Scratchbuilding a portable sawmill

Post by Mik » Mon Jan 18, 2010 8:21 pm

Many logging operations hauled all the rough logs to a big mill for processing. But sometimes, depending on local conditions, this wasn't the most efficient or cost effective option. Enter the portable mill. It was designed to be easily broken down for transport to the logs, instead of the other way around. These were most popular in the East. Pennsylvania, New York, West Virginia, Ohio, Kentucky, where smaller disconnected woodlots, and terrain made the huge cable logging operations like those found in Washington and Oregon impractical. However, Andrew assures me that there WERE several portable mills used on the west coast as well.

Enough blathering, you say? Get to the pictures already? :D

The model was built of wood and plastic in 1/2" scale (1:24) without formal plans using the above photos, and a reprint of a Frick Sawmill parts book purchase from Nation Builder Books. For those who absolutely need a blueprint, this is the best I can provide.http://i397.photobucket.com/albums/pp52 ... joined.gif

In the beginning was the Husk. Word to the wise. Don't try to use oak on a model. It's a pain to work with. It just happened to be onhand, and close to the right dimensions.

The mud and main sills (aka frame)... Yes, I switched to basswood

A "mankiller" top saw

And a special bonus feature; A Mack AC flatbed truck with log

Thanks for looking!

Very nice! I hear ya about using Oak. I used it for the same reason; I had it lying around. It does have some weight to it which was useful for my application and the hardness did not hurt for the machining I had to do.

Very nicely done. Congratulations! What scale did you build it in?
