Looks interesting, love engineered gadgets/jigs... is there an indexing component to ensure you don't overshoot a tip? How is the blade kept steady?

Duckie... at the moment there's no indexing. I'm thinking about how to do that where it works with various teeth and spacing between each. At the moment I move the sled back, rotate to next tooth space or gullet, move the sled forward, touch grind. Repeat and rinse. I move the sled with two hands and use my thumbs to temporarily hold the blade while touch grinding. If you have any ideas of indexing I'm listening.
