Made with 3/4" PVC pipe, put together with screws, and Creepy Hands. I didn't say on the video but I found the best crankshaft "width" is about a 5.5" radius (the length of visible pipe between the center and outer elbows is 2.5") because the sleeves on Creepy Hands are about 12 inches long. I fiddled with it a lot to get the movement right, so it was good that it was screwed together and not glued.
