Winter 2007 Class Five Pictures

Our fifth indoor workshop for Feb 2007, run by the Dry Stone Wall
Association of Canada, went extremely well. Landscapers from London
Ottawa and Haliburton learned how to do some difficult walling as
they attempted to do this twisted dry stone rubble helix. It stands
10 feet tall and is completely self supporting. The centre rungs
each weighing over 300 lbs , laid 12 inches apart, twist nearly 90
degrees over a central axis. The columns step out and around each
other well beyond their original foundation footprints. The structure
looks impossibly unstable but it is remarkably rigid. (We had to
climb all over it during the raising of each massive 4 inch thick
ladder stone) If the heating pipes had not been there we would have
liked to have kept going to complete 180 degree or even a dazzling
360 degree rotation. But for now, there it stands until the next
attempt.
