Here are some photos of some minor changes I made to Golden Gates Coaling Tower. The photos show the walkway added to allow access by my "people" to the counterweights that control the coaling chutes.
unpainted walkway and landing extension
mock-up of attachment locations
form created to build replicated GGD's railing spacing.
this is a block of plastic with the rail and posts carved in with a router bit in a drill press and an X-Y table that moves the plastic to be routed in increments of thousand of an inch; the posts are 0.90" high and spaced 0.50" apart.
I added a 1/4" scale ladder cage that opens at the extended landing and the walkway above.
