My primary use of SketchUp is to help design and visualize a project before I even make the first bit of sawdust. However, in this case I really didn’t need SketchUp to make any preliminary designs. I’m basing this video off of a previous blast gate design that I have used for a couple years now. It’s a simple and effective design.
In this video I’ll show you how to make a blast gate for use with 4” PVC pipe. The blast gate itself will be made from 3/8” plywood and some scrap wood for a handle. The connections will be made from 4” PVC pipe and a 4” PVC coupling. The coupling side will only be half of a coupling though. More on that in the build video later. Until then, you can watch this video and see just how easy they are to make.
