Steam Donkey that I built in 2015 whistle gauge off grid Ross Bendixen
This is the third Steam Donkey that I have built. Measuring 12' long x 42" wide x 82" high to the top of the stack. Cast iron castings include two engines and cross slides. Also included are two 6-inch diameter by 1-inch steel crank disks, bronze eccentrics, cast iron piston and rings, and all moving parts for the engines. The two engines run on 25 lbs. of steam pressure. The bore is 2.75 inches with a 4-inch stroke. It also features a 20" dia. x 42"tall boiler that is 3/8-inch thick. There are 22 - 1-1/2 copper tubes rolled in. A Swift oiler for both engines, a pop off valve set at 100 lbs. and two 10-inch spool drums that hold 500 feet of 3/16 steel cable. Oak clutches, braking system and ratchet-and-pawl on each spool.
