Am I right or wrong about kiln dried Pine?

[paul case]

Styrofoam dust is the worst. It is sorta impossible to sweep it all up and it never rots away. Burns fast though.

Getcha some chickens.  Stupid things love styrofoam and peck the hell out of it.  It disappears.  I swear to you.  Their guts must grind that stuff up and after they're "done" with it there's no trace of it.  I'm sure on a molecular level it's still there somehow but you sure can't see it any more!  :D  Chickens....... :

I recently sawed what the farmer called Virginia red pine and it was excellent.  Straight logs with little taper.  Stayed pretty bow free coming off the saw and has dried fast and well.  We have many 16" logs coming off of a clear cut and I'll try to get as many as I can.

I did not know pine had any structure. You never see any pine being used for framing lumber here.

around here ALL framing lumber bigger than 2x6 is pine 2x4 and 2x6 are spf and 2x8 and up are syp

The consumer wants a knock down finish on the inside and brick on the outside.  They don't care whats between those surfaces.  They have neither the skill or inclination to verify quality construction relying on code enforcement.  If it falls down the insurance company will bail them out.

The builder's concern is cost and building to code.  He has already educated the buyer that knock down drywall finish is the in style, but in realty this camouflages his wavy syp walls.

I suppose the above method is ok, I just don't buy into it.

Trusses use machine graded syp as the human is not qualified to grade this lumber I guess. ???

I have a little construction job to do so dropped by a "real" lumberyard this morning.  Picked up DF studs.  A few were pretty wany but all were free of pith and most had 15 rings to the inch.  Nice and straight and generally stay that way.  A few months ago I bought some 2 X 12 DF stock for headers.  When I got it home most was tight vertical grain.  I couldn't stand using it for construction so added it to my stash for cabinet work.  Had to go back and ask for crappy 2 X 12's. :D  We don't have a DF within a 1,000 miles of here but DF is still cheaper than local plantation grown SYP.

I have to agree with MM on plantation pine.  I've never seen plantation pine I'd use even if it was free. I'm not sure if it would grade for anything but studs. It may be the right species but it ain't SYP.

Percentage of latewood has much more to do with mechanical properties than rings per inch when you get beyond 4-6 rings per inch. Look for a higher proportion of the dark heavy wood. If all else is equal the heavy stick is the stronger one.

In engineered products you'll often see an MSR stamp (machine stress rated) that is followed by an Fb number (bending strength) and an E number (stiffness). There is still a human grader at the tail end visually double checking that something like a large section of compression wood didn't fool the machine. If you look at the same stick side by side with a visually graded piece the MSR stick will have higher design values, we know more about that piece of lumber than one that is only visually graded.

For design Virginia pine falls into the group of minor southern pines listed under the MSP stamp and design values.

The latest minutes were in my inbox when I got home, think they're attached, if you want to see what they do at that quasi governmental level

Have a look at these pages for some of the construction uses for plantation pine.

Now personally I don't like pine to work with, it's soft, it's sticky and it's everywhere. But like most wooden construction, you build with what you have available, and engineer the structure to suit the material.

Good stuff Ian. It'll take me a while but I'll read it all.

Lumber from virginia pine is not considered suitable for framing and general construction in the same class as the four major southern yellow pines, shortleaf, loblolly, slash, and longleaf pine.

In the Southeast and Gulf States, the majority of SYP sawn and sold as dimesnion stock, 2x4's, 6's, 8's, and 10's are sawn from purpose grown plantation pine.  Probably 80%.  There is a lot more of it out there than people realize.  It is now what is on the market and available. 

[POSTON WIDEHEAD]

In my area Loblolly is beyond plentiful. It what is mostly used for construction material.
I sell all my Virginia Pine and White Pine for customers who like T&G flooring.
