Hello,
I've been reading the post concerning making concrete fence post's.
I am looking to do the same, and found that the british have been doing
this for quite awhile. I've got a book (a pamphlet really) showing
how to do this, and re-bar is required. Ussually 4 pieces set in about
1" from each corner.
So, yes you'll probably need re-bar, make a simple wood jig and
weld the cages up, including the nut at the top for the lifting eye.
some ramblings.
1. if you put a nut up top for a lifting eye, it will later rust
and stream down the sides. If you use stainless, it won't
rust, but in northern climates, the water will freeze and break
out the top. You could go to pennsylvaniainsert.com and
buy something pre-made.
Or,...you could get fancy, make a little mold say 9" x 9" sq.
as a top cap to set on top of the post (with a depression
for the post to sit up into) that will be a "roof" and end the
water problems.
2. Think of adding some of those commercial inserts on the side
of the post (front of post) to enable you to add a sign
"no trespassing" or such, just by screwing in a 3/8 bolt
into the existing molded in insert.
Adding a couple down the back could be for the electric
fence insulators.
3. White post's....you can get white portland, me I want to
try dark (very dark) brown, to look like the park service
signs.
4. The gizmo plans mixer...it's called a "volumetric mixer"
and I am ready to order the plans... but I e-mailed them
stating that I want the CAD file, I don't need paper.
Have not heard back yet, my idea is to take the file
and have my friends burn out the parts with their
cnc plasma table directly.
5. That gizmoplans mixer is ideal as you can mount it on
a running gear, and substituting hydraulic motors,
run it off your tractor. This you could take out to the
job site and pour directly into your forms.
6. Look at this patent: 4,922,463 at uspto.gov
assigned to the Del zotto company based in deluth, mn.
Looks allot like the gizmoplans unit based where?
7. I had someone pour 21 yards of concrete (23' x 40' slab)
and the second truck added too much water on the jobsite
(arrogant operator would not follow the finishers instructions)
there went 8 yards righ down the tubes.
If I had one of those volumetric mixers, this would never
had happened, they adjust the water "on the fly" and the most
in the "screw mixer" is one wheelbarrow load.
8. Look at http://www.vmmb.org/ for different manufacturers
of these things.
tnx

I don't work for any one listed, I ain't selling anything
just my thoughts.
