Making molds is fairly straight forward modeling technique that is not too tricky to learn. One of the simplest methods I have found in the literature is on the Composite Structures Technology (CST), website. It is very similar to the techniques I use when I make mine. Go to their website and look under Mold Making, where they describe building a simple female mold for a cowl. Extend the method to your canopy<BR>

As you get more experienced with the mold making technique, "clamshell" molds for making propellers, landing gear, spinners or other more complex parts, are also fair game. Hope this helps<BR>
