Scratch Build – In Progress C&C tiberium wars Advanced flame tank

This is getting better and better.
Loved the Temple of mod shots too.

 

Looks fun, definitely want to see how this ends up

 

Lots of info there :

Nuh-uh! Pardon me if I camp out here for awhile.

 

nice site!

 

Holy maoly macaroni

 

I sure hope you plan to video all the trial runs and final runs of that casting.. I'd so watch it even if they were hours and hours long.

 

Welcome to BT!


This looks like it's going to be awesome, based on your plans so far, and the work you did with the previous mod. I admire and appreciate the machinist skills, and look forward to learning more about foundry work!

Update 3 - refining aluminium and first sandcast pour

I wanted to refine my aluminium first to obtain a reasonable quality by mixing good quality together with scrap aluminium.

This is the setup of the system, 6 bricks are used to keep the funace extremely stable.
and 3 heat resistant bricks are used to set the crucible on.


The torch is now on, the best thing is my IR -thermometer indicates the outside wall doesn't get very hot, this insulation is doing its work.


You can see the hot flames rushing out of the pot, things are getting hot now!.


I don't know what this black stond exactly is, at the shop I was told it is used to clear the aluminium of any oxide.
When sturred through the aluminium mixture the inpurities will start floating at the top.
This should be scooped off , till you see nice shiny liquid aluminium.


Now I am wrapping the cleaning agent in the aluminum foil so it can be dropped in the crucible.


When working with liquid aluminium: DON'T forget to use you anti brain scanner hat.


Next I mix and stir the liquid aluminium a bit so the impurities start floating.


Then the impurities can be scooped from the liquid.


Then the aluminium can be cast into forms I use : "mom's patented cake cups "
The aluminium starts out shiny but a dull film starts to develop very fast while it cools.


a nice video of the whole proces.

You can see the crucible is kind of hot.


After some pours we have nice refined nuggets which can be used later...


sand casting and first pour

I want to make sandcasts and thus I needed some tools to create these casts.

I started by creating some casting molds made from plywood, the casting molds excist out of 2 parts which can be lifted from each other to remove the molded object(s).

The mold is marked so you wont make a mistake, how it is put on.


Next up were 2 small (conical) wooden objects which are easely to remove from the cast.
one is the pour and the other is used as riser.


Now it is time for the first cast, this gear will be casted and will now function als the mold.


I dispense some graphite on the mold so it can be removed easely from the sandcast.


I use this red (oil containing) sand the create the sand mold.


Next the sand needs to be hammered onto the mold till is it rock solid and no more bubbles exist.


This is now rock solid but the rest has to be filled to prevent the sand from falling out when ramming the other side.


The excess had to be removed to leave a flat surface.


like this...


Next the mold needs to be flipped over.


next the top has to be filled, you can see why the riser and pour are used... they are sitting cold on the gear here...

After ramming the other side the casting can be removed again ... now the remove the mold itself.


You can see the riser and pour on this photo.
They will be removed before the pour...


Heating up the furnace...


This is the tricky bit.. removing the mold itself... it can be a bit sticking to the sand....


Now both parts are put back on each other... the can see the graphite and some shape of the gear...


The aluminium is hot now ... so lets get ready....

I have made a movie of another pour... but is it very explanitory...



You can see the sand smoking...


The gear can be seen now.


The black sand has been burned and cannot be used anymore ,,, the rest is still good.

You can see the result here... not quite as sharp as the original ... but you can make out they belong to each other

 

Never seen anyone sandcast with a mod before

im not too familiar with sand casting

so your riser and pour was made from wood? so does that just burn away when you pour the molten aluminium in or what? i always thought it was all like a foam...

Intresting stuff i must say i'll be watching

 

This is the first time I see somebody meelting alluminium in his garage and now I want to see more!The two gear are nearly identical.

 

The wooden riser and pour are removed before casting .... they won't even get hot
That is why they are conical, so they can be removed from the sand relatively easily

Foam is another option , you can use it when you can't remove the object because of the shape. then you create a foam piece which you will burn away.

But naturally, every time you need a new piece of foam....

 

Oooooooooo that makes more sense

Good work im liking how this is starting

 

this will be a very cool log!

veel succes, ik hoop dat je goede sponsors kunt vinden.

 

Its like being back at school again, havent seen a sandcasting session done in over a decade. Nice work so far dude & good luck with the mod.

 

Thanks man, I won't do this project with sponsors.
First because it saves me a lot of time and second because the last sponsor of my C&C temple of nod provided my airbrush and had his name placed on the mod (large).
This degraded the mod....

This time I will do the airbrush myself.

 

pass the dutchie on the left hand side

This is looking very good.
Never seen sand casting been done outside an workshop.

definitely subbed!!

wel, ik stuur mijn tuinkabouter met een grote zak respect onze noordgrens over, richting vinkeveen!

pretty crazy going all the way melting alu for your mod. but i guess that's part of the fun, right?

For me it is all about learning new techniques.
