Here’s some blast gates I made. I cut up some of those black
plastic blast gates for the external fittings. The outside parts
are made out of 1/2” prefinished maple ply. The inside is 1/4”
markerboard, which I waxed. I’ve seen designs where the
builder used rubber gaskets but I wanted to keep it simple and
the rest of my ducting is far from airtight anyway.

The blast gates work really well and seal better than the
cheap plastic ones I made them from. Gates are accessible overhead
with a pull cord tied to each “ear”, I don’t have to walk around
my table saw to open the gate anymore. Also I can place
the gates closer to where the ducting makes a “Y” and thus
eliminate downstream leakage from having the gates at duct
drops at the ends of the ducting runs.

Nicely done.
I like the ease/convenience of operation. I’ll have to remember this one.
Thanks for sharing.

This looks like a great solution, and self cleaning too.

Elegant and clever. View Master Blast Gates. Nice work. I’m thinking of several places where these would be an improvement over what I have.

Kindly,

Lee

Very nice work Loren. Glad to get to see these as we might be building blast gates of our own soon. I am on the fence with building blast gates or maybe purchasing blast gates. Great job!

Oh, and thanks for the tip on using Her-saf bits on that Panel Router. I have not purchased any bits yet but it is looking as though I will keep that Panel Router and so I will be getting it set up to take over dado cutting. Looking at the Her-saf bits looks like the way to go.

Hope things keep going great for your DC duct work.

My cyclone isn’t all that powerful, so I’m obliged to try to keep
airflow only to one machine at a time… and also the filter clogs
quicker than I would expect. The reduction in suction sneaks
up on me since even when it’s pretty clogged it still gets
the nasty airborne dust pretty well.

How did you make the flanges to attach to the rest of the ductwork?

Like it. I might use those on my first DC system.
