OK, wood hasn't changed much, but what adhesive are they using? I didn't see
that mentioned.
I'm under the impression that modern epoxy (like West Systems) is stronger
than the parent wood .
That would make a laminated beam a much better idea than this study seems to
show..

Dear Ron,

It doesn't matter WHAT glue they used, it would still be stronger than
the softwoods we normally use.

This is kinda like the Horsepower Myth, where everyone goes around
citing HORSEPOWER when they should be thinking in terms of torque and
thrust.

So your epoxy is stronger than your wood. Big deal; so's casein, hide
glue, Plastic Resin and even Elmer's vinyl resin. The point here is
that we don't pick our adhesive for it's STRENGTH but for some other
characteristic.
