Tenshodo 14:1 Worn and Wheel : I needed a Tenshodo type 14:1 worm and wheel for the current project I'm working on. The Tenshodo's were about the right size and would probably do the job, but a preference for metal gears prompted this sub project. The one thing that this blog demonstrates besides novice gear making, is how much time can be spent making side tracked components before work can begin on the job in hand. Now that the gears are complete, changes have been made in the main project that may render these gears as unrequired, we will see.
