This is half way through the build and the end of the first book of installation instructions. I think the basic undercarriage is finished and next we start on the crane itself. It has taken about two weeks so far, so it should be finished by the middle of November.
Half Way Point
Note the ruler to give a better feeling for the scale of the model. The red pointer will be used to select which way the crane turns. There is a similar selector on the other side that will be used to raise or lower the support legs at each corner.
