Hank, that's awesome! My shed is about 30 ft. from my neighbors bedroom window, who works alternating shifts. So I never know if he is sleeping when I'm in the shed. I'm wondering if I can build a carpet lined box to house my 3 gallon Rigid vac in my shed. Thanks! The wheels are rolling.When I lived in Japan where houses were 3 feet from each other, I had a 9 x 12 shop in my back yard. Half a meter from the wall was the baby's bedroom of the neighbor behind. I made an enclosure completely surrounding my DC system with carpet lining the inside and a baffle lined with carpet also. Very very low noise; I could speak on my cell phone 2 feet away from it. Didn't have to worry about my neighbor's baby waking up when I turned the DC on.
