That photo addressed the other beneficial characteristic of old growth wood, which is closer spaced rings and the resulting denser wood.

That's a direct contradiction of what you said above.

It was not intended to compare the diameter of the growth rings, which seem very similar anyway.

The photo was very much intended to illustrate the difference in the thickness of the growth rings. A growth ring is the change in the diameter of a tree trunk over the course of a year. The old growth trees grew at a slower rate, for a number of reasons. So, for a given trunk diameter, old growth trees will have many more, thinner growth rings.

You are confusing measurements. Two logs of the exact same diameter, one of them old growth, can have growth rings of very different thickness. Hence, log diameter has nothing to do with ring thickness or wood density.

Are you two going to be in

I wasn't planning on it, but if you are recommending it....

One fact that not everyone is aware of is that it is not just a matter of size when wood is involved. Two pieces of lumber with identical dimensions can have vastly different properties. Much of our structural and furniture components built long ago came from much larger trees than anything available for harvest today, often referred to as "old growth". Wood with smaller diameter growth rings will react differently with changes in humidity during and after seasoning, often resulting in warping, cupping and splitting that would not occur with a piece that had equal dimensions but much larger diameter growth rings. The rings within wood from old growth sources can look almost flat when viewed from the cross section. Wood shrinks and swells differently across different planes of its structure, with more changes occurring along rings than across them. That is why pieces with less curve to the rings are more stable and why panels and tops on old furniture are often one piece while those used for modern construction need to be edge-joined up from several smaller pieces to avoid stability problems. When it comes to beams such as may be required for the cathedral reconstruction, laminated timbers might be used to replace former solid wood ones.

We will keep trying until you "get it" concerning the importance of tree ring diameter and how it relates to rebuilding Notre Dame's roof..

Nah, I'm done. We are now measuring a different type of density. Sad thing he was right (well, he cut and pasted someone knowing more than him) about the wood density of old growth. I figured that was more common knowledge and was pointing out a lesser-known aspect of wood structure, which got him all confused, given his lack of knowledge on the subject.

OK, I quit too.

Darn! I was looking forward to seeing how long it would take for it to be got.
