Okay, since you posted this to the whole reflector here you go.
I've worked on over 175 amateur stations and have encountered many
'amateur' shortcuts and outright WRONG things in a myriad of tower/antenna
installations. While many times the owner gets away with it (after all,
everytime you speed you don't get a speeding ticket, do you?) and then other
amateurs think that's the correct way to do something. In fact, I wrote up my
"The 10 Most Common Tower Building Mistakes" years ago after seeing the same
mistakes/problems over and over again. It's available at <A

I'm not here to discourage homebrewing things but I draw the line at
antenna support structures. In order to do a credible and reliable job of
homebrewing an antenna support structure, you need to be conversant with
materials, engineering, fabrication, welding and installation in your above
example. The vast majority of amateurs ARE NOT CAPABLE of doing this in any
way, shape, or form. Look at the kind of questions that are asked here on TT
by people who have good intentions but don't have a clue about wind forces,
soil types, guy wire materials, etc. TT exists to help keep them out of
trouble in their progression from 'know nothing' (Hey - we all started
there!) to knowledgeable tower owner.
Rohn 25G wasn't widely available in 1963 but these days it is and you can
get used sections for a relative song so you don't have to spend a fortune on
a tower. I just don't see the need to re-invent the wheel when it's
relatively inexpensive and already well engineered.
They used to publish tower designs made out of wood too. Don't get me
started on that one.
I'm just against 'back-of-the-envelope' engineering by people who aren't
qualified to do it. I don't want people to learn their tower lessons the
'hard way' - it can be detrimental to your on-the-air activities.
