I’m a bit annoyed with my self got to take more time slow down. I jumped out of the Knife wall and marked wood. Also bottom housing/dado not as nice as I would have liked. Grain going different directions one housing/dado had two knots in it.
Finally got around to making one. The lower 45° angle still needs to be cut, but this should suffice for making christmas stars. I used what pieces of wood I could find, so the dimensions differ a bit from the ones @paul-sellers used.
