The Mold’s Here!

Bobby contacted the foam company to order a laser-printed, styrofoam, female mold. The company used the CAD drawing exported from the FreeShip model of the final hull design to cut the shape into several blocks of styrofoam. The turnaround time for the mold, once ordered, was 2 weeks to make the mold in Ohio and 2 days to ship it to TCNJ. Bobby and Jeremy picked up the mold in the Decker Mail Room on February 27th. The mold came in two wrapped bulks as seen below.

With the help of a TCNJ maintenance worker, we loaded the mold into a TCNJ van and made two trips to deliver it all to STEM where the canoe will be constructed. The mold was unpackaged there and was reconfigured to the actual shape as shown below

The team is eager to start the construction process and begin mixing the final concrete design

Preparing for Construction

Mix materials transfered from Armstrong hall to the STEM building with the help of Mike Steeil

Before the end of the fall semester, we spoke with Mike Steeil about what materials and supplies we needed to transfer over from the Armstrong lab to the STEM building as Armstrong hall will be closed for renovations. Over winter break, the team discussed the plan for the spring semester and more specifically about the construction of the canoe. We compiled a list of what we already have and what we needed to order. We needed to order a bag of type I cement, elemix, carnauba wax, fiberglass mesh, and other miscellaneous supplies to start construction. Insulation foam was also orderd to be fitted into the ends of the canoe for flotation. The materials were ordered to the Ewing Home Depot for pick-up. While the team waited for mold to be delivered, we began practicing our final mix design in the mixing bowl to ensure the right proportions.
