Here goes nothing. I've been leery of posting unfinished projects but ........
Bulk carriers ply the Great Lakes carrying Iron Ore, Coal, Wheat and other bulk cargoes. They are now, for the most part, self unloading. Around 1900 a device was invented to unload these boats called a Hulett Ore Unloader. None are in use now, but there is hope to rebuild one from saved parts in Cleveland.
I first built an operating ( most functions) prototype to see if it worked.

It was based on the earliest steam powered ones.
I obtained a copy of the design.

I was able to enlarge it to about 1:40 Scale and have started on the build. The base is 6 x 2 Base-plates.

As I progress I will post updates. I am using Stud.io for drawing and building instructions and will put it all together ---I hopa hopa hopa!
