Derrick attached to drive machinery

I have completed finally the derrick for the drive machinery.  It took me a long time because I had to scratch build the pulleys along with the wiring and it was complex.   

The derrick is on a wood platform made with individual boards and the derrick beams are wood.  The pulleys are card stock sides with a short piece of wood dowel between them.  The hook is a commercial metal casting.  The wires are pieces of brass wire painted black.   

The rear view above shows a ladder leaning on the shed, a wood pallet and scenery on a piece of card stock.
