Would motorcycle tubes work or are they too thin? I have a few in 19" and 21" from my dirt bikes that I was hoping I could use. I guess I have a pile of 10" and 12" tubes from the mini bikes too for short conveyors. My thought with them is that they are very narrow and when cut and turned inside out they might retain some of their curved shape. Hopefully this would create a bit of a trough shape in between the rollers keeping the dirt on? Anyone tried it?
