Nice! If you want to be a toolmaker and figure out the indexing, I’d buy one. I currently have three circular saw blades sitting in the “once I find a local saw sharpener who doesn’t suck…” pile.
Dave.... indexing is a complex thing and the question has to be asked if it's really necessary. It would be nice but if the jig is used to sharpen many different saw blade tooth patterns and spaces then the indexing becomes woefully painful. Then it may warrant multiple separate indexes or one complex one.
I've looked at indexing and don't see a way where it is simple and efficient without entering into a realm as mentioned above.
For now I'm adhering to a phrase one of my Engineering profs once told me many years ago....." Remember KISS!" (keep it simple stupid).
I'll see how it goes.
