while i was pondering over the supplies i needed to buy to make this, i came over a little improvement in your design.
first, drill the top hole about 1 1/2 inches deep. then drill the side hole 1 inch from the top, so the top hole goes down further than the side hole. do this for both batons. then take your loops, and push them into the top holes, so that the end of the loop is pushed all the way down, so when you look through the side holes, you cant see anything. now you might be asking "what about the sides of the loop looking through the side hole?". well my answer is simple. make the top hole wider than the side hole. the whole objective here is to make it so when the loop is in, and you look through the side hole, you dont see it. the reason for that leads to my improvemtent. instead of using a screw, which could rattle abound, or possibly hit you and cause injury, buy a thin wooden dowel that is the exact same diameter as the side hole. cut the dowel into small sections equaling the diameter of the baton. force the pieces into the side hole. then, just sand it to contour to the dowel's curve, and youve got safe, better looking detachable nunchaku!!!!!

feel free to ask me if you are uncertain about anything i just said.
