Nice toy. I have one for mixing pyrotechic compositions, but it's nigh-on
to useless for any concrete job. Seven gallons is just a shade less than a
cubic foot of mud, and you can't fill the OddJob mixer full, or it doesn't
You can mix concrete with a hoe or shovel in a bath tub, or other
receptacle. People did it for years and are still doing it. Use your
shovel as a measuring device and shovel in the required shovel full's
of cement, sand and gravel and add a little water and start mixing.
Strive for the least water you can use to get a mix that is as strong

I've mixed many a yard (or meter) of concrete in a wheel barrow for
jobs that didn't warrant getting the 3 point hitch mixer mounted on
the tractor, as well as for jobs after I left the farm.t's good
Just go to Harbor Freight and buy a cheap mixer. When done, scrap the
metal and keep the motor. Some of those last if kept painted on the
55 gallon drum of concrete - 1/2 rock and 1/2 sand and cement is to
heavy to move about. Most people can't handle a wheelbarrow.
Consider if not a cheap mixer, then a 1/2 bag roll-a-round plastic
bottle that has fins in side...

Mix it in the wheelbarrow. Use a rake or hoe.
There are, I think, flexible plastic 'barrels' which are meant to
be used to mix small batches of concrete in places where a powered
mixer is not an option.

Is it possible to mix say 1/4 a yard of concrete that way at a time? Maybe
using a 4x8 plywood sheet and 2x6's for the sides making a box to mix every
A plywood sheet with 2 x 4s to frame it is a very common kind of
homemade mortar box. The last couple of jobs I did used that setup,
with a shee of plywood that was 4 feet square.
Whatever you use, get it down low enough that you can work it with a
hoe and/or shovel (I use both, alternately) without reaching up to get
at the mix.
I hoe the ingredients together; flip the pile over with a shovel; and
then hoe again. Once everything is mixed dry, further hoeing will only
tend to separate it.
I add water slowly, working it with both hoe and shovel, making sure
it's absorbed all of the water before adding more. When it's 100%
mixed, with no dry cement or aggregate visible, you're done. Adding
more water at this point with only make for weak concrete.
And it is a lot easier to do it in a 4X4 square 6 inches deep than a
4X8 3 inches deep. In the big steel wheelbarrow I think we did pretty
close to 1/4 yard when we were mixing "in situ" where we didn't need
to wheel it too far.
1 big bag (94 lb - 1 cu ft) in a 1-2-3 mix makes just under 1/4 yard
(6 cu ft) of concrete and we did 1 bag batches.
7 cubic feet is a lot of concrete to hand mix in one batch and get it
consistent. And you would have about 3 inches of concrete in a tray
that big with all the moisture being sucked out by the plywood.

standard strength is about 3300 lbs per yard - so about 820 lbs. But
yes - it IS a pretty good sized batch - about 8 feet of 40" sidewalk
3" thick - or about 6 feet of gutter in the dairy barn when we were
putting in the stable cleaner.
We used the mixer for that job - and I shovelled all the gravel twice
- once out of the pit into the trailer, and once into the mixer. The
next summer it was the hog stable floor and about 1500 square feet of
manure yard. The summer I turned 14 I knocked out all the box stalls
with a sledge hammer and the gutters in the dairy stable, then mixed
the concrete and filled the cribbing the boss hab built.
The next summer it was the manure yard and the hog stable floor, and
replacing half a dozen or more beams under the hay-loft - over the
stable (big old bank barn - about 100 years old) with 12" square
elm-about 14 feet long IIRC. (Dutch elm disease was killing all the
big elms in the woodlot - and we had some BIG ones) Winter weekends
were spent cutting the limbwood with the 40" circular saw belted to
the old 44 Massey and splitting it with an axe. Gotta be well below
freezing to split rock elm or the axe either bounces or sticks.!!!
