Today I completed my two day project which was to build a tire rack for my garage above my garage door opening. I started out buying the 2x4's, set of three hinges, chain on Friday. On Saturday I started my actual build. I made the rack 22 inches deep by 6 feet long. I offset the middle support with a 10 inch spacing.
The reason to the hinges is so I can rotate the shelf out of the way if I need the extra room to get things in and out of my low ceiling garage.
I thought I had enough eye hooks and other material to complete the project Saturday night, but turned out I only had two eye hooks that were useful. Here is a picture of how the project ended Saturday night.
