I've been having an email discussion with several model railroaders who
are convinced that wood changes length with humidity. It must, because
their track is developing kinks :-).
I've quoted websites and books that prove they're wrong, but it doesn't
faze the true believers. Seems politics and religion aren't the only
areas in which opinion trumps facts :-).
So, have you sold them a januwine Wood Shrinking Unit yet, LB?
OK, it does move a little - according to the wood handbook 0.1%-0.2% from
totally green to over dry. That's about 0.1" in 8'. And I doubt they're
using green wood :-).
OTOH, some of the same folks are convinced that Homasote (a pressed paper
product) does not move from wet to dry.
You meet the nicest people on a keyboard :-).
Say "Halelujah!" and pass the mashed potatoes.
P.S: It's nice to know that the Wreck isn't the only source of cracked
info.
