I’ve always been drawn to the mechanical aesthetic of motorcycle parts and began building functional art out of old moto and bicycle parts. I had the idea to use a motorcycle throttle to actuate the lamp mechanism. These throttle lamps are a blast to build. It took a couple iterations to make it work well. A 90 degree throttle assembly was used so the cable would run parallel to the lamp shaft. The lamp mechanism works better when the pull cord is pulled 90 degrees to the body so I turned a piece of delrin plastic down on my lathe to use as a pulley. Another delrin piece joins the pull chain to the cable. A throttle has to snap back to give that nice, crisp feel so I worked in a spring to return the mechanism. The lamp shaft clamps on to the base with a shaft collar so it can be removed to assemble the throttle assembly. This one uses an old sprocket, brake rotor and transmission gear as the base. Some extra transmission gears were added to the lamp shaft to add some more mechanical flair. Definitely a conversation starter piece!
