DIY: Easy to make greensand for casting metal - Aluminum sand casting



Simple step by step instructions and sources for ingredients. Your goal for good greensand is a clumping function so that it will hold it's shape easily. This is accomplished with bentonite clay powder which is the same ingredient that clumping cat litter uses. It has many industrial and health uses but you want to make sure your bentonite is a find powder. I picked up the Bentonite from http://www.foundry101.com at a reasonable price. I used about half of it to make this batch of greensand. I store my greensand in a plastic tote it a sealed lid.

The other dry ingredient is silica sand which I ended up getting from Carquest Auto Parts. It is used for sandblasting. It was not as fine as I hoped but the results were very good none the less. I have found playsand to be unacceptable coarse and don't suggest using it.

The final ingredient... the water! It came from my sink. I am using a simple hand pump pressure spray bottle to mist the water for even distribution then folding and mixing using various methods. Mixing well is absolutely critical. After I made this video I learned that covering the sand with a tarp and stomping it often during the process will help improve the quality of the final product.

The better quality the greensand the better your molds and final casting will turn out. Once I made this actual greensand my metal aluminum casting projects escalated to a whole new level. I also built a set of reasonable quality casting flasks which I will make a video about soon.

Kitty litter is clay, don't use fragrant type

Автор cfjulian1225 (4 месяца)
The sand you are using is awfully coarse for typical molding sand. You
might want to get some 2NS sand from a concrete supply or gravel pit. The
problem with gravel pit sand is that depending upon the state you are in,
it might contain a lot of limestone, which will hurt the finish. If there
is a foundry supply in the area, buy sand with an AFS grain fineness of 70
or finer. The higher the number, the finer the sand. I run a production
and prototype foundry and we use an AFS 100 grain fineness sand. We have
used AFS 400 sand in the past. When I was young, we would mix sand with an
eastern coal shovel on a concrete floor.. Just place the sand and
bentonite together and turn it over several times till it is well mixed.
We always used a garden hose with a spray nozzle to wet the sand.
Typically, you want to let the sand sit for an hour or so after you have
cut / mixed it to allow the moisture to become more uniform throughout the
sand. Mix the sand and water with a shovel. Store it in a plastic bucket
with a lit to keep it from drying out. You can cleanup the sand with a
broom when you are done. You didn't say if you bought southern or western
bentonite. Typically, if you use rounded silica sand, you will want a
mixture of 50/50 western and southern bentonite for aluminum. Western
bentonite is stronger than southern bentonite. Too much western and the
sand wants to stick together in hard lumps after you have poured your
molds. We typically run our mixture at 7.5%, not 12% clay. That is a
little high. More clay reduces the permeability of the sand, making it
more likely that if the sand is a little too wet, you will get steam
bubbles that will push through the metal as opposed to going out through
the sand. These are called blows. If the sand is wet enough, it will
rocket out of the sprue (the sprue is the hole that you pour the metal into
the mold), something fairly dangerous. The sand should stick together like
snow does, when you squeeze it. You should be able to take the squeezed
sand with two fingers, and shake it lightly without if coming apart. If it
crumbles, it is too dry. It should not stick to your hand. If it sticks
to your hand, it is too wet.

You will find that the green sand would have worked much better if you had
put the clay in a bucket with water and boiled it. This activates the
clay. Otherwise, it will only slowly become active as you pour metal into
the molds and the clay gets steamed. Over time the sand will nearly double
in strength. With this level of clay and the strength it will achieve, it
will be difficult to get a smooth casting without the sue of a fine screen
(called a riddle) to break up the lumps as you put sand in your mold. You
should use a riddle with 1/8" x 1/8" holes. You can order these from
companies such as Freeman Supply and are known as a #8 riddle. The number
is the number of wires per inch, or you can make your own with hardware
wire screen.

I would be careful if you decide to use plaster. Plaster must be very dry
before you pour it. Typically, you want to bake a plaster mold in an oven
for at lease 8 hours at 600 degrees before pouring it, to get the moisture
out. Failing to do this often results in aluminum foam as opposed to solid
aluminum parts.

Автор Larry Tischler (8 месяцев)
Many years ago we made 12 to 16 ounce "bell shaped" surf fishing weights
from Padre Island. beach sand molds. That sand is a little too spherical to
cast much detail. We were using old recycled fishing weights and it is
nearly pure lead. One or two of per cent tin added can get you better mold
fill-out. Consult the Lyman Cast Bullet Handbook available at a library.
Will you use steel clips?

Автор lilwoodboy (1 год)
I used super cheapo cat litter in my greensand. I can't say how well it
works compared to pure Bentonite, because I've never used it, but I get
good results casting aluminum. I used my Magic Bullet blender to powderfy
(new word) the cat litter and then sieved it. I used a trowel to mull it by
hand. If you smear the clay into the sand really good it will hold the
shape of your pattern much better. If someone doesn't mind doing the extra
work to save a few bucks it's a good way to go. Thumb up

Автор The Ammo Channel (1 год)
That's how I started too. Just used dirt and sifted out the rocks.
Eventually I added some motor oil as a binding agent. It worked OK. Keep it
up!

Автор motorhagel (1 год)
Grinding the cat-litter in a ordinary kitchen- blender/mixer makes it fine
as powder in a matter of seconds. This way I made about 40Kg greensand a
couple of months ago. Despite what some experts are saying, it really does
the job good. Though it required a lot of mulling before i found the
strength of the sand satisfying. Mulling in this case was done by hand..
and took me about 6 hrs of manual hard labor. Next project will be to make
a muller ;) Good Luck! and thanks for sharing =)

Автор Rod Joyner (1 год)
10 bucks at a farmer's co-op will get you fifty pounds of super fine

Автор djpaulk (1 год)
Nice vid..Sorry to burst Ur bubble,,The process you use is fine for the 1st
1/2,actually well detailed,But that silica sand is only 00 grade.So it does
not matter how fine ur bentonite clay is.The surface finish will only be as
fine/detailed as ur 00 silica sand.Bentonite clay is expensive as hell.Why
not just use fire clay?It is less than $20 for 10kg ..You will then have
change left to buy a sieve/riddle.I hope that white thing was NOT
polystyrene,the thing U put the cope/drag UPSIDE down on??

Автор Ars Armagus (2 года)
Not a problem. If you want a relatively smooth finish for castings, then I
would suggest using a thin layer of Talc on the form used to make the mold.
This also helps with the removal of the form from the mold.

I had considered the catlitter thing before doing this and decided against
it. The reason is that while yes, clumping litter does contain bentonite --
it is chunky. The bentonite I purchased was ultra fine, like flour, which
allows it to "coat" the grains of sand. I'm not sure that you could grind
cat litter that well. If you try it please let us know the results! Thank
you very much for watching and commenting.

Автор TESWiki Dawnguard (1 год)
Very cool! I'm gonna have to try this. My first mold material was just
dirt, I went outside and cut my shape into the dirt. It worked decently
well, but the dirt was too wet. I didn't have a steam explosion, luckily,
but the water content of in the dirt boiled immediately on contact with the
molten aluminum, which resulted in a lot of little air bubbles in the
surface of the cast. Overall though, for my first time it ended up pretty
good. I'll have to look into making some of this stuff though.

Автор Ars Armagus (2 года)
The finer the sand, the less it will permit water to evaporate. This will
cause explosions during casting.

Автор alsledge46 (2 года)
Very good info. Thinking about getting started doing this again. I have an
original furnace and several foundry tools built by C.W. Ammen in Manitou
Spring Colorado. He sold it to a friend of mine who gave it all to me. Now,
25 years later I'm ready to get involved again and put a fire in the
furnace. Bentonite/water green sand seen like the best way to go as
Petrobond is getting too expensive. Thanks for taking the time to show
these tips.

Nice video! All I might mention is that when we used bentonite powder in

Some sort of dust mask might be a good idea. Any fine powder is bad to

Hi, thanks for your comment. I am a home hobbiest and never claimed to be
an expert. I searched for vids on how to make greensand and only found
incomplete information. I like to document my progress and hopefully help

works fantastic. There are many ways to accomplish most tasks, yes, some
better than others. Rather than just criticizing maybe you can offer advice
to help me and other viewers improve our skills? Thanks.
