This is the little hub you would need if you built a Spinning Janny Kite. It will support 3,4,6, or 8 symmetric spars, insert spars as you need them. It is designed for 3mm kite rod and will likely work with 1/8" rods as well. Tie a large knot on the back of the hub and attach it to the kite line with the best fishing line swivel you can find. Fun to fly, enjoyed by all.
