I am using hardwood shoes and am having some trouble with this process and would like to avoid going back to softwood. As well, the question I'm asking is not discussed in your web technical. Unless I'm missing something, you simply say run the drill backward to center on the pilot hole and drill through the hornbeam. This will give you a hole the thickness of the hornbeam bushing. If it fits the pin precisely it cant pivot freely, so the hornbeam has to be relieved from the inside of the mortise. 1 How are you relieving the hornbeam from the inside to create a "funnel" shaped hole 2 (This is question that's tripping me up) in creating that funnel shaped hole, in order keep the hole at the bottom of the key a true circle fit precisely to the pin, the hole has to have no depth, ie the funnel has to come to a point at the bottom of the key. I don't think this is what you are doing as the hole would be elongated in quick order. On the other hand, if you leave the sides of the hole straight for 1-mm or some amount to give the hole some meat before it is relieved, then you have to introduce slop into the hole to let the key pivot. slop = clicks. how are you achieving the necessary freedom of movement and the snug-ish hole?
