I cut the tone board and the wedge in my jig, use my router for the tapered portion of the channel and glue the pieces back in that I cut out and turn to size between centers and finish the portion from just past the wedge block on the exhaust end with C A if that is what I am going to use for the finish , then pop the wedge block off , then I chuck up in a collet chuck drill out the center hole as I want and then finish turning the stopper end and finish it and then pop off the glued piece.
