Hi Frank, I believe that indicate your nearby ham already exceeded the weight limit on his tower. You should have some extra marginal (read: safety factors) whenever you build a tower (or anything el

I have no first-hand knowledge of these towers, but I am currently working with an experienced aluminum welder (military aircraft) on a tower project. Presuming arguendo this is not a "buttering" pro

It is interesting to note that the Glen Martin aluminum towers do not use welds but instead use a bazillion fasteners. They have their own issues, but I suspect they are more amenable to a reliable s

The same issues do not manifest themselves with welding on steel towers even though they exist. The reason being the steel is strong enough and is not subject to some of the idiosyncrasies of welded

Heights Tower web site has a technical section and a tutorial on their tower designs. In the tutorial there is a table of tower section specifications related to 6061-T6 aluminum. One specification i

The lower strength of welded aluminum is recognized in the Aluminum Association Specifications standard, and the new Heights series used the lower value in the design and analysis of the tower sectio
