Reverse Engineering

During the high school Intro to Engineer and Design class, we received the assignment of reverse engineering a product of our choice. My partner, Hunter Bjork and I, Leonardo Salinas, set out to reverse a Solids brand longboard. We have completely disassembled and digitally recreated the longboard of choice. The actual board and the digital rendering of the board can be seen on the left and the main components of the board can be seen below in two pictures. Detailed renderings and real pictures of the parts can be seen on the Reverse Engineering page. This page also includes the mass properties for each part.
