This is the small sawmill shown in the Duncan Mills track plan (top center). Why build a small sawmill when later I’ll have a big one? To provide an industry while Duncan Mills is functioning as a switching pike. Besides, Duncan Mills actually supported at lest four sawmills, one in town.
I am going to assume this was a small mill serving a woods products industry (moulding, sash, etc.) Incoming loads will be logs. Outgoing loads will be box cars.
The sawmill will model the structure without the water wheel of Mabry Mill, a real mill in Virginia. Here are some prototype photos. The first is a distance shot of the mill.
The second shows the flume.
This is a cutaway showing internal operations.
A HO kit was produced by Muir Models.
And internal sawmill equipment is available from Woodland Scenics.
I wood model without the fume and divert the fume to Patriot Paper in Point Reyes Station.
The wood products manufacturing facility would be a face frame structure – source to be determined.
