Steam Donkey Logging

For many years, logging operations were limited to areas close to water where the logs could be floated to mills or to flat ground where animal power could be used. Horses and oxen dragged logs along roads paved with greased wood ties – skid roads. The process was slow and expensive and the animals could not negotiate steep terrain.

John Dolbeer of Eureka, California changed logging forever in 1883 when he patented the first steam driven spool donkey. These simple, rugged machines were seen for decades in the woods, long after the arrival of more powerful and expensive steam yarders and skidders. The early spool donkey provided no system to return the rigging to the woods for the next log, necessitating a horse or manpower to do the job. The need to reach out further from the machine and solve the haul back problem led to the development of the "Improved" spool donkey about 1900.

On Dolbeer's first model, he wrapped a 150-foot, 4½ inch manila rope several times around a gypsy head (horizontally mounted spool) and attached the other end to a log. The steam donkey pulled the log toward the engine. The engine was moved in the woods by attaching the line to a tree and pulling itself along on its log skids.

Operating an early Dolbeer donkey required the services of three men, a boy and a horse. One man, the "choker-setter", attached the line to a log; an engineer or "donkey puncher", tended the steam engine; and a "spool tender" guided the whirring line over the spool with a short stick. The boy, called a whistle punk, manned a communicating wire running from the choker setter's position out among the logs to a steam whistle on the donkey engine. When the choker setter had secured the line running from the spool, the whistle punk tugged his whistle wire as a signal to the engineer that the log was ready to be hauled in. As soon as one log was in, or "yarded," it was detached from the line; then the horse hauled the line back from the donkey engine to the waiting choker setter and the next log.

In addition to the men operating the steam donkey a man was needed to chop wood for the boiler fire and, if the donkey was beyond the length of a hose from a stream, then a donkey with water bags was required to lug water from a water source to the machine.

This model of a steam donkey  was scratch built by Colin Menzies in 1:23 scale from measurements taken by Tony Phillips from an original (see below, left/right) which sits outside the Roots of Motive Power in Willits (the land end of the Skunk Train and Colin’s home). The figure was acquired and painted by Tony Phillips (who lives at the sea end of the Skunk Train in Fort Bragg). The model won Colin and Tony an Honorable Mention at the National Narrow Gauge Model Railway Convention in 2004.

Locally there are two places to see steam donkeys. First, there are two restored steam donkeys in the Deli building opposite the Skunk Depot. They are on the opposite side of the building from the restaurant. Both belonged to the Union Lumber Company.

Second, about 20 miles from Fort Bragg on Highway 20 at Camp 20 there is a largish stem donkey that used to belong to the Caspar Lumber Company – see picture Above:

Associate Member Colin Menzies also made a model of this steam donkey. Photos of his 1:12 scale model (See the right) were published in Timber Times (see below) – a magazine devoted to logging and modeling logging activities.
