/diy/ - Do It Yourself

>>2556688
It's a slatted taildrum roller for a large conveyor that carries rocks. The idea is that if a rock gets on the underside of the belt, instead of punching a hole through it, it'll get pushed between the slats, and bounce around inside until it is ejected out of the hole. The belt it is going on is probably worth 100 grand so it's worth the effort.
