Prototype Development

The Late Bird, a new project.
This time, I wanted to try using plywood to create an automata and produce a kit of parts for others to make. Being a new material, I was faced with new challenges. In particular, I needed to develop a new approach to prototyping.

Making models from plywood is a time consuming process, The cutting out is both harder and less accurate than with cardboard. At the Frankfurt bookfair I was introduced to a new (to me) material; foamboard. It consists of a thin sheet of foam sandwiched between two layers of heavy paper and comes in thicknesses ranging from 3mm upwards.

The clear advantage this material gives me over the use of plywood is that it is so easy to work with. It cuts easily with a scalpel and can be drawn on with a pencil. After the first stages of prototyping I found that I could use the computer to design and print parts, spray mount the parts onto the foam board and then cut them out.

I went through various stages of development before settling on the above model. Initially, it didn't actually work: The worm failed to return into his hole. I hoped that this was because the foamboard lacked the weight of plywood. I also found that the gears refused to mesh correctly. Again I hoped that this was because of the 'give' in the foamboard. I was wrong...

Having arrived at a first draft, all the parts were saved into two files each of approx. A5 size for emailing to Trilogy Laser Craft.

Time to wait...
