http://www.chicagopaddling.org/klsled.jpg is a klondike sled we built that
gets a lot of stress (kids running pulling the rope or pushing it from
behind). There is the outer layer of PVC, however there is also a inner
layer
of pvc inside it that is connected to the outer layer via sheet metal
screws.
All the other sleds were made of wood and if you look at the picture,
you'll
see just how far behind the other people were... they changed the rules
the
following year and our plastic sled was banned... :-(

Also, http://www.chicagopaddling.org/wind2.jpg is a windmill mounted on
top
of PVC pipe... in that case we used multiple pipes with bolts going thru
them
to make it easier to disassemble (I'm a scout leader, and rather than
burning
propane lamps at night, we used a windmill to recharge a small battery and
had 4 automotive dome lights inside the dining fly for lighting at night).



Ahh, the modern Boy Scouts. Gone are the days of 'wrap and fap' and making a
fire with one match. Now its klondike sleds made of PVC, and rechargable
batteries. :-)

How times have changed....do you still carve little boats out of bars of
Ivory soap?
