^ Can you point me in the right direction as where to find the Walz tube?
I would like to keep the original frame. Today, I polished all the internals and buffed the external part of the barrel where the pump slides on. It made a huge difference in pump resistance. I'm going to try to take it for a real test drive tomorrow and play a quick game.
I got most of the materials to build a gravity feed tube. I just need to get the rubber piece for the top.
