Part 4. More work on integrating the sub-frame into the aerodynamic fairing and the main drivetrain section. Using Freeman 1020 Low-Density Epoxy Molding Compound (aka...Cookie dough.) we got some very nice results but note, do not exceed the 1/2 inch thickness spec unless you have a really good way of dissapating the exothermic heat this stuff will generate if you go any thicker. (that was one of the reasons for using thick aluminum plates in our clamping rig. they act like a heat sink to keep the heat manageable.
