I assembled a second blast gate this morning in the shop and got it installed. So far, everything is working much better than I had expected. I feel that I’m being more and more like Sheldon Cooper every day, Whistling in the workshop is NOT allowed. Good thing to because these gates are nice and quite. These gates have eliminated the whistling that was being caused be leaking plastic gates.
Here’s some assembly and installation pictures for the table saw blast gate.

Notice that I had to flip the gate over once I installed the blast gate under the saw. I saved a few inches!
All assembled and ready to suck.
One thing that I was surprised by was that even with the “loose” tolerances the gates still seal. The only conclusion that I can come with is that the gate is being “sucked up” against the upper body and creating a seal. So one thing to watch out for when building your own, if you so choose to, is to make certain that the body is flat and smooth.
Even with laying everything on the workbench while I waited for the glue to dry, there always seemed to be a little bit of the pipe sticking through the body on the inside. So I made sure that I sanded the inside so that it was flat and smooth. For the cans, I used a file, always filing toward the body of the gate, to get it down even with the inside of the body and then sanding.
These are very simple and quick to build.
