How to temporarily seal off ductwork? - Aram - 09-04-2021
I'm plumbing in my Dust Gorilla in my new shop, using Oneida ductwork. i have a few pieces on order. I think I can get enough machines hooked up that I can use them, but that will leave at lest one 5" line wide open to the room. Aside from putting a blast gate on it, what would be a good way to temporarily seal it off so that I can run my DC?
Thanks.

I had to block off one of my ducts temporarily. I cut a piece of 1/4" plywood a little larger than the duct and duct taped it on the end of the pipe.

The plywood trick is probably as easy as anything, and it works well.

Love it. Thanks. Will do.

I have a 2-1/2” over my TS that’s waiting for a guard with DC port, and I just stuck a duct plug in it. Galvanized, with crimped male. The vacuum keeps it in place.

I used 3/4 ply to make a plug on a disk sander with a circle sanding attachment and the table set at a small angle. Then screwed a knob on where the center pivot point was located on the ply plug and Bob is my uncle. A removable plug. Been using it for many years.

Jeez, as a wood worker I should have used wood! My quick fix is a quart freezer bag and duct tape. Also used this on my blast gates that don't have a tool hooked up. With the DC running I can see every gate leaks by the bags sucking in.

<p>I have used a large 1 qt (I think) tapered plastic yogurt container, it slides in easily and securely into the unused 4" Y at the collector. Not sure it would seal/not get sucked into a 5" duct, but the principle remains...</p>

<p>Thanks, everyone. As it turned out, the one line I can't connect to a machine yet ends at a blast gate, so I'm good.</p><p><br></p><p><br></p>

<p>I have 5" ducting for my DC. I just got done reconfiguring the system, and to provide temporary closed ends so I could use the system while the reconfig was in progress, I used a tee cap that I keep around for the purpose. Got it a couple years back at the big box store; cost was less than $5, IIRC.</p><p><br></p><p>[attachment=37879]<br></p>
