I just watched on www.youtube.com how to make home made plastic and it
works..
look up home made polymer on youtube... there are several videos on
it.

basicly you take a glass jar and put some ascetone in it.. then you
put chunks of styrofom in it until no more will disolve... then you
can pour this slurrey into/over a mold and make a part or you can wait
up to about 5 minutes and it will be like clay and it is moldable. the
more of the ascetone that evaporates the harder it gets.... if it
starts setting up too fast, you can add more ascetone.

possible ideas for this in the tank field:
track molding
tank bodies
custom motor mounts
details and acessories
and more!!!!!!

Cheap and easy!!!!!!!

I saw a similar video actually tried this method once, or rather a
variation uning gasoline instead of acetone, and wasn't really blown
away by the results. I could not believe how much styrofoam it takes
to produce a few ounces of slurry. It would only be really practical
for small parts I think, and you won't get much detail without a
vacuum system. Also the last part of the drying process took a
rediculously long time (Weeks!)and needs to be performed outside,
Although this may be different with acetone. I HATE spending money,
if I think I can make something myself, but i'd go with smoothcast if
you can get it near where you live...unless you really like fumes...

you had poor results because of the gasoline... it is petrolium based
and will not give consistant results. try it again with ascetone. But
yes it will take alot of styrofoam but it is cheap in or in most
cases, free.....

there is also one other meathod you can do using 1 gallon of hot milk
and 3 tablespoons of vinigar. It makes similar results after you
strain it.

I hear there was once an aircraft carrier made of ice...but a tank
made of cheese?

I've heard of that aircraft carrier too, wasn't it a frozen slurry made out of sawdust and water?
Anyway, this stuff sounds like napalm, that may be because that's exactly what this is.
Making organic plastic is actually a rather good way of making it yourself, as most people don't have the equipment to make petroleum based polymers.

I didn't know polymer was petrolium based... hmmm... but I did try
this and it worked... I poured a small 5" x 5" slab 1/4 in thick and
it was strong... I tried to break it but it would only bend with lots
of force. I guess it depends on temp and styrofoam used, I don't
know... science and art to it I guess.. I might have just got lucky my
first time
