089. Revolving Crane
The series almost ended with this model. The crane assembly was too fragile to handle any stress, or even the weight of the bucket. It took quite a bit of work (and a little Stick-Um) to get everything to stay in place.
You may notice an extra piece at the top of the tower. That was necessary to keep the crane assembly from toppling over backward. Because of the horizontal dowel anchoring the crane, I couldn't use a vertical dowel to secure the assembly. A little tape in the back did the trick.
And I won't even go into the problems trying to thread the string through all the points of contact while trying to hold the rickety thing together!
