They cut really thin curlies in anything else (well, I haven't tried
aged oak, yet), so I think they are pretty sharp (SCARYied, just before
use on this piece--and duringG). It has to do with the angle of
attack, and the wood itself--plane geometryG.

George noticed that I mentioned it was CCA--does the metallic content
of the tx have anything to do with the hardness, or is this just badass
wood? (BTW, I know that SYP is hard; my query was to reasons for this
characteristic. Resins, age, tx? Combination?
I'm gonna find a different board.

We have a northern non-pine that is similar to SYP - it's called Tamarack,
and it has most of the bad qualities that SYP has in the way of excessive
resin - which was _not_ set in drying, because you can't do that when you
treat it. It has a high SG, even though it's one of the fastest-growing
trees that grows here for the first 25 years , and barely capable of being
dented. Great mine lagging.

I suppose everyone knows what rosin is, and what it's used for? Then
there's aged rosin - amber, I think they call it.
