I made the gadget this guy explains in his video. It’s a panel carrier or panel handle. (Below, you'll find I’ve uploaded a screen shot of the guy himself that shows him demonstrating how it’s used.) It's useful if you need to carry plywood, oriented strand board, drywall—you know, “sheet stock”. Have you used (or do you plan to use) any of that for subflooring, shop floor, sheathing, bright-reflective interior walls, etc?
He's titled it a genius invention, but it's not really his original invention or idea. He simply shows a good way to make one. Here’s his how-to video:
If you have metal-working skills, you can easily make one of these. Otherwise, maybe a friend or neighbor can make one for you... for instance, consider a trade of something
you make or grow for the panel carrier.
I'm also uploading a picture of mine. You'll see the one modification I made to what's shown in the guy's video. I used
round steel tubing, instead of square, for the grip itself, since I think that makes it more comfortable to use.
