Quarter sawn lumber explained

For a few of us that need a simpler explanation of quarter sawn lumber
and why it is more expensive,

This method is labor and time intensive.

And done another way in a more wasteful manner.

They touch on it a little in the video, it requires a much higher quality
log. The reason for this is very little high grade is extracted from the
center of an oak log. Hence the origin of the grade FAS, indicating First
And Second cut of a log.

Generally when flat sawing grade oak lumber the core material is dropped
out as a 7x9, 6x8, 6x6 etc. The lumber goes to grade markets and the cants
for ties, dunnage, resawed for pallets or a thousand other uses.

In quarter sawing the mill has to deal with a lot of low grade lumber from
the core and/or purchase higher grade logs, either choice runs the cost
up.

Industrial green hardwood markets consume far more hardwood than
the grade lumber markets. The demand for railties greatly enhances the
price of flooring.

here's another example ..

.. but it still seems to me that a good percentage of a straight
sawn log - would classify as quarter-sawn - the middle 2 - 4
pieces.

That's so altho it's not a very large percentage...it's computable from
log size depending on how much diagonal one wants to allow in the
discernment of "quartersawn" or not.

Need GMO trees that grow square corners and concentric square growth
rings to maximize yield... :)

By "log size" I refer to the fact it's a fixed ratio assuming the
hypothetical round trunk, and a given maximum allowed curvature, not
that it is actually a variable percentage by the physical size except in
total volume.

Once't upon a time I recall there was a flurry of work to try to grow
"square" melons and such to make shipping more efficient. I don't
recall having heard much about it for a while... :)

I speculated here some time back that the day of adhesives in woodworking
would end... grow the shapes you need and let them grow together into
finished products. ;~)
