Subject: Pole Frame Workshop

What is the Strongest Timber which can be milled from any given log?
Answer: less than one-third the strength of the log according to tests at
the US Forrest Products Lab (FPL) in Madison, WI!  Pole framing is more
than 300% stronger, and hence lighter, easier to build and more sustainable
than timber frame, let alone stick frame construction.  When we process
wood, as with food, we take away its strength, and waste energy, labor, and
materials while tripling even quadrupling its cost.  This is only a small
part of what you will learn at an up-coming Kickapoo Sustainable Woods
Cooperative <[EMAIL PROTECTED]>  on pole utilization workshop to be
held Saturday,  August 17th near La Crosse, WI.  The cost is $10 for
members and $15 for non-members. Please contact Paul Bader
<[EMAIL PROTECTED]> (608) 625-2515 to make yours soon.  Space is limited.

In the morning Mark Knaebe <[EMAIL PROTECTED]> of the Forest Products
Laboratory (FPL) in Madison WI (http://www.fpl.fs.fed.us) will present a
slide show about some of the recent work at FPL in engineered pole frame
structures and connections being developed there.  

Our host, Architect Roald Gundersen <[EMAIL PROTECTED]> will then give a tour
of his house, studio, greenhouse, barn, and stream house, all of which are
through-bolted pole-frame stuctures, three of which utilize straw as
insulation. All of the structures use forest thinings of less valuable
trees, leaving improved stands as another benefit of pole framming.  

After your brown bag lunch, interested parties can participate in errecting
a curved pole-frame addition onto Mark Harrell's home half-an-hour away
near De Soto, WI.   Mark lives in the second pole frame, straw bale
insulated home.  This addition uses curved poles and walls further
strengthing the materials.  Gundersen uses wind-damaged curved trees  to
brace his buildings, branching trees columns and crocks for supports and is
working with an orchardist to grow trees into structural shapes for
curvalinear pole frame buildings.  

Participants who take time to look at the links on the FPL web site will be
that much further ahead:
