After many years I finally built my 4" Polecat Jayhawk the I won at a past club raffle. I want to add a belly tube like the real Jayhawk has. What construction method have you Jayhawk modelers used to accomplish this task?
I've been thinking about 3D printing cable tunnels because that is so much easier than slicing tubes or dowels. They can be printed exactly to the section and shapes you need.
