Shown is the simple way I have "turned" my nose cones from rigid 2" foam sheet as well as my new hub assembly for my 18' rebuild. I router a plywood disk and then layers of rigid foam disks are glued on top. A lag bolt is then screwed into the center of the plywood and the head then cut off making a shaft to be chucked in the drill press. Slow speed and a good wood rasp makes short work of roughing to shape. This now gets fiberglass cloth wetted out and then a few coats of epoxy sanded down to a smooth finish chucked right back into the drill press.
The 1/4" steel hub plates were plasma cut by Dave Moller to my design which I have drilled and are just waiting on the new 9' Ash blades that Dave will be carving also.
So far we have : Cast a new stator, lessened the furling angle, beefed up the high and low stops, replaced and greased new hub bearings and seal, modified the manual brake and cable guide, fabricated a new hub design and nose cone. New blades are in the works by Dave Moller and these will be reversed pitch from the originals turning counter clockwise looking at the nose cone front.
When the weather breaks I'll be installing a panel at the tower base for a "shorting plug and disconnect for untwisting the power cable" and hopefully a high speed shut down circuit. More updates to follow as we near assembly and the re-raising. Dave B.
