This is the 3rd call I've completed and they seem to getting easier/better sounding. I keep bouncing these off on friends for input, that helps a lot. Sorry for the quality of the pics but I forgot to take shots of them before it left my shop so I had to settle for a cell phone pic. Slate over glass made from a piece of Sugar Maple I took down a number of years back, the striker is Maple with an Oak dowel.
Working on 2 more and hopefully they will look better than this one when they are all done.
