I have been trying for some time to identify a simple low cost solution for postioning a dust hood and came up with this idea A used TV brackets purchased off Ebay The ones which swivel could be used for dust hoods and the one which move in only one plane to mount a mobile tool tray
They could be mounted to the wall or tool and take up no floor space which is a factor in many shops The the tool tray can be moved out of the way when not in use and could even be used as a spraying platform
