Here's a dolly I threw together. Took a few different plans from a few different web sites and made my own. Runs along 1 1/4 pipe. Still in the process of figuring a way to make it possible to add longer sections without any sort of bumping. The wheels I have on there now are off of my old flowboard and are temporary. If your going to do it right i suggest ordering some of these
But they look a little small so i might go with some Gel longboard wheels if they dont cost to much.
Full material list will be up in the next few days.
