Having read blast gate reviews, LJ projects, and researching the internet, I came up with my own design that appears to be uncommon if not unique. Rather than a push-pull gate, I developed a rotary design that seems to work well. One advantage is that it can’t jam like the push-pull type due to saw dust building up in the tracks.
The ones pictured are for 2” PVC. Dimensions are 8” wide by 4.5” tall case and 7” round discs. Stops on the discs position the opening in the gate exactly in line with the opening in the case. A finish nail serves as a simple pivot pin.
I used this concept to construct an air manifold for my dust separator shown with one connection on one end and two in the bottom.
