Making tools from the tools you already own… This almost sounds incestuous – almost.
This is the next phase of our fairing construction for the University of Central Florida’s 2007 Human Powered Vehicle. Here we will take a positive male mold and begin making a female negative “tool.” We call it a tool because it can be used to make many duplicate copies. This tool is in fact a negative female mold.
To reiterate, this whole project is daunting. However, each individual step is not too scary and within the capability of most people handy with a few simple power tools. On the other hand, the price tag is scary. For this half alone, we used 5 gallons of polyester resin (circa $130).
