Achievement Unlocked: Didn't Kill/Maim Myself While Screwing With The Garage Door Spring.
Had a guy lined up to do the spring tensioning, but he got sick and bailed. Looked all over town yesterday for a set of tensioning bars. Ended up going the Amazon route and a set was delivered around 5A this morning. Apparently, a metro area of about a million people isn't big enough for any non-specialty hardware stores / home improvement big boxes to stock a pair of 1/2" steel rods; it was all special order. Went and worked on the honey-do lists for my aunt and sister while the rods found their way here.
Did my homework, wore eye protection and some armored riding gloves. The job was anticlimactic because I had a healthy respect for the spring and made sure I understood the process before having at it.
Door works very nicely now; smooth and quiet. I'm calling that a W. Now back to scooter stuff!
