[Public-List] Old Hickory

[Michael Grosh]

That's a heck of a chart, Bob. I read it as spruce being 1/2 the weight,
and 2/3 compression (resistance?) Of white oak approx.
So I suppose spruce being bendy is desirable in masts (racing dingys,
etc.). It's a pretty spiffy wood for a pair of 9' oars I have also.
Scratch the spreader idea. Maybe that's why later boats are in aluminum.
