Using Rough-Sawn Lumber

January 25th, 2010 by KTU | 1 Comment | Filed in 3. Basic Structure, Notes on Approaches

Dimensional lumber used in framing (i.e., 2×4, 2×6, etc.) is usually sold after planing and kiln drying. That’s why a 2×4 is actually 1.5″ x 3.5″. The stick of lumber from which that 2×4 was made was originally sawn to dimensions of 2″ x 4″. The length of these “rough sawn” boards is the nominal length plus at least 2 inches. So an 8′ 2×4 in rough-sawn form is 2″ x 4″ x 98+”.

Ends of rough-sawn 2x8s. See how both the height and the length varies slightly. I mostly ignored these differences, doing a little sorting to eliminate any real big jumps.

Framing

The framing of the cabin was straightforward. We used rough-sawn lumber and 3/4 inch plywood sheathing. I used a simple framing scheme with no headers above the windows and a single top plate on the walls. I used 3/4 inch plywood power nailed to the lumber with ring-shank nails to tie everything together into a strong and stiff wall system. I was confident that with this heavy sheathing, the minimal structure would be plenty strong.

Here my father, my sons, and I are tilting up the first wall.
