In New Zealand for a conference, some meetings and a visit to my Grandchildren. This time daughter Liz asked whether I couldn't build something with the kids at school instead of just talking to them.
After a bit of puddling around, I remembered the Rainbow Bridge, and ancient Chinese type. It is made of interlocking logs to form an arch and provides a good demonstration of how you can make long bridges from short pieces with arches.
We went begging for materials and RD1in Opotiki lent us a pile of small battens. THe first trial worked well. Lashing the battens with 300mm cable ties and usng a bit of rope to prevent (or atleast reduce) sway and arch spread. I now need to dismantle it and mark it up for the kids to rebuild it tomorrow (in Opotiki) and Tuesday (in Torere). More pics as the kids get going with building.
