Spring 2018, Week 1: Finalizing BOMs

January 24, 2018

Coming back from Winter Break, the first order of business for the entire Small Scale Superway team was to finalize the Bill of Materials for our respective sub-teams. The Track and Manufacturing team searched the shop for materials to lower the final cost, but could not find useful parts. As such, the final BOM came out to $1447.11. This can be seen in Table 1.
