Turbine Blade Assembly

Disk Turbine Fermenter Blade Image

At this point you've carved 3 nearly identical wind turbine blades. This next section will detail how we assemble them. Following is the list of materials and hardware required to assemble the blades. Some of this is optional, certain things could be done differently. Some folks prefer to glue the blades hubs togther - this design is such that you can disassemble the blade set should you ever need to replace parts. - 1.25 galvanized wood screws, qty 60 - 5 16 - 18tpi 3 long carriage bolts, qty...

Building The Magnet Rotors The Mold

How Build Wind Alternator

The alternator requires two rotors to be built. The first step is to build a wooden mold. Each rotor will be made from 12 diameter steel disks each with 12 magnets on it. Once we've built the rotors we'll cast polyester resin around them to keep the magnets in place and prevent corrosion. In order to make a neat casting we need to build a mold out of plywood. Like many other things in these plans, there are alternative ways of doing things. Here we'll detail exactly what we've done. Some of the...

Building the magnet rotors

Hydro Rotor Templates

- 12 diameter mild steel disk, 1 4 thick, qty 2 - 1 x 2 x 1 2 N35 grade NdFeB magnets, qty 24 - cyanocrylate glue with accelerator - fiberglass cloth or mat, 2 square feet - 1 2 gallon polyester resin Start with two steel disks, 12 diameter. Each disk should have 4 1 2 holes on a 4 diameter circle(a touch larger to provide some clearance is nice) and a 2.75 hole in the center. You can build a rotating table and do a pretty neat job cutting these out with an oxy-acetaline cutting torch, but we...
