[TowerTalk] Driving Screw Anchors

Has anyone used a post hole auger on a tractor to drive screw anchors??
I think they are a bit too fast, but might handle the job if properly
managed.
I'd rig a telescoping shaft, like on the pto driveshaft, to go between the
auger drive coupling and the anchor eye.

Thanks for the quick reply & as I thought, there has to be a mechanical
"advantage" employed!!! Hence the 4' pipe.
Thanks again.

Tom,
I can't say this is the right way but it worked for me. Flip through the
pictures and you will find how we simply banged on the anchor and turned it
a much as we could. A new hit and you could turn it again. It took about
half an hour to install one.

Having never installed one, how does one install one by hand? Dumb
question but I'm faced with maybe doing it & need to be an "inquiring" mind.
Thanks for your input.

It
is not that hard to install a new one.

This question somewhat oversimplifies the decision.
First of all, I have a MonstIR on a tilt plate. Thus
all antenna work is done with the tower tilted over,
never in the upright position. The tower has been
up and down many times to:
1. Debug the MonstIR when initially installed.
Dozens of times up and down. I will say that
once I got the MonstIR working, it has never
failed...yet.
2. Develop the homebrew tilt plate by trial and error,
now you can just buy one.
3. Fix the antenna to keep it from slipping on the mast
4. Diagnose and treat an insidious intermittent coax
connector on RG-218. Multiple times.
5. Fix an element that fell off (my bad, I forgot to
tighten the clamps).
6. Develop a modification to the MonstIR to use the
reflector and 2nd director as an 80 meter receiving beam.
A lot of trial and error here.
7. Periodic inspection and maintenance several times a
year for cable lubing etc. Replace cables "every 3
years" (right).
8. Make an emergency repair right before a contest
(Murphy's timing was impeccable).
9. Perform experiments like putting up a 130 foot
high 80 meter inverted vee.
Having said that, the supplied K2550 winch was
undercapacity for even the empty tower, not to mention
the MonstIR on top. The brake severely overheated
and I never trusted it. A replacement W3000 winch
had different but equally bad problems. I never trusted
it either. Either winch was like an athletic event
to turn using both hands. To me, the answer to how
many times a year is OK to hand winch the tower over
became zero.

Perhaps you need to read the BOTTOM of the emails from this reflector.
Full instructions are ALWAYS there.

Tom,
I used 6' Chance screw anchors to install my 76' stick of Rohn 45G four
years ago. Soil here is about 1' of topsoil, clay underneath.
I dug through the topsoil and used a square steel bar about 6' long that
just fit through the opening on the Chance anchor and used the armstrong
method to grind them down through the clay to about 6" above ground. Lots
of sweat equity, but it only took about a half hour per anchor.
I have a 4L SteppIR at 77' and a 2L 40M Moxon at 95' and the anchors have
never budged.
Best regards,
Paul W0AD

It is not a dumb question If you have soft soil with no rocks your should
be able to start the screw on an angle and use a lever to twist it in. I am
not sure what you would do by hand if you have hard clay, shale and rocks
like I have. Generally speaking the easier it is to screw in the easier it
will pull out. Machines that install them measure the installation torque
to ensure adequate holding ability.

Hi Tom,
20 years ago, I did mine by hand, using a pipe. On the new tower I found
that I could no longer do that by myself. 6 years ago I rented one of the
power augers from home depot. I got the trailer mounted unit You can rent
them for cheap. I used the augers that came with it to drill 4 holes close
together and then Shoveled them out. Take off the auger and Use the Kelly
bar to drive the anchors. Towed the trailer to the house and walked the
auger to the back yard. It took about 30 seconds to drive them in. I was
able to drive the anchors In less time than it took to line up the auger
trailer. We also drove 3 more For N4BAA and had the unit back to home depot
in less than 4 hours.
