When I have seen the rextorn video, I decide to make my own copper dragon egg!
I make no photos of the egg construction :(, but the proccess is exatly the same as the rextorn video.
I will do photos for my next copper egg.
At the end and after 60 hours of work, the copper egg weighs 2,7 kg for 23 cm.
What you will need :
- Styrofoam egg 20 cm like this
- 4 copper plates 20cm*40cm*0.5 mm
- Gas torch like this
- Sheet metal hand like this
- Metal polish like this
- Cement bag
- One plastic container 40cm*30cm*30cm
Step 1: Do the Egg Print
With the cement, one container, and half of the styrofoam egg do the egg print.
But the cement and some water in the container.
Wait 3-4 min and use the styrofoamto make the egg print.
Wait 10-12 hours after.
Step 2: Make the Copper Egg
Unfortunatly I take no photo of this...But it is not so difficult.
You will have to anneal the cooper.
You will find a lot of video on internet like this
Use the gas torch to heat copper and when it is red, put it quickly in water. Then you can use a hammer and the cement egg print to shape the egg.
You will have to repeat the process (anneal + hammer) a lot of time to get and half of copper egg.
When you have one half, let's go to make the other half.
When you have the two half, you can soldering them with some tin.
Weldone, You have make the most difficult!
Step 3: Make the Scale
Now the proccess is exactly the same than Rextorn video
Before doing this, I make an example with the styrofoam and some paper.
I use 3 cuts of scale :
- 2cm*2cm => red paper
- 3cm*3cm => purpple paper
- 4cm*4cm => green paper
Use the sheet metal hand to cut the copper.
Use the hammer and the cement egg print to give some curve to the scale. Be carreful use some small piece of fabric because you don't want scratch the scale :)
Use the hand sander to make some curve on the scale.
Step 4: Soldering the Scale on the Copper Egg
The proccess is exactly the same than Rextorn video
I use then gas torch to do the soldering.
I begin with the 2*2 sacle, then some 3*3, then all the 4*4, and then the rest of 3*3 scale.
My attempt with the styrofoam and some paper was very hepfull....
Step 5: Finish the Copper Egg!
Before finish the egg, make a lot of example. You really doesn't want make a big mistake!!!!
For the black patina read this thread (in french).
1 => Use white vinegar too clean the egg.
2 => Use the black patina (I recommend to make a test before!!!!)
3 => Polish with the hand sander (Test the polish before used it on the egg)
4 => Use the metal polish (Again make a test before)
Step 6: Find a Beautiful Box
To do :)
