It looks like the wind section needs some more information and I need to get inspired to put our 800KW homemade axial flux wind turbine back in the sky again.
I went looking through my Gmail where I have morning newsletters going back to to 2005 I think to see if I had information about how Kevin and I built every bit of our wind turbine after attending a workshop in Colorado with the OtherPower guys Dan Bartman and Dan Fink.
This is image heavy by 2011 standards I hope it doesn't bog this site down.

Title: BMN wind turbine returned to sky
Good Morning and hallelujah
Note: I had text intertwined with images in my newsletter and they were posted on my now defunct site outfitnm.com. Here the images are posted as attachments. They still have the descriptive filename so I hope this is still coherent.
This windturbine is built entirely in our shop right down to the neodymium magnets and the hand-spun coils in the alternator. This is the second set of blades made on a CNC machine, at the local community college which sent us to the workshop to learn how to make axial flux wind turbines.
Kevin and I set the new Cedar wind turbine blades with a wooden disks left over from one of the last sets I guess. Anyway, I found them in the shop and we employed them just as quick, which helped get the blade set together quicker.
Kevin designed this new shape and he is the CNC instructor at the college so he cut them from the blanks I made from Western Red Cedar.
I love the shape but will it harvest enough energy from the wind to spin our new alternator to its full potential?
This set is replacing a six inch blade length smaller set. It will be a tough act to follow Wind Swept Area formula for blade length is: 5 feet = 1.524 m swept area = pi * r2 = 1.8241m2
Kevin balancing the blades. The key in our case where we have a poorly constructed magnet rotor is balancing the blades in place. This image is from Saturday,we pulled the turbine down again twice on Sunday and added more lead weights to two of the blades because there was a severe wobble
Brian getting ready to use the breaker bar to really tighten the bolts on the blades.
Thank goodness the shop is close, we had to run for tools while the other guy waited, I can't count how many times.
The turbine seems to be working well. We only had 5 to 10 mile per hour winds to check it out.
Here the turbine is rising via energy over the gin pole connected to the red Blazer, which has conveniently placed hooks in the front bumper

Kevin holds back on a rope connected to the top of the turbine so that when it reaches the top of the pivot it sets gently down.
Our tower is easy to work. Sunday I made a new cable going from the vehicle to the gin pole so that the vehicle is out of the fall zone.
All we need to do to secure the tower in the upright position is bolt a plate of heavy steel on the gin pole
Yippie she flies
I have more information on this design and various builds. Feel free to ask questions
I was over at my Youtube channel looking for videos of our aquaponics system and remembered I had a few videos of the axial flux windturbine project and thought you might like to see what it looks like.
Raising and lowering was a two man job while I had help, not long afterward I learned to raise and lower the tower by myself using whatever 4X4 I had at the time.
It's all about balance and trusting the rigging, which helped me in my new career as a rural - mountain Wireless Internet installer climbing up 100 foot towers. Test your rigging and then trust it.
I feel better now that I don't need to worry about people that help me being in the fall zone.
I still don't understand all I know about this.
Why does your bag say "bombs"? The reason I ask is that my bag says "tiny ads" and it has stuff like this:
