They look great, but erm... won't those tubes come flying off if you start spinning them? Are the caps the only things holding the rope to the tube?
This is how my friends and I are making nunchaku. It's very easy, no knots sticking out or drilling. Little hardware, no tape, no bolts, very pro looking!You can also use wider tubes with a longer rope, or a chain secured under glued end caps to make Korean nunchaku very well, almost exact to them!I hope this helps you guys make nunchaku easier! http://www.youtube.com/watch?v=9Timi_y09ec&feature=youtu.be
