Well, I’m hurting, this project, while we think was totally worth it, took all damn day.
Such a fun project, this rebuilding of our wind-turbine and tower-top delivery system for lights, and later flags banners or whatever.
Rebuilding the turbine took more time than I thought it would, or perhaps I just didn’t think about how long it was going to require. Sometimes not thinking about the time commitment is part of the motivation. Still I made it happen in one day. I love one day projects.
One of the issues which slowed me down was the bolts which hold the wooden blades together as a set were too long. When I tightened to big nuts holding the blade-set to the axial flux permanent magnet alternator the smaller bolts hit and distorted the magnet rotors causing the turbine to not spin properly. I had as usual pounded the blade-set onto the hub of the turbine with a small sledge hammer and I didn’t want to pry it back off to remove and shorten the smaller bolts.
My idea was to remove the nuts behind the blades and pry the bolts in question out one at a time then grind them down fix their threads so the nuts would go back on in the extremely cramped space. As soon as each nut came free it and its washers immediately flew off and stuck to the magnet rotor. This was fine with me at least I knew where they were. The tricky part was going to be threading the nuts back on with the powerful magnets fighting every attempt.
Three tools in two hands, plus the nuts and two washers. I’m pretty dexterous and managed to accomplish the task with fair amount of dignity and grace. If it wasn’t for this newsletter no one would ever know of the feat performed that cool December axday in order to make a crazy idea of stringing twinkle lights up nearly the top of our fifty foot tall wind turbine tower.
Still I wish the wind would blow a little so I can see if the damn thing spins. I also balanced the blades. This means adding weights to which ever blade ends up on top after a gentle spin, and of course the wind was blowing then. Even though we had an inconvenient breeze it was obvious which blade needed lead weight, there were screw holes in the blade that kept returning to the top position.
All right, it is Friday!
Let’s get this day in the bag and get on to the weekend.
I’ve got an inkling of what I’ll be working on today, not certain though, but I believe I’ll be returning to Ride to Pride to upgrade their WiFi to the newest MIMO (multiple in, multiple out) WiFi. They should have a wind turbine as the wind is a constant out there by the airport.
