I have a cheap Sears 3-gallon air compressor. It has worked fine for inflating tires.
I would like to rig up a tool for cleaning window screens by blowing the dust off them with compressed air. I am thinking in terms of a wand a few feet long with a fan-shaped nozzle on the end. (For reasons too complicated to go into, I don't want to just use the hose on the screens). Just wondering if (a) something like that is already available as a compressor attachment, or (b) would it be difficult to fabricate something like that with items from the big box store (air hose connector, PVC piping, etc.).
