Stiff Leg Derrick for assembly yard

I have finally finished the stiff leg derrick for the assembly yard.  There will be more details around the derrick in the assembly yard including figures working on the derrick.

The derrick is scratch built with a few commercial castings.  The hoisting machine is a Rio Grande Models kit.  There are two drums on the hoisting machine - the upper drum controls lifting the derrick boom and the lower drum controls the bull wheel which turns the boom.  The far support leg has wood steps to allow the operators to climb for adjusting or repairing the derrick cables and pulleys.  About half of the pulley mechanisms were made from card stock and the other half are metal castings.

The photo above shows the derrick in the fenced assembly yard.

The hoisting mechanism will be powered by a stationary steam boiler.

After adding more details and scenery I will decide what my next industry will be - always challenging.
