From: Archimedes Plutonium on 30 May 2010 02:37 A very strange thing happened to me both yesterday and today. I closed the garage door, of which I have double garage doors, and as I closed the door, I felt the door come crashing to the cement, and instantly realized that the coiled torsion spring inside had broken. So I went inside the house to get to the garage since the other door was all blocked off and inaccessible. And as I inspected the problem, sure enough the torsion spring had snapped. So, now I had a problem on my hands since the door was too heavy for me to lift for it had 5 sections of metal panels and would have to get a "farm jack" to begin to lift it or enlist some neighborly help. And so I had the remainder of the night to think of the best solution. And I came up with the idea that I would use the other garage door and move the stuff that was blocking it. The other door was smaller with only 4 panels. So early this morning I started to move the stuff. And opened the door and tested it out and it was not as smooth of motion as my primary door, and maybe it just needed some lubrication. But later on in today, I closed this door after fetching a lawnmower and funny, how this second door torsion spring also broke and the door came crashing down on the cement also. Another checkup from inside and sure enough the spring broke also. And both of them broke about the same exact distance in the springs. So is this a probability fluke? Or is this somewhat probable, that a manufacturer of torsion springs would have equal quality on the springs that they would last for the same years and break within 24 hours of one another? Could it be that they had the same weathering history that they would break almost on the very same day? Now I was not wanting to have such a problem come my way on this weekend, for I was not caught up on alot of work that needs my dire attention. And here I have my pickup inside a two car garage with no door working, so that if an emergency comes up, I cannot get in my vehicle and go anywhere. So I give myself an A+++ today in mechanical engineering of doing my scheduled work for the day, but also, spending a brief 2 hours to fix one of those doors that I can get in and out of. I hate torsion spring garage doors because they are dangerous and too many moving parts and the torsion settings are very much unreliable with that silly and darn "set screw". I have heard horror stories of people losing fingers on those torsion springs. What I do love is the most simple mechanics and in the case of garage doors, I prefer the pulley with a weight attachment. The only bad thing about this setup is that in case the weight falls and it could do some damage to the cement or whatever it falls on, especially if a person is underneath the weight. So what I do in that case is, I finish with some catchment system like a board plank that guides the weight into a sand box should it happen to fall some future date. But within two hours of my time, I had a setup of a steel 50 lb weight on both sides of the door to reduce the overall weight of the door to a minus 100 lbs. It is not easy for me to open and close, but manageable, and the A+++ is for the fact that I had a serious problem and with materials on hand I solved it within two hours. And tomorrow I can do the same thing with the other door for I have enough of the same materials on hand. The old torsion springs worked well for decades, but the day the set screw gets loose or that spring breaks is not as good of a system as the mere pulley and weights. So I will not replace a torsion spring with another torsion spring but rather elminate those springs and set up a pulley system. This incident also brings up a idea that has been brewing in my mind for some time. That a environment where I collect materials and buy materials gets to a point of what I call "levels or hierarchies of on site materials". Levels of organization and we see this in broader life, such as the difference between a big city and a small town that we can expect the big city to carry and hold almost all materials when we need them, whereas the small town seldom has materials needed on hand. So that today I had chains and D ring couplers and I had steel weights, all ready to go on fixing the problem. I even had spare pulleys.
