My small basement workshop lacks adequate air circulation, but finding the floor space to set a pedestal or box fan in my confined shop just wasn’t in the cards. Instead of looking to the floor, I found the solution to my problem overhead. I devised a circular platform that allows me to mount a small but powerful fan. The platform is then mounted to a plywood base that has a section of T-track recessed in a groove. The base is long enough that I can position the fan to aim it at almost any location in my shop. To make the base, cut a groove down the center and install the T-track. The base can be any length to suit the space you have available. I used a simple router trammel to cut out the circular fan mount platform. The trammel also worked well for routing the two adjustment slots in the platform. The circular platform has a couple of adjustment slots that let me rotate the fan almost a full 180°. The platform is held to the T-track with a pair of threaded knobs, hex head bolts, and washers.
