Where I live there are no Woodcraft shops or similar. You guys are lucky to have them! Many times we have to invent our own devices. This is how I made my DC blast gates.
The wooden squares are ¾” plywood, hole size to suit pipe. I use 4” PVC piping from the building industry. The gates were made from some aluminum sheeting I had. I guess 1/8” plywood can also work. The one square is rebated to the same thickness as the gate. The two squares are screwed together with the gate in between.
I added a bolt to the gate to act as a stopper, thus preventing the gate from sliding out all the way. Screws and silicone attach the wooden squares to the pipe.
I am now toying with an idea for semi-automatic gates but I first have to try it out. In the meantime these ones are working just fine.
Hope someone finds this useful!
