Small project - I wanted to get my air compressor off the floor. The hose was always getting in my way as well. I was going to mount it on the wall but I was worried about vibration, and I also wanted to maintain portability. The solution was to hang it off the bottom of my cabinet was eye bolts with springs to dampen the vibrations. I then added a HF hose reel. With it mounted this way, it's still completely portable yet still out of the way. When I get a larger compressor in the future, I have room to put it in the same spot.
If anyone is curious about the reel mounting, it is lag screwed into a 1" red oak board, which is then attached to a stud with 4" lag screws.
