Winding Up

Well, I came to my senses, realizing that leaving y’all with the impression that I was going to be doing something seen as dangerous (fixing garage door springs), then going dark-ish. Thanks for the kind thoughts, y’all!

First the good news – I’m fine, the garage door is working fine, and I had few issues with the DIY repair. Therein lies a tale.

I previously wrote, “I’ve ordered a pair that individually match the spec for balancing out my door. I’ll install both, and wind them with about half the turns that the single spring had, then adjust to the correct balance.” I’m sure that some of you spotted the error of my ways and were tittering up your sleeves, awaiting the denouement of this little vignette.

Here goes. Turns out winding two springs half as many turns works great to get a garage door about halfway up. That’s fine, as far as it goes (hur, hur, hur), but when you raise the garage door past that point, with the springs half wound, the cables on each side of the doors leap out of their guides and create weird metallic representations of a bird’s nest… AND the door is halfway up (or halfway down, depending on your viewpoint), and is unlikely to go to the fully up or fully down position without dismantling those bird’s nests. Hmmm. Once the bird’s nests have been detached and untangled, the door is halfway up (or down), with no counter-balancing spring to provide artificial assistance. Sigh.

So, I pulled the ladder over to centerline, rested the door on the ladder and untangled the messes. Then I supported the door, pulled the ladder back in, and muscled the door back down to fully closed. I re-strung and re-tensioned the cables, and started over.

I thought a little more carefully than I did when exhausted and pre-heat-stroke on 4 July. If I wind BOTH springs enough for the door to raise fully, the amount of spring force in the fully down position will be approximately double what’s needed to raise the door. I think that’s called Launch Mode. That’s going to be a different, but also bad problem. So, just use one spring…

This time, I wound one of the springs fully, which is necessary to ensure that the spring provides lift for the whole of the door’s travel, and a bit left over to keep tension on the cables in the fully up position. Yes, I did this carefully, with two winding bars, and my whole body carefully positioned to the side, away from both spring and winding bars. I coated both springs liberally with white lithium grease, which should decrease the chances of corrosion and early failure.

Net result: One functioning garage door, with a mounted, spare, non-tensioned spring awaiting the day the primary goes out. Then I can wind up the spare, and we’re back in business with very little delay!

Not much else exciting to report. We’re in the depths of summer: hot, humid, and hoping the A/C doesn’t fail. Of course, there are hotels for that sort of problem.

Fun things

I’ve been enjoying (on Twitter) @KatinOxford – she has an interesting perspective on many things, but she drew me in with her C. S. Lewis work, including How do you Solve a Problem like Susan Pevensie? – Wonderful stuff, and she posted that on my birthday this year, which means … something. There are regular twitter meetings on Narnia stuff, and it all makes me want to read the series again, with more adult and hopefully more thoughtful eyes. Kat has far more dimension than just that though, so I’ll simply recommend her to y’all, and keep going.

I’ll try to keep an eye out for more fun things to point out in the future. We need fun things – there’s a lot that’s pretty damn dire going on these days.

Winding Down

Our condolences to the family and friends of Sgt. Maj. James G. Sartor, 40, of Teague, Texas, who died on July 13, 2019, in Faryab Province, Afghanistan, as a result of injuries sustained from enemy small arms fire during combat operations.
