| The John Lee Top Plug Photo by David Johnson created 8/15/2002 submitted 11/11/2002 12:37:18 PM This photo shows the top plug for Yale's 2003 ASC entry, The John Lee. This photo was taken after machining and before surface finishing. The plug was sanded to a smooth bare-foam finish, then any defects were filled using a short-hair fiberglass autobody filler. It was then painted with an epoxy primer-sealer. Following this coats of primer-surfacer were used and then wet-sanded off to create an automobile quality finish on the plug. Then the plug was sprayed with a final primer-sealer coat before waxing to prepare it for the molding process. | |

| The John Lee Top Mold Photo by David Johnson created 11/7/2002 submitted 11/11/2002 12:22:32 PM This photo shows the completed top mold of Yale's 2003 ASC entry, The John Lee. The mold was made by spraying chopper glass on top of a foam plug. The members in the picture are washing the PVA (a release agent used in the mold making) out of the mold to prepare it for layup. The mold is supported by a metal frame in order to provide support for the weak chopper glass mold. Metal was used rather than wood to allow for high temperature cures. | |

| Team Lux Shipping Crate Photo by David Johnson created 7/10/2002 submitted 11/15/2002 07:22:33 PM This photo shows the structure of the shipping crate Team Lux used to send its stack of foam out to be CNCed into the top plug of The John Lee. The bottom of the crate was the torion box used to support the foam stack. The foam was glued directly to the bottom plywood skin. The top of the crate was covered with plywood to prevent damage during shipment. The crate (torion box and top) without foam weighed 1400lbs. Total shipping weight was 3600lbs. | |

| Detail View of The John Lee Foam Stack Photo by David Johnson created 7/12/2002 submitted 11/15/2002 07:37:36 PM This photo shows the foam stack for the top plug of The John Lee inside its crate shortly before shipping out for machining. The photo clearly shows the disadvantage of using epoxy for gluing foam blocks together. The low viscosity epoxy ran out from between the blocks and coated portions of the next layer of the foam stack. Ultimately this caused no problems in machining, but it wasted glue. | |
