cut a piece of piping to the length you want your hopper plus one inch (to account for plug and fitting into feed neck adapter). this will be your hopper tube. clean off any burrs with the utility knife. use the utility knife to whittle the sapling piece down to size and shape, coat it with epoxy and fit it into one end of your hopper-tube (long piece of PVC storing the paintballs), epoxy over and around the edges, being careful to not get epoxy down side of pipe.
