Step 12: The Stand.
The stand for my VAWT was made from lengths of old lorry chassis that was in the scrap heap. I was working with what was at hand so i will not give dimensions other than its about 1mtr tall and the base is centered around the axis or the bearings.
The upright beam is 3" x 1" x 6mm channel iron again from scrap.
The cups for holding the bearings are just cuttings of pipe that the bearing where a nice fit for and are welded to the frame.
The stand cost approx £35 to build 2 years ago, this was due to the cost of bearings and a 1mtr length of 25mm rolled steel bar at a time that steel prices where very high.
There is a taper roller bearing mounted in the top cup and a standard roller bearing in the bottom.
The frame was buffed free of flaking rust using a flap disk in an angle grinder and painted with 2 coats of a rust killing primer and then 2 coats of agricultural oxide.
It may not be pretty but it does the job.
