Thank you Erik at thebicycleshopinc for showcasing one of your favorite processes on our lathe. “Erik doing one of his most favorite lathe operations. Cutting a keyway inside of a drive gear on a special needs trike. The gear was held on the axle with set screws and had spun from the torque. An axle key will do the job.” . . . thebicycleshop_wrench sebastian.fraczyk iamspecialized #machining #machinist #southbendlathe #bicycle #bike #bikemechanic #thewolf benbarbarian
