also, I built this cart for the buzzbox out of an old bike and the framework from an old rusted out grain separator. I put the big wheels on it so it can roll outside up to the other barn in case the engine welder is down and andy (the ranch hand) needs it. rear caster is a HF 8" swivel caster.
I really like my rod box tray, it's about the best feature on it.
(anyone know if you can rotate pictures on the forum editor?)
