CNC turned billet 6061 bar stock into the single-sided spindles that utilized existing, but also modified, Lefty Si hubs. Turned components were machined on a Haas TL-1.
MasterCAM toolpaths. Programmed for re-machining wheel hub to fit custom machined wheels. Modifications to off-the-shelf parts were machined on a 3-axis Haas TM2.
Wrapping an aluminum structure with 3D printed SLAs. 2 halves adhered to make up the handlebars.
Pre-paint.
