RWL Posted February 8, 2022 Share Posted February 8, 2022 (edited) I didn't find much here on how to make the leather beads that connect the arms to the pads. This is what I came up with. The beads on my Edeophone measure about 3/16" diameter and the hole in the old bead is about .063". A #52 wire size drill makes the right sized hole. I used a 3/16" punch to make plugs from an old belt. Now - how to hold the leather plug to drill a hole through it longitudinally. Hmmm. I clamped two pieces of wood next to each other and put a hinge on one end so I could open and close the two pieces, sort of like a nut cracker. Next, at the crack between the two pieces I drilled a 3/16" hole into the wood to a depth of the belt thickness. It was too loose and the plug spun when I tried to drill it. In the end a #16 drill made the right undersized hole to keep it from spinning most times. With a #52 drill bit centered over the plug I got about a 50% success rate with a fair number of off center holes in the plugs. Those little drills tend to wander when starting the hole and bend enough in the leather that the holes wander to the side. The plugs still occasionally spun even with a light feed on the drill. Drilling from one side, flipping it over and drilling from the other side helped a little, along with a light pecking feed but it was slow and the success rate still was no better than 50%. What worked was to make a drill guide to center the drill and compress the leather from the top. I used a 3/8" dia cylindrical piece of aluminum with a short section at one end slightly smaller in diameter than the hole in the wooden "vise" and a hole through this guide to center the #52 drill. In practice, I put a clamp to hold the wooden vise closed, and with my hand I firmly push the drill guide down on the plug in the wooden clamp and then slowly drill through the bead. The drill stays pretty well centered and I don't think the plugs are spinning at all. There is a little tear out at the far end but that can be nipped off with wire cutters or a razor blade if you want. It would probably be lessened if I slowed the rate at which I advanced the drill bit. How do you make beads?
