One of the goals of my recent shop remodel was to add a Dust Collection system. I chose the Grizzly 2HP system and put it in the uninsulated walkup attic above my shop. The floor of the attic was tongue and groove OSB sitting on 2X10 joists. The void in the joists was insulated with fiberglass batts, but I immediately noticed a humm resonating thru the OSB and joists. It wasn’t particularly loud, but I found it very annoying.
I improvised a frame that has worked very well. I had some leftover rigid packing foam that was 2” thick. I built a 2X6 frame that was a little over-sized for my DC base, plus a layer of foam around all 4 sides. I cut a piece of foam for the bottom as well. My DC is on wheels and to keep the wheels from tearing up the base foam, I cut a loose fitting OSB base that just floats on the foam.
No more resonance!! I can still hear the DC running, but it is very tolerable.
