Maybe the majority would have to lug lots of heavy gear but I have a plasma
cutter, 180 amp Mig, AC/DC stick welder, grinder, vise, O-A bottles,
Argon-CO2 bottle, 14 inch cutoff saw, and on and on and on all on my single
axle welding trailer which is not hard to hitch up and get close to just
about anywhere on the ranch including antenna farm endeavors. I don't think
I am unique.
Point 2: wire tied cages of rebar are not nearly as robust as welded. It
is darned inconvenient to have rebar messed up under the forces involved in
pouring concrete. Dimensional tolerances are much easier to maintain with
weldments. Wire tied rebar is a very good thing with flat work like slabs,
aprons, patios, sidewalks, and the like but more 3 dimensional work is
sometimes approached easier and with more confidence with at least some
welding. Must you weld? NO, but if you can it is sometimes better for any
of several reasons.

Re: Tack welding rebar
With all the discussions of how to put up antennas and towers EASIER, I
can't get over how many of you are so dead set on hauling out all that
heavy, expensive and hard to use equipment to weld the rebar. Also someone
mentioned the unknown content of the melt (which I mentioned initially) he
mentioned bed frames. I don't know if any of you have tried to make anything
out of bed frames but when you drill it, some holes are easy to drill and
others dull your drill bits very quickly. Whenever I have to put a hole in
it, I use a carbide milling cutter in my Bridgeport milling machine !
Bottom line, go the easy route and get some rebar wire ties and twist the
stuff together. Save time and effort.
