Nice work jim-I know what you are dealing with. Making those drive dog ears on the pad adds a lot of machine work. I spent a week+ making one pad perfect and that is why I made a mold and cast all of them. I'm sure you noticed the pitch changes as you transition from flat to the circle and that was the tricky part for me making the drive sprocket. Never got it exactly right. Looks like you have it figured out. Keep the pictures coming.
