In the past few years I've posted bits and pieces of a paper mill I've been scratch building using multimedia and photo montages laminated to Masonite structure shapes.  It was intended to be an HO scale representation of a Pacific Northwest mill where I worked during my college years.  After about six years of on-and-off, now-and-then work, the mill is completed - that's the good news!

Attached is a libreoffice calc sheet to calculate the actuators behavior depends on the geometry, the material properties , the diameter of the wire and servo rotation, for a common turnout switch.

Here a short clip of my paper mill layout, it’s a 10ft x 8ft U shaped switching layout. 

The paper mill comprises of three tracks and two turnouts, which the branch comprises of three track, two on the branch itself and one that leads to the paper mill. There is also a tiny MOW siding which normally houses the railroad’s crane.

I’ve cherry picked ideas for Dunn Papers at Port Huron, MI and International Papers in Biglerville, PA allowing me to have a number of different that’s of cargo arrive and depart from the mill

I rarely ever break out of my comfort zone of wood kits. As I was packing/moving my shop to the new studio I found a few boxed treasures sitting on my "other stuff" shelf.
