no previous part Part 1 of Dust Collection series Part 2: Blast Gate rough draft »

after completing my Thien Baffle (well, a couple more things to do to it but has to wait til ducting is 100%).. next tackle is the HVAC 6” runs and duct supports. I’m directly running from the Thien Baffle inlet horizontally across my 2 car garage and branching off 8 6” wye’s and 2 4” wye’s along the 2”x12” board attached to the wall (which is hiding my horizontal electrical runs).
Today, I spent time fabricating the 6” supports with the help of my newly arrived Grizzly circle cutter (upto 8” diameter). I’ll have to give a review about this product soon as it helped me dial in the exact diameter I was looking for.
I made 12 supports.

That looks pretty good. You might want to round over those exposed corners, just break the sharpness off of them so you don’t do damage if you accidentally walk into one…

That’s going to be a solid installation, great work on the supports.

the added benefit for this: my entire 6” main will be running chest high horizontally from Thien Baffle to the wye’s, and this will allow me to attach a 8” or 12” running board shelf on top of these hvac support / shelf support brackets. I love dual purpose in a small shop :)
