DIY pool filter cleaner 

Inside of the pulley hole I believe is 3/8 the pulleys are hardened, and you cannot drill them out for a thicker rod kind of using that size

Yes I used sheet metal screws to screw into the pulleys

Three different ways you can attach the bottom pulley you can drill a hole in the rod and put a pin through it. You can also put a hose clamp or you can do what I did which was just use duct tape good old duct tape😂
