Step 1: Everything you need to know

Heres the full explanation on pdf. Here's the Flying Lizard in its service position. You can see the housing that holds the right angle drive, the sails, the caster and coupling the assembly rotates on. The driveshaft is inside the iron pipe going down to the load. This type of wind mill allows you to drive as large a generator, compressor or pump without having to hoist it up in the air.

You may need some help with this . Try for a calm day. I screwed the bootm studs to the post, then used them as a fulcrum to raise the windmill.

Step 8: The Modified Flying Lizard

Since the last edition the Flying Lizard has been changed to a five bladed rig with a welded steel hub. The shafts are fiberglass made from chimney sweeping rods. It wails in a thirty mph wind.
