old southern pine density?
(OP)
Anybody know what the DL psf of southern pine from the 1920s was, or the density? I have worn out the phone and google... I have to be as accurate as possible on the weight for a remodel.
3/4" diagonal pine sheathing on a house from the 1920s, in Western North Carolina.
cheers!

I actually just found the answer in an old 1899 "Building Trades Pocketbook". 4 psf/inch!

AGAIN, using my very, very trusty HP calculator, that translates to 3.44 and 2.63 psf respectively for 3/4" material. Might check and see if that 4 psf value/in. is a seasoned value or not. Could be a little high.
On considering the long range implications of these calculations, does this mean that old southerners are dense?

Long Leaf Yellow Pine: 44 Lb/Ft^3
Short Leaf Yellow Pine: 38 Lb/Ft^3
Both were, and are, considered to be "Southern Pine".
If you need printed documentation, you can download the book from this page of my website:

Both the 1917 and 1934 Editions of the Carnegie Pocket Companion also list the same values. So, that pretty well covers the 1920's.

But, is that calc for today's "skinny" cuts of wood, or for the "original" defintion of 2x4 and 3/4 thick boards or for the roguh cut old-old wood?

Better qualify that last statement. A lot of us here are independent contractors...

hokie66....I'm a lot more dense than Southern Pine. I'd be classified as hardwood....and not necessarily in a good way.

Just curious on how you would have to be that accurate where +/-1 PSF of DL on the floors or walls would make that much difference?
