracket at the bottom corner to move the door.
Several months back, one corner had the wheel come out of the track. Of course, you can't manhandle the wheel back in there, so I'm mechanically inclined to unscrew the 3 bolts holding the bracket, put the assembly back together loose with the wheel in the guide, then tighten the bracket back in place. All is good, amen. However, in unscrewing the bolts that hold the bracket, this jack ass gets 2 of 3 out and is struggling with the last bolt. The bolt becomes cockeyed as it nears exit from the door, which is puzzling, but not as much as why the last damn one would be so difficult while the other two I could unscrew with my hand. Crank-Crank-Crank with the wrench to get that damn thing out and >>BANG<< the bracket and bolt just disappeared. I found them half way across the garage. I then realize I never took off the spring, and that caused the tension in the bracket-bolt arrangement and the cockeyed behaviour. I very well could have killed myself if it had shot at my face, that bracket was launched with velocity. I count my blessings, undo the spring, reassemble, and things are good for the next few months.
About 5 weeks ago, that same wheel came out of the track again. And that same jack ass went about taking out the bolts to put things right. And, you see this coming, I forgot all about the spring and was wondering why that last bolt was being a cock eyed sonofab!tch again. I had brought my son over for a lesson in how to fix things, so he's standing next to me as I crank-crank-crank that bolt out and >>BANG<< it shoots off again. Doubly blessed as the bracket shot across the room and avoided us both, but the bolt shot up, bounced off the door and pegged my son on top of his head. He left, crying, and saying he doesn't want to help daddy fix anything anymore. I think that's a wise move on his part.
