Are studs not made straight anymore?
Just saw this now and it seems really essential in this context. Was quarter-sawn timber generally available at one time? How long ago was that?P petlund.pl said:
I have worked at a sawmill for 7 to 8 years and now in house building at a factory for some years.
There is a big difference in some studs, some weigh a ton and some are like balsa wood and they are in the same package and have approximately the same moisture content.
The sawmill buys from many cuttings, at the mill it is sorted into, e.g., 20 different thicknesses/classes for each type of wood.
Class 10 is sawn to 50*125*2, dried, and planed to 45*120, so your 45*120 studs can come from 5-20 different places. (Class taken just as an example)
So one stud can have cm between the annual rings and the next so close together that you can barely see where one starts.
At the factory I am at now, we always cover with plastic if we bring in studs, and outside we also have wrapped packages; if we open one and take a bunch, we cover and tape it.

There's hardly much timber sold in any metropolitan area that has been harvested locally. Here in Stockholm, I've seen that it can come from Hälsingland and the Eastern Bloc. There are plenty of places that have core pine in stock or can bring it in and mill it to what you want.F fribygg said:
Yes, as it has been explained to me, the industry does not saw "fine wood" at the same sawmill, and there is no sorting of the logs in such a way that particularly fine wood is sent elsewhere. So the problem is not that there is a lack of extra fine wood, but that the percentage that comes in is not sorted out, as at a smaller sawmill.nino said:

I would probably claim that quality timber grows in large parts of the country.
It's more about the right growth site, the right soil, etc.
And then sorting it out.
I dare say that the Skåne pine is hardly suitable for outdoor furniture, but the Gotland pine could be suitable..Huddingebo said:
No, exactly, a little sorting is done but it's more for flooring, laminated wood, etc., not furniture wood.C cpalm said:Yes, as it was explained to me, "fine wood" is not sawn at the same sawmill within the industry, and there is no sorting of the logs in a way that particularly fine wood is sent elsewhere.

I myself have only had my own forestry and sawmill for a quarter of a century, so I have to defer to the employed carpenters who use sparse paneling of spruce where heartwood pine or oak would be more suitable...M mats.3 said:
I am absolutely willing to test the sawmill industry's 28*70, but then it will be protected just as sparse paneling in the ceiling, then it is a suitable, cheap, and readily available choice.
How did we go from selected heart pine from Skåne for outdoor furniture to industrially sawn spaced paneling in spruce?F fribygg said:
