The prototype, which has performed very well these past months, is pine. The new version is mahogany, a harder wood that I appreciate more and more and I learn to work it. There will be a new home for the prototype. And no, not the burn pile.
It occurs to me that without a tail vise, I probably need a sticking board for these types of tasks. I did devise a way to hold down the work to cut the rabbets, involving a scrap of wood, some sandpaper backed plywood and a holdfast. So, basically, a sticking board.
Doing this project showed me that fine, cross-grain shavings may bind in the throat of the plane. I’ve looked at other examples, though, and the throat size doesn’t seem to be drastically out of the norm.
It’s just something I’ll learn to live with, I guess.
