Things for this project were not going well and it was abandoned to work on more important project. At least, more important to me. My POVFan has not been forgotten and could be revisited in the future. I still want to get it working, but it seems that some compromises will need to be made on the design if it is ever going to become a viable prototype.
Enough background
----------
Embellishments were removed from the drawing and a 1/4" (6mm) hole was added for the time being. This way, they could be connected and hinged together. Around the hinge hole was a groove which would be large enough for a pop rivet which would keep the fan blades from opening up too far by providing a track.
Four blades were cut without the time-consuming embellishments to test the feasibility of the hinge and pop rivet grooves. The size of the grooves was wide enough, and the bolt sufficed as a stand-in hinge, but the grooves were cut incorrectly, so the blades were not able to move properly.
