Someone asked me to post these...




3" pieces of all-thread, sharpened on one end, tapered to fit in the boo shaft on the other end, drilled a hole at an angle to the tip and bent a finish nail through it. then ground the threads off the center " and drilled a hole for the string to tie on.
You can kinda see the angle of the nail and the center holes. I havent tried them but I'm not too confident in the design...
