I’ve been using this style blast gate for 4” PVC dust collection pipe for a couple years now and it works great. They are easy and very inexpensive to make. I just made another pair and recorded the process. To make a pair of blast gates you need:
one 4” PVC coupling
a piece of pipe at least as long as the coupling
six 6”x6” plywood squares. Any thickness will do.
a scrap block for the handles
and some construction adhesive.
Here’s a short video covering the build process:
Also, I made a SketchUp video covering the design process:
