[bolger] Re: #1 southern yellow pine (shortleaf pine)
To Phillip Lea
The stuff is loblolly pine, or a few related species. Like any other
wood species, you want slow growth stuff, very narrow rings, and
sometimes picking through the pile will produce that. It has about the
same resistance to rot as fir, that is, not much. It holds paint quite
well. Internal moisture blows paint off house siding. Probably every
house in Dixie had pine siding down to the fifties. Old pines have a
resinous heart that has very high rot resistance because it is moisture
proof. That makes it epoxy proof too. Some varieties, such as in my
area Virginia pine will be superior spar material if you obtain young
sapwood, but it is very hard to find clear and long. You just have to
know what you are looking for. Books are no help.
All in all the Southern pines are very individualistic wood, and are
something of a connoisseur's material. In salt-treatment yards I have
seen trash and perfect planks on the same stack for the same price. I
have seen some pine plywood that looked to me very high-grade stuff,
but that's another subject.

Phillip,
I have used some southern yellow pine for framing on a couple of boats. I
find it heavy, splintery stuff, almost as bad as oak only uglier, but it
glues well with straight epoxy after some roughing up with coarse sandpaper
or a rasp. I couldn't hazard a guess as to species of the stuff I used.
Based on a few years of continuous exposure, the glued joints haven't failed
and the wood hasn't rotted. I've painted it with alkyd enamel after a couple
of coats of epoxy, and the paint holds up well for me,

Lumber yards sell it as #1 southern yellow pine -- the specie around
here is acutally shortleaf pine - plentiful in my area, therefore I can
afford it, and there's plenty to pick through too. At least as strong,
denser, and a better grade, albeit heavier, than the almost
non-existent douglas fir. Local builders state and observation
confirms that it doesn't hold paint well on home exteriors. But Reuel
B. Parker and others use it in boats - and it has been mentioned
recently in this group. What is the broader experience? Does epoxy
work well with it? Are there certain paints that work better than
others? What boat parts are most suited to southern yellow pine? Does
pressure treating affect epoxy or paint holding ability?
