I just hooked a 10' length of 4" corrugated flex drain pipe to my Super Gorilla DC to see if it would work for temporary over the blade dust collection. Bad idea. This thing howls at a high pitched harmonic that is ear splitting. Anyone ever do this and come up with a cure or is the drain pipe simply NG? I was going to try a short length of rigid pipe on the end but I doubt its going to work.
I had the stuff and the DC is new so I am playing around (no pics so I must be a liar).
