100% my house in BR was built in 1924. When renovating the original boards were so hard to cut and were all exactly 2x4. While new ones are not.

Yes, but the one on the bottom stood for a lot longer prior to harvest. Once that 100+ year old timber was harvested, there wasn't much left.

You could still get it, but lumber's much cheaper when you can cut saw timber at 25/30 yrs instead of 50/60.

Also not clear where on the tree the top board was cut. The exterior rings tend to be wider and the interior more compact, so if the lower comes from the center, it would have a tighter grain.

Imagine the first folks from Europe in America. Built a wood house, then burned it to the ground when they moved to retrieve the nails.

I was told you can't build stuff from fir anymore because "it doesnt meet code"

The old guys i knew loved fir because it held nails so tightly.

Its real. But the notion that a home is better because of being built with old growth vs modern lumber is a massive oversimplification.

The first picture is a guitar with an Old Growth Sitka Spruce top sourced from logs recovered from a river in Alaska.




The next picture is from modern harvested Sitka Spruce




This is one of the reasons Pre War Martins are so sought after and ridiculously expensive

Your right. The 1918 one would be true 2”x4”. Both in that photo are 1 3/4” x 3 3/4

Yep. My house was built in the 70s and it looks like that.

I tore out a work bench that must’ve been made from scraps. That wood was HEAVY compared to what you can buy today.

More demand for housing in turn requires quicker turnaround for lumber so your growth rings are smaller.

The top is pine grown and cut in the south where the bottom is more northern or western grown and cut. Shorter sap season means tighter rings and cooler climate. thicker rings mean the tree had a longer, warm season.

The real question is how much old growth like the older lumber, actually adds to the strength/rigidity of a home. Without that objective fact all the discussion is just feels. Engineered building materials are almost certainly better at managing actual loads than old ways of building even with slower-growth, higher-density wood.


Boyhood friend's grandparents dismantled their store built early 20th Century. The nails had to be hacksawed due unable to pull with a crowbar. The wood was used for the home they retired to.

The big problem with old wood is high resin content and flammability of it

The high resin content also contained natural chemicals to kill bugs and why some banned pesticides were made from ground up pine tree stumps then chemicals extracted.

You were given semi bad info. SPF, not the guy with a million posts, is incredibly common for interior, non load bearing framing.

I finished a cabin out with old reclaimed wood from a home built in the early 1820’s.

I pulled some 2x’s from the studs from the walls and began cutting them down to size. 200 years later that pine lighter knot scent was extremely strong.
Probably Long Leaf pine. Felt like it was almost fossilized it was so hard.

SPF has load-bearing and span ratings for a great amount of construction. Especially residential.

My whole house?

2 x 4 and 4 x 4 actual (termite proof by naw as long as kept dry)

vs

2 x 4 and 4 x 4 nominal today is more termite magnet
