> Does anyone know where I can get this grout?
Your typical hardware store may not have it. I've always gotten it
from a masonry supply store.
> Do I need to loosen the bolts on the braces on the sections
already assembled to allow a crane to stack the tower or not?
Probably not. It's mostly when you assemble a section on the ground
that you might want some looseness in order to insure you can get the
sections to line up.
> How does one plumb a tower with these large sections?
Easy. You use the base bolts as leveling nuts. Since it's a tapered
tower, you should use your level on the side of the leg to get it plumb.
That's the easy way. More time consuming is using a transit. For a
self-supporting tower, you're allowed to be out of plumb something like 4" in
100'.
> I am wondering about how to install the antennas also. I am planning
to put
up a ~35 ft boom with 3 elements on 30 and either 3 or 4 elements on 40
(haven?t made that decision yet) and a large tribander above it also on a
32
ft boom. It would seem to me the best way might be to put the rotator on
the
plate and attach the mast with the top section. But then the antenna stack
install appears to be much more difficult because I have to remove the
rotator at the top, figure out a way to lower the mast to install the top
antenna, push the mast back up, and then install the bottom antenna (and I
am sure I probably skipped a whole bunch of steps even more difficult).
Since you have the crane there, you use it to first lift up the mast
and then each antenna starting with the bottom antenna of the stack.
Otherwise you can use the tram method which takes more time, hardware and
knowledge. I'll use the crane every time. If you try to stack the top section
with
the mast already on it, you won't be able to get the section to hang
vertically plumb which'll cause problems when you try to attach the section.
This
is one of those things that'll bite you in the butt. Break everything down
into one bite instead of trying to do 2 or more things at once.
> The other way might be to mount the antennas to the mast sitting on the
ground,
(if I can find a way to stand the mast up) and then have the crane lift the
entire assembly and drop it through the tower top and thrust bearings.
A very difficult proposition. NOT recommended. Many butt bites in this
scenario.
