At KidWind we get lots of questions about quick and fast ways to attach wind turbine blades to our wind turbine hubs. Here is a modification I invented that eliminates the use of hot glue, so that students can test and try their blades at any angle and with any medium, and can quickly remove or "un-clip" blades to make adjustments.
We have found many uses for the cliphub. It's very useful in a walk-up blade making situation. Or for classrooms that have one KidWind turbine and one hub, but many students who want to test their blades.
Simply have your students make their blades (do not have them hot glue the dowel rods on the blades), then have them clip their blades the clip hub that's mounted on the turbine. No need to remove the hub! No need to unscrew the hub to adjust the dowels! Just clip on the blade material, adjust the pitch of the blade by holding onto the clips and turning, and you're set to go!
