So, I was scrounging around a friends garage the other day and I came across an old-ish set of rollers for use with a table saw. Its like two side pieces which hold 5 metal rollers on bearings in a row so you can slide pieces of wood on em. My question is, do you think they could be re-organized or used to create a set of rollers to ride on on the cheap? I dont really know the mechanics of rollers, so I have no idea, but I'm pretty sure I could get a similar set, or those for dirt cheap. Any ideas or comments?
