Jerry Kieffer made this throttle cable for his 1/8 scale model Harley-Davidson motorcycle. The cable was made using a special fixture, which was designed and turned on a Sherline lathe. The lathe was also used to wrap the wire for the outer cable using the same fixture. The inner wire that actuates the clutch is .010” in diameter and slides freely within the outer cable housing. The housing was wrapped using .007” wire and has an outer cable diameter of .032”. It took several attempts, and weeks of work, for Jerry to design a wrapping fixture that worked—but the final product works very smoothly.
