A few days ago my garage door broke. Specifically the big spring broke. Having helped a few times with replacing a similar spring, I understood the dangers of doing, but this guy made me laugh out loud with the title “How I replaced deadly garage door springs, and lived to tell the tale”. He has an excellent reference on what makes the door tick err… go up, and while it is dangerous if you’re not careful, it’s no worse than running a piece of wood through a table saw (and I should know!). Thanks to my brother’s help we replaced the spring it in less than an hour. I’m sure a select few out there have lost limbs from letting a wound spring go, but the garage door companies also use it as a marketing ploy to push their services.
