While I suspect there is no confusion in the ongoing current banter about
the Tri-Ex W-51, it might be well to remind all that the W-51, as I
recollect, differs structurally from the later WT-51 (one of the crankups I
have). I don't have the specs for the W-51 but was there not a difference
in the wall thickness of the vertical section tubing, the W-51 being
thinner, thus reducing the load the tower could handle?? Seeing so many of
these being up for sale or in use it might be useful if someone could post a
chart that differentiates the important differences between the two,
including whether the base mount dimensions also differ. This would be a
useful tool when looking a load capability.

Sir, as respectfully as I can....
IF you are going to ignore our repeated and unanimous? recommendations,
then please do us the courtesy of NOT lecturing us about it.
Or at least write the lecture better and in a format we can slog through
in order to spot your glaring engineering/fab procedure mistakes (if
any... there always are, even with professional engineers).
Sincerely,

Unfortinately their online and openly published documentation in my
opinion quite vaugue and incomplete with respect to designing and
fabricating your own base. I would make a guess that a decent amount of
marketabilty for them comes from design services. They will sell a
service and paper packaged presentation with engineering wet stamp of
your older second hand tower revised with reccomendations and recaculated
to new standards. They also have a more basic set of generic instructions
that they will ship with new base purchase.
The base with suggested installation instructions with example for areas
with adobe type soil conditions are similiar is included for $395 plus
$200 shipping.
This might be very necessary if you require inspection. I am headed right
near there this weekend and considered just paying the $400 and picking
it up in person. However,, they dont carry these pieces in stock and
there is a whole proccess of placing the order and the sales staff places
the build ticket with the production dept. and a notice to notify the
proper design staff who orders the material and sends it to fab who
builds it in the order recieved. After its finished it has to be sent off
for galvinizing. In other words it wont be ready ...... ready for several
weeks up to couple months and certainly not this same weekend I am
traveling thru there. So now we are looking at $600 to have it shipped! I
am so impatient i would have been compulsed to pay $400 with the mindset
that I am getting some limited factory support for a twenty something old
tower. (the fact that they support old tower that predates their interest
in the TriEx company is really worth a premium) A
s
I
mentioned before I am impatient and I also draw the line at $600 to have
to wait up to ? Months?
Their written review service without any design considerations of your
old tower cost $200
If I was for sure going to be inspected I would buy that....
As far as detailed erection instructions it appears they are going to
need to be reimbursed.
Man! Go look at all the design details and information that US TOWERS
makes avail on their site..... So much for proprietary information. I am
acquiring my rebar and doing concrete work as per US Tower info.... still
no fabrication of actual base stubs. I did acquire 3/8 steel plate
tho...... that appears to match that of the tower legs.
Should I be bumping that up to.1/2 instead?
I agree that 3/4" holes perfectly lined up in 1/2" steal isnt something
that you are going to do with a step bit and a cordless dewalt.
It is my similar thought that these holes would likely be a job for
Bridgeport or similiar milling machine.
As for the steel alloy? Anyone offer up a clue? Also need the size and
type of rebar that is used to weld onto the tabs?
That no weld method sounds like kinda iffy with using angle? I Do notice
that US Tower does similiar with anchor bolts. I just rather see more
metal from the legs going into the concrete below than welded to a top
plate. I saw one where the guy welded gussets . That seemed a bit better.
US Tower definately does alot of rebar work to keep those anchor bolts
from pulling out. I Am building my cage similiar with 2#6 per corner and
the 20 #3 ties
