   I usually figure 2X lumber at about 40# per cubic foot. That means a 2X4 will weigh somewhere around 1.5# per foot.

   So a 16' 2X4 would be about 24#.

   I was thinking the same thing, Paul.  Sounds awful heavy for KD.

   It's just a rule of thumb for KD lumber. I think it's actually for SYP lumber, so SPF may be lighter. I have no idea what green lumber would weigh. No one around here sells it, and we obviously don't use it for trusses.

   All I know is lumber seems to be getting a lot heavier as I get older. <G>

   It varies a lot.  Here in DF land, the heaviest pieces seem -- and this is just from picking them up, I never weighed any -- to be almost twice as heavy as the lightest ones.  The old handbook value for DF is 37 pounds per cubic foot.  That's a worst case number for designing structures and loading trucks.

   John, how about Glulams?  They are fir and larch so your 37 lb might be about right?  I think I heard a number like 30 or 40 and don't remeber which.

   I checked the copyright date on that handbook, 1948.  So it might not apply to glulams.  Try the manufacturer's web site first.
