[TowerTalk] Tri-Ex HS 588

[charles mcneil]

    I am building a wind generator and have bought a Tri-Ex HS 588 tower from a neighbor. This was evidently a three section 58' crank-up tower but the top section was missing. 
    I want to weld in some support plates in the top and install a 12' piece of schedule 40 pipe to set my generator on. the generator will weigh about 250 lbs with blades.
    The local building inspector tells me I will have to have an engineering report saying the tower can be used for the purpose. I plan to guy the tower at 20' and again at about 40' but have no idea how guying a self supporting tower affects it's wind load capacity.
    Does anyone have any specs on this tower? Anyone have any suggestions on how to deal with this problem? I have looked into new towers but quickly found out that I would have more money in the tower than I could ever get out of Renewable Energy.
    Thanks for your thoughts and time, CHUCK
