Introduction

  Disassembling the Raider CS-35 Nerf Gun was the first teardown I took on independently. Earlier during that spring semester in my sophomore year at Tufts, I had walked through a formal teardown of an electric can opener with a team of 3 other students in our engineering design class. We disassembled and reassembled the product many times, compiled a bill of materials, modeled all the parts in Solidworks, compared the product with similar competing products, and then presented a final presentation on our analysis of the product. This month long process was much too intensive to be easily repeated on my own time, but it inspired me to disassemble and reassemble other manufactured products.

Notes

  The plastic parts appear to have been produced using an injection molding process given the high surface resolution and ejector pin markings. It was also interesting to note that all moving parts were somehow involved with a spring. The variety of actions that were made possible with springs alone was impressive.

  The disassembly of this nerf gun was straightforward, requiring only some needle-nosed pliers and a 3 mm philips screwdriver.
