Lindsey over the road has a big back yard. My family as been coveting his land for some time now. Finally I decided enough is enough, and began to plot the annexation of number 5.

In the original style, the counterweight stood back up, as it was composed of people. Once the Europeans got hold of it, and started making fixed counterweight versions, they used a winch of some sort to haul the throwing arm down.

I suppose they might even use some sort of block and tackle arrangement, likely powered by draft animals.
