Bike Jig

After graduating Cal Poly, I no longer had access to a bike jig which is an important tool in bike frame building. I wanted to continue this hobby, so I decided to build one myself, as these are pricey tools. This project also had another purpose of giving me many CNCed parts to make. I had access to CNCs at Bell Helmets and this project allowed me to practice machining parts with its variety of simple slider plates and cones. During this project I used SolidWorks for design, SolidWorks CAM to create the g-code, and then a Haas VF3 to machine the parts. The jig has adjustable plates to accommodate a wide variety of bike frame sizes. CNCed marking on the t-slot tubes allow me to set the jig up properly.
