When I prepared to install my new Dust collection system, 6” gates were a premium item. I looked around the internet for a good homemade solution and found many that used PVC pipe. I planed to install 6” 26 gauge snap lock pipe so I wanted something that fit correctly, that would seal up easy. So I decided to use parts from others peoples designs and finish with my own. Below is what ended up with.
I cut 22 – 3/4”x 8 1/4” x 8 1/4” pieces of plywood, I was making 11 gates. I was able to get this out of left over small cuts from my shop. I then centered the first piece up on my drill press and cut out a 6” hole with a circle cutter. I had to cut from both sides to get through the 3/4” plywood. So I set a stop box to keep all the holes the same.
After all of the holes were cut I glued left over Wilsonart laminate to each of the halves and routed out the holes.
I used 6” HVAC starter collars to transition from the plywood to the duct system. 2 halves are needed for each gate. You have to cut off the crimped section on the female half.
You also need to cut 1/4” off each of the tabs to keep them out of the gates slide.
Then insert the collar into the plywood half and nail or staple each tab down to the plywood.
This is a finished half.
Then cut 2 – 3/4” x 8 1/4” pieces of 1/8” hard board for each gate, cover each piece with thick tape on both sides. The tape will provide space for the slide to move. Nail these strip to one half of each gate.
Then cut a piece of 1/8” hard board that will fit between the strips from the last step but will completely cover the 6” hole in the gate. Make the piece 1” longer on each end of the gate so that the side will extend past the gate halves to provide self cleaning.
Take two of the gate halves, one with strips nailed on and one without strips. Be sure that there is one male half and one female half. The screw the two halves together.
Seal each side of the assembled gate with silicone.
Let your finished gates sit until the silicone dries. You can make and install any type handle you wish. I plan to just drill a finger hole in each slide.
The finished gates seal very well. They do open a 1/8” x 6 1/2” opening on the back side of the gate when open. But this only when the gate is open and does not affect the performance of the system.
