This is a project that I started a couple of years ago. It was originally intended as a way to transport the ¼-scale 1857 Napoleon 12-pounder, but it proved more trouble than it was worth. Since I dismounted the barrel to get the cannon in the car, it was easier to simply carry the gun to the firing position and assemble it there.
I did use it at the gun range a couple of times. The aluminum rack is sized to carry either two 50-cal or three 30-cal ammo cans. But it was eventually put aside and forgotten.
Now that I have a truck to transport the cannon, I don't dismount it anymore. In firing trim it weighs just shy of 30 pounds (and is awkward to carry assembled). But the thing that finally made me drag this out of storage was the addition of the GB mortar to the arsonal.
With this I can haul the cannon, mortar, and my BP can.
The rack is constructed from aluminum flat bar, angle, and square tubing. The fasteners are stainless steel and there are are six SS eyebolts incorporated into the design for attaching bungees. The lower framework of the limber/wagon is poplar. The tongue is a nondescript 1⅛" hardwood dowel with a plastic shovel handle, and is removable.
A brass snap hook serves as a 'hitch' for the carriage trail.
If these wheels look familiar, they should. The cannon wore these 14" lawnmower wheels during its construction, until they were replaced with the Amish hickory wheels.
