As designed, the axle and the idler rollers require some simple lathe work. I'd like to do a little redesign so that axle can be made from stock materials without a lathe. The idler rollers are a little trickier - you could just use a bronze bushing, but you really need flanges on both sides. Our high school does have a lathe, but a crappy one, so I end up doing lathe work for the team at home - thus I'm totally motivated to make this lathe-free.
