(click each picture to enlarge - this is your last reminder)
So the first thing we needed to do was revisit the Arthur Church illustration. We went back and drew more precise sections and figured out how to remodel the flower to focus on the areas we were interested in. We figured out a scale for the drawings based on how thick a sheet plastic would need to be to accurately represent one layer of flower-material (in this case, a sepal of the orchid). These serial sections were made to show off the interior parts we are interested in and a couple were blown up to full scale (the full size versions of the images in this post are 24" x 36").

So the next thing was to take this stuff and turn it into plastic. Specifically, plastic sections that can be made with a vacuum former. This process is basically making a mold that has a vacuum hose attached to the bottom of it and pulling heated drooping plastic into it. This drawing explores breaking up the model into several pieces, as well as different ways of joining the pieces. The idea is to build joints into mold so that mechanical processes are not required to hold the model together. Another issue with vacuum forming is that the exposed edges of the plastic cut out of the mold are not very nice or clean. So these kinds of joints minimise exposed edges giving a smooth surface. The grey diagrams are our first attempt to work out the section of the mold.
This is an axon showing how the different pieces currently go to together. The second from left is the total assembled model. This drawing is lacking details about connections, but those will keep getting updated throughout the quarter.
Hopefully these renderings will help put it all together. It's a little confusing, but that's one of the things we need to work on. There are a lot of things to work on, so hopefully much will get clarified in the next few weeks.
