Some of the construction footage compiled:
Assembling the uprights:
Building the rings. Unfortunately no pictures were taken of the process where we lifted the rings onto the axle. About 10 people lifted each ring, while I stood on the top of an upright to manipulate the axle into place. Someone on the other side of the axle pushed it through, while another couple people held a crutch in place to support the weight of the rings and axle. This was repeated about 6 times, because we had to remove two of the wings to widen the holes in the plywood.
Some other of the courtyard structures. In the background is most of the four-story fort. To the right, part of a ride called the "Frosh Wash", and in front to the left an impromptu swingset.
Before we put the plywood and climbing holds on, we found a bunch of fun activities to do with the structure:
The climbing actually worked well. We found a brake position that worked for a fairly wide range of climber weights. Two people on the sides of the cylinder would help turn it to make sure no one climbed too high up.
