« Part 7: Building overhead blast gates Part 8 of Dust Collection series Part 9: overhead blast gates installed and affixed new & improved blast gate to wall »

Today I worked on my 10 existing 6” blast gates. They originally had an opening the same diameter of S&W green PVC drain pipe which I affixed to the wood via construction glue. It did not pan out too well. I needed them to be 1/8” or little more of an opening to receive 6” HVAC duct. So had to disassemble all 10 gates and route the opening larger.
Helpful hint for anyone working on HVAC latch duct: sure, you can use the hand cutters and pay for it in blood droplets like the picture below (unless you actually know how to use these things!), or mark your lines around the pipe using a circular jig I made to hold both ends closed while middle jig moves every 4 ” for me to draw lines. Flatten out the duct and brace both sides of the line for the jig saw. Near perfection of a cut with no jagged edges or fatal pokey tabs thingies. I used these 4” pieces one each side of the blast gate. I have a hand crimper to make the female ends. I also used a air nailer to put in 8 nails to hold these pieces in.
