Step 7 Decision time

If you dont want to put magnets to your turbine until you make a bigger one, skip the explanation of magnet/coil placement. If you do want to make power with this, how many coils do you want? What materials do you want to use for vertical supports? What scraps do you have laying around for verticals or for the top plate?

The vertical supports. These are what tie the bottom bearing housing material to the top bearing housing material. The verticals are decided on a few things. If youre worried about airflow in multiple directions, is this something just to show people with a house fan demo, is this going to see high wind speeds, am I experimenting with some ideas that I might want to use in a larger turbine and so need to test some things in various wind conditions, etc.? All these effect if you can scrounge the parts or need to spend a couple bucks at the home center. I have some 3/4 dowels laying around so Ill use 4 dowel supports. I want to try mine out in some wind around here near the windy city (though its not named that for its actual wind speeds) so I need something sturdy but not to obstructive. Other options may include angle iron, other scrap wood, metal round stock, pipe with flanges for mounting, etc. Decide a length that suits your turbine. Your bottom spacing should be 1/8 or less between the magnets and the coils. The top should be spaced at least 3-4 for adjustment purposes. See the mounting procedures for more info. Do not put frame together yet. Leave top bearing housing separate for now.
