Spin Mold

During my last semester as an undergraduate at Brown, I took a class that granted its students access to a large ShopBot CNC machine. After witnessing how accurately the router could machine parts, I decided to design a spin mold to be used in glassblowing. Spin molds are used to shape glass by blowing a hot glass bubble inside the mold while spinning to maintain symmetry. Any irregularities in the mold will cause the glass bubble to bind inside the mold. The idea of making a spin mold had crossed my mind previously, but in order for it to work properly the inside of the mold must have near perfect radial symmetry. The CNC machine made it possible to achieve this level of precision.
