At the risk of repeating myself, that is exactly what happened. I only noticed it after I was finished making the large spokeshave. I used a small spokeshave that I made to make the large spokeshave. I also made the saw to cut the throat and Mark Schramm made the burn auger to make the square holes for the tangs of the spokeshave blade[s] he also made.
While I was at it, I used a piece of horn from the horn spoons to add a wear plate to the small spokeshave. It is dovetailed into the body and held in with Fish Glue.
I will be teaching a class to the Nevada WoodChucks next week in Reno and we will be making this traditional tanged spokeshave. Always a fun trip.
