I have a Rigid 12 GL shop Vac that I use for general cleaning up chips & also as a DC when I'm sanding. I have tried to put woman's pantyhose around the filter to try to keep it clean but the dust gets inside & clogs up the filter. I remember either seeing (you tube) or reading something where someone did something to a Rigid shop vac adding something so when they picked up the dust from the floor the shop vac was completely clean all the dust was in another container.
Does this sound familiar to anyone? if so can you please give me a link to this.
