I recently replaced a rolling desk chair that had several tears in the seat fabric. Since the wheeled pedestal of the chair was still in perfect working condition, I decided to repurpose it and create this mobile light stand for my halogen workshop light.
Dowel connector. After removing the tripod base from my workshop light, I matched a length of large diameter dowel to the wheeled base and the bottom of the light pole. If one hole is smaller than the other, wrap some sheets of paper around the dowel to act as shims. Now my worklight is easy to move around the workshop.
