For some kites, but mostly for kiteline-decoration that rotates, you need a whirl. Whirls are also used by anglers. At our hobby there is often much more linepull, so it must be a strong whirl. I build this whirls out of aluminium and use them with my Revolver-Kite, my Knüpfer-Snake (see picture) and other rotating kiteline decorations. |

The whirl consists only out of two
Aluminium pieces and a two sides closed ball bearing. Dimension
of the ball bearing (German Norm): |
 |
To mount the parts of the whirl together I build a tool out of steel. The smaller one takes the mounted parts, the longer one is used as beat stamp. |  |

Aluminium case. The ball bearing is not mounted yet. Right: Now the three parts of the whirl are plugged together. At next the tool is used. Whith some strong beats of a hammer the ball bearing is fixed. |

Left: The ball bearing whirl is
finished. I used some of these whirls for over 100 hours
without any problem. Because the ball bearing is closed
the sand from the beach can´t destroy it. Right: Drawing of the Alu whirl in GIF-format. |
