I.     Initial Design Methods + Trials

A.     System of Stacking Masonite Trays

Based off of our previous system devised for our analog machine. At this scale (15″x30″ inner bed dimension), the masonite, even laminated, was way too flimsy.

C.    Unparalleled trays

After assembling the outer box together, we started to put together the different trays. The box consists of 4 magnetic trays that are attached to pulleys and one middle tray that holds the main flexure pattern in place. Our first attempt with the interior trays failed for various reasons. The 4 outer bars that are there to keep the trays straight were supposed to fit tightly within the holes in the trays yet, due to bad calculations the designated holes were too big which stopped the trays from moving up and down horizontally (see pictures below). As we would push the trays they would bend in part also due to the poor pulley system put in place in that attempt. The pulley system consisted of 16 pulleys attached to the inner faces of the box, a cable with hooks that would attach to trays and supposed to move them simultaneously. Yet, the poor choice in hardware did not help with the lack of horizontality of the entire system.
