Live Steam 1/4-Scale Model Logging Donkey
1/4 Scale Model Steam Donkey. Weighing around 250 lbs. and measuring 57" high x 24" wide x 46" long. Bronze castings include two engines and cross slides. Also included are two 6-inch diameter by 3/4-inch steel crank disks, bronze eccentric, cast iron piston and rings, and all moving parts for the engines. The two engines run on 25 lbs. of steam or air pressure. The bore is 1.75 inches with a 2-inch stroke. It also features a 10" x 24" boiler that is 3/8-inch thick with a Penberthy injector, oilers for both engines, a pop off valve set at 100 lbs. and two 9-inch spool drums with oak clutches, braking system and ratchet-and-paw.
You can see the Steam Donkey running on youtube. Below is the link:

The boiler has a waterleg. There is a 3/4 inch space between inside the boiler shell and the outside of the firebox.
The tubes are made of 1"x .065" copper boiler tube and are 15" long.
The last photo shows the 1 inch copper boiler tubes being rolled in.
I will build a wood crate on a pallet and deliver it to a freight terminal in Seattle.
