Furling system for an odd-spindle-hub mill
« on: September 06, 2006, 05:22:10 PM »
I have carved a set of 5 foot blades (came out pretty nice if I do say so myself)and they will be attached to a spindle that will go thru the rear wheel hub off an old motor cycle.  So the hub remains fastened to the "base" plate and the spindle turns.  Just the opposite of the normal spindle-hub configuration.  One end of my spindle is attached to the blades, goes thru the hub and the other end is attached to the DCPM motor I plan to use.  After taking note of the furling set-up on the 10 footer from "wind - Our latest way of doing things", the rotor is set to the right side of the main shaft.  Can I replace the spindle-hub configuration with a "base" plate set-up and attach that in place of the existing spindle-hub set-up and if so, would I place it so the weight was centered, front to back and side to side, (blades and all) on the attaching piece?  Or do I need to use a different type of furling system?

I don't really follow what you are on about, the problem as I see it is that if you mount the spindle and generator in line it will get in the way of the tail when it furls with the normal set up. You could mount the tail hinge higher so that when it furled it would go over the top of the generator.


If you are intending to use a belt drive then it would make sense to balance the weight on either side of the yaw pivot but you would still need to mount the motor/spindle unit lower so the tail doesn't foul the belt.


As long as you can arrange things so it doesn't foul then the normal furling system will work perfectly well.


If you use any form of belt drive then it is the spindle offset you must consider for the furling. Balance is nice but not that significant, you loose balance as soon as the tail moves anyway.
