After seeing many ideas in a previous post about protecting an ashphalt driveway while plowing with a grader blade, I gave one of the ideas a try with some scrap schedule 80 PVC I had at the shop and here's how it came out. I ripped a 1/4" slot the entire length of the pipe. My grader blade is about 3/8". I had to beat it on from one end to try to slide it the entire 8'. The whole length just wouldn't slip on from the front no matter what I tried. Anyway, after about 4' it locked up tight. Had to cut the pipe and beat on the remainder 4' from the other end. There's really no way to fasten it unless I want to drill and pin my blade but the PVC is so tight on there I don't think it will go anywhere. I gave it a few good kicks and dropped the blade on it 4 or 5 times. It's pretty solid but we'll see after the 1st. plowable snow. (if we ever get any this year) I'm curious to see if it rides up over the snow or if it will clean it pretty close to the surface.
