Cody they look so good I'm gonna try some. Heres' a thought put a straight pin through that has a hole in each end. Make two rings ( like on a key chain) and on the rings (small ones) put a cone on each side so the cones hit the roul and gingles. The screw way just thread the last 1\4 in. and trim flush. Love the course files, could sell them to all the ferriers.
