This was not my idea originally. I took mine mostly from of Glass Impressions on YouTube, especially the ball bearing and spring tension part.
My shop the past year has been a headache to work in. Seemed I was always needing to vac the floor. Without a true dust collection system, I was finding out how much time I was truly losing just cleaning up. Plus there was always micro particles in the air. So two months ago I began to overhaul from pulling down everything on the wall and re-insulating to rearranging for more room to adding a new Grizzly dust collection system. There’s still a lot of work to do but I’m on my way.
The blast gates are primarily made of 1/2 plywood with 4” PVC couplings cut in half and epoxied to each side. I chose to use a 4” hose coupling from Rockler which fits tight inside the coupling. I used all thin wall sewer PVC for long runs until I reached the station. Some machines would take 4” and others needed to be adapted to 2-1/2”.
Picture #2 shows me placing the 1/4” spring and ball bearing inside the add on board where there is a hole drilled through one side. You see how Glass impressions made his at this link (https://m.youtube.com/watch?v=ACLFMAfV1fk) . I thought the screw would be used to adjust but I discovered if the right tension is found in the spring the screws need only hold it in place.
Making the blast gates was the most time consuming part. I’m not sure if it was worth it or not but was enjoyable.
