wire guide for tower

I will be putting up a windmill and i need to know if a 2 inch pipe for a 60 foot tower is sufficient?  I also would like to know if anyone knows what distance the guide wires should be from the tower? is there a rule of thumb about the lenght of the tower and the distance and angle of the wires?  I searched through the forum because i remembered seeing something about this a while ago but i can't for the life of me find it. p.s. the windmill is a 3 phase AC motor conversion - it's not finished but it will be at the end of the summer. (wishful thinking) thanks! Frank

I have found this usefull. http://www.bergey.com/Products/XL1.Tilt.IM.2.pdf This is not about wind turbines but may help... http://www.jea.com/about/pub/downloads/contractor/OH-2-Guying.pdf Also 2" pipe is not realy adequate for anything other than a small unit. Idealy large diamiter say 3.5-4" but thin walled. I have a 60' tower made of 2x2" and top 20' of 1.5". Bit scarey to raise and strictly for testing small units, ie TDM's. Anchor points at least a radius of 1/2 tower height, preferably 2/3. Type and size of anchor depends on your ground. The further away from the tower the anchor point is the less stress on each anchor, but more cable. In my experience an anchor radius that aproximates gin pole length simplifies raising. Never undersize your cables which should be at 20' intervals or less. Top anchor as close to the top as possible without the blades hitting it. And i'm sure there is more but someone will add to this. allan down under "Dream as if you'll live forever, live as if you'll die today." James Dean
