DRAM 160 Lecture Notes - Lecture 2: Connect Four, Proscenium, Rigging
Document Summary
Build stuff to be able to put up and take down every night. Spot line system/hemp system: takes rope and using a bag of sand to counter it. Scenery will be a little heavier than the sand bag. Batten that is held by 4 wired rope and needs to match the contour of the floor. Rope goes through and is connected at a pully at the top (and connects the wired ropes into one) and at bottom. Double purchase system: 2 loops above and under the arbor. Use 2x heavier arbor, but only need to move it half the distance. Pipe weight: how much is need to balance when the system is empty. Tension block (floor block): keeps rope stiff in case it wears. Head block: where all the wired ropes turn down to go to the arbor. Loft blocks: wired ropes go up through this and towards the headblock. Motorized: controlled by motor, turn on and off.
