Well i finally got round to building one. I had been meaning to for a while but always put it off.. after reading the DIY thread and icassell's (i think) enthusiasm towards his recent build i decided to build one. I wanted mine to work with the flash on the camera shoe and be light weight, and fairly big. It all fell into place. I used an old CD spindal for the inside hole and there was a plastic mixing bowl in the kitchen which was perfect for the job (so i scavanged that).. just waiting for the paint to dry now but it seems to be working ok. quick snap, i'm too ill for anything better at the moment. I'll get pics of it up tomorrow once it's all done. glad i built one though, pretty nice.
