The system began a few years ago when I needed more light stands and, like most DIY types, didn’t want to pay a lot for them. I happened to have a lot of 3/4″ PVC and 1/2″ metal conduit laying around so I started experimenting. My goal was to come as close as I could to the functions of a retail light stand. The basic stand fits the bill except for the fact that the legs don’t collapse. Since this was a DIY project I wasn’t limited to manufacturer’s accessories. I could dream up as many different add-ons as I wanted. The simple stand soon grew into a complete light support system.
