Closing in on our relocation to Lemon Grove. At this point nearly all my tools are down here. In order to make things easier for keeping the garage organized, I erected one more twelve foot long shelf that was disassembled up north and reassembled down here. While organizing things, I found myself moving our bicycles around the room quite often, so I decided that I would construct a shelf up above the ceiling joist in the attic area to put them out of the way, but then it occurred to me that lifting a bicycle up a ladder and putting it on a platform would be a difficult and potentially dangerous task. That's when a light bulb went off in my head. I had an idea of making something akin to an attic ladder. essentially a door that pivots down from the ceiling, so we could hook both bicycles to this hatch and push it up into the ceiling with some sort of spring assist to make it effortless. As usual, the idea evolved in relation to the practical limitations of the space and the available hardware I could find at Home Depot or Harbor Freight. I went to Harbor Freight looking for pulleys or a block and tackle as a means of lifting the hinged door with a mechanical assist. Although Harbor Freight had a block and tackle in their online ad, they didn't have one in stock. This turned out to be a good thing, because while searching for it, I found a hand cranked winch with a turn crank and a reduction gear that would eliminate the need for tying off a rope. I purchase this item for thirty two dollars without a fully formed idea of how I was going to use it in the final design, but confident that I was heading in the right direction. Next I went to Home Depot where I picked up two pulleys and an eye bolt.
I started this project at three in the afternoon. Though I wasn't certain of the final design, I was confident of where I wanted the cable to descend. I figured out pretty quickly that the attic door was not going to work, so I switched to a cable lift that was more akin to an elevator. The cable would attach to a piece of plywood at its center point and the bicycles would be placed on top of this platform and raised into the ceiling for storage. By five PM, I was able to lift the two bicycles into the ceiling, but I was having trouble establishing the center of gravity between the two dissimilar bicycle frames. It finally occurred to me after several trial runs that the single connection of the cable to the bottom of the plywood was inherently unstable and the solution was simple. I just needed a second anchor point for the cable higher up so it couldn't tip forwards or backward so easily. The next morning, confident of this solution, I constructed a center stand between the two bicycles that provided the upper anchor point for the cable as well as an attachment point for each bike to the platform itself. It still required some fine tuning to find their center of gravity, but it ended with a system that worked. Now the access to the bikes is easy, but they're not encumbering any space below and their storage position doesn't prevent the garage door from closing. Mission accomplished. Money spent was about $100.
