Why is there such a big difference at the same lumberyard?

Regarding myths about dense growth.[image]

I am torn.

It's really fun to learn something completely new!

But, I also feel a bit like "damn, shouldn't any old truths be true"...

Picked the timber myself. Same batch and sold as the same quality. Why is it so different?

A bit unlikely but it is the same tree, 75cm trunk diameter at the bottom and 13cm at the top.

80 growth rings = 4.6mm wide at the bottom, 0.8mm at the top. Not everything has to do with where the tree grows, if you want tight growth rings, you should only buy tree tops.

 

[Christer G.V.]

Some parts need to be replaced on the house due to rot, unpainted endwood. Would this not have happened with tightly grown timber?

In the past, people never painted endwood. If you paint endwood, the moisture is trapped inside.

 

[August.E]

In the past, end grain was never painted. If you paint end grain, the moisture gets trapped inside.

No, the moisture is transported out via the air gap.

 

[Mikael Thalin]

The end grain should ALWAYS be painted during repainting of the facade. Many new houses with vertical facade panels also lack treatment of the end grain, which should be fixed ASAP to avoid future problems.
If you want to be really meticulous, the vertical facade panel should also be beveled at the end ("drip nose") to prevent water from settling at the bottom edge of the panel.

This is completely wrong. The panel should be cut at a right angle, otherwise, the area of the exposed end grain increases.

Yes, it sounds likely that you would cut out a core board in an overly thick trunk block. 😆

Your conclusion is absolutely true.
However, the surface exposed to water still decreases drastically.
Therefore, a drip edge is preferable any day of the week.
The water finds it much harder to stay attached.

Water runs off inclined surfaces. Water tends to linger on horizontal surfaces.

There is often a lot of variation today as it is cut to achieve the largest possible quantities.

When working at a sawmill, we operated in a completely different way.

We always sawed planks at 50-75 mm either with the center excision (the log is centered so all the pith/heartwood ends up in a plank) or the inner excision where two planks are taken from the center and share the pith/heartwood.

Then we took outer excisions outside these CX or IX.
Then outside these, we took boards.

There was no chance that the boards would have pith or cracks.

The OP has been careful to point out that he has a high-paying academic profession. I guess your words are pure gibberish to him.

The log from which the board with pith was taken could have become really decent wall studs if it had been positioned differently and the pith was cut away.

TS has been careful to point out that he has a high-paying academic profession. I guess your words are pure Greek to him.

The log from which the board with pith was taken could have become really decent wall studs if it was posted differently and the pith was cut away.

Or maybe TS reacted to being made to feel like an idiot for having hauled home the panel pieces in the pictures. Depends a little on how you look at it.

 

[fribygg]

Or the OP reacted to being called an idiot for dragging home the panel pieces in the pictures. Depends a bit on how you look at it.

Is it common to point out that you have a well-paid academic profession if you come across as slightly ignorant about lumber?

 

[kurlakarl]

Do people usually point out that they have a well-paid academic job if they appear slightly ignorant about timber?

Perhaps it's mentioned if one is called an idiot? I'm gladly "slightly ignorant about timber," but I don't want to be called an idiot for it. I interpret the comment I received as a macho thing to assert oneself man against man, very ridiculous and infantile, but probably important among macho men in their environments, such as at a lumberyard. Sometimes you lower yourself to the opponent's level, and since he seems like a macho man asserting himself by using terms about boards, he is probably also provoked by a comment about high salary and academia. Maybe he also holds the delusion that someone who makes mistakes at a job interview at a sawmill isn't good for anything else, so he can know that's not true. If you visit me at my job, I can speak in a way you won't understand, and call you an idiot many times over. But I don't do that because it's rude to call people idiots for not knowing everything about everything.

Perhaps it's pointed out if one is deemed an idiot? I'm happy to be "slightly ignorant about wood", but I don't want to be declared an idiot for it. I interpret the comment I received as a macho thing to assert oneself man to man, quite ridiculous and childish, but probably important among machismo men in their environments, which could be at a lumberyard. Sometimes you lower yourself to the opponent's level, and since he seems to be a machoman who asserts himself against others by throwing around terms about boards, he is also likely provoked by a comment about high salary and academia. Perhaps he also lives in the delusion that someone who embarrasses themselves with their ignorance when employed at a sawmill is not fit for anything else, so then he can be informed that this is not true. If you visit me at my job, I could speak in a way you don't understand and declare you an idiot several times over. But I don't, because it's rude to declare people idiots for not knowing everything about everything.

But your response to why you chose 2 lower-quality boards started with you being highly educated and highly paid. One might wonder why...
For me, that's the opposite of an acceptable excuse, so I laughed a bit at the ironic post regarding the questioning of whether you understood any post. You haven't been literally declared an idiot. But please keep in mind that many people are not particularly impressed by an academically high-paid job. Even less so when it's used as a reason for lacking knowledge.
