excuse the partially off topic subject, but I'm looking for a little
input. I'm looking to scale up a project by 50% (all wood) does anyone
have any general pointers, i.e. Do I use 50% wider ribs, or is this not
always required?</SPAN></FONT></DIV>

are the forces on ribs? Is there much of a crushing force or is it mainly
in the fore and aft direction.</SPAN></FONT></DIV>
