To do this, you need a pipe of different diameters. The diameter depends on the size of your gun. I did a total length of one and a half meters. The barrel consists of three parts. The base is cut with a grinder (I cut it with welding), it bends to make a cone. The middle part is straight, and at the end of the long the rim is made of a pipe. I made from twisted, but the usual one will do.
Next, cut out a circle for the smallest diameter, and in it a hole for the inner pipe. The ratio of the diameters is one to two. You can decorate the barrel with a rolled strip, but the usual one will do. On the sides, weld tubes for mounting to the frame. This is the main thing. If you have a well-developed fantasy, then you can come up with many more small details. Next, we make the frame. I took a metal profile. But this is not necessary, a corner is also suitable. Dimensions depend on the muzzle of the gun. Do not forget about the mount for him and for the wheels. The frame is exclusively studded with wood. If you are doing like me, from the profile, then you need a strip for sheathing. It's easier to take a corner. My wheels are made of iron.
And oak woods also look great. At the end of welding and locksmithing, we will be re-qualified as an artist. I painted the so-called cast iron. And the patterns are copper and gold. It turned out pretty well. In general, see photos, get inspired and create unusual things yourself from simple objects.
