Oil Derrick

I think this will be a perfect landmark/vibe/descriptor for a Texas/Oklahoma town.
An old-fashioned oil derrick.
Below are the machinations of my miniature/mind!
From Google image examples to example selection to sketches to shopping list to construction of a platform (the last photo).
Next, I'll go to our local craft shop and see what sizes/types of dowels, etc., are available, revising plans as needed.
