After each pour was done (we did three pours that day), we’d have to let the aluminum cool for at least 10-15 minutes before breaking them out of the moulds.
Cooling pictures:
I’ll start with the dome. I was worried about this casting. Making the dome took the most effort and will probably need the most work after a casting. It was important to me that these parts came out as good as possible. Here are the results:
These parts were still extremely hot but very solid. Fortunately, I had the foresight to invest these parts. When the aluminum went outside of the mould, it settled ON TOP of the investment layer. This means that I can remove the extra aluminum and still retain the shape of the intended part (see the last picture).
The dome halves still retained that white foam texture but I think I can smooth things out with Bondo.
Next we cracked into the small coils:
Sorry, all of the medium coil pictures ended up being blurry. I was just so excited at the results.
Here are the small and medium coils together:
The large coil picture was nice and clear.
And now for the disappointment… Every project has its failures. The first attempt at the leg was one of these ‘learning lessons’. When we went to pour for the third time, apparently we ran the furnace too hot for too long. Melt, just like your food, can be over cooked. Over cooking your metal causes funny reactions with other substances, faster oxidation and can cause weird pressure issues inside of the mould. Without being able to see into the mould while we’re pouring I can only assume all of those things happened. You could see the disappointment in my sullen poking of the aluminum corpse. This was the failed results for the leg:
Overall, I learned a little more that Sunday and was very happy with the successful results:
I hope you didn’t get spoiled with all the pictures, movies and speedy posts. It will be a little bit before I have another significant update as I am waiting for some parts to arrive. But I hope to show the dome on the top cover and the frame work for both the lightning coils and the main enclosure.

wow
What they said.
That's so cool!

Thank you!
Thanks!!!
Thank you again!
Thanks!!!
These are only a couple of the parts. Within the next week, I should have some of the pictures of the main enclosure. Then it'll start looking like a computer case rather than a nifty casting project I did.
Finally... the motherboard has arrived:
I do think it is funny that the big advertising leaflet that came with my LGA1155 motherboard was for AMD processors. Yeah... Including an AMD processor advertising with an Intel motherboard is like trying to sell reading glasses to a blind man.
Here are both of my new toys: the Gene-Z with the i7-2600k.
Later today, I am doing some more casting and later this week I'll be fabricating the walls for the main enclosure.
And here's the last bit on my shopping list. I still have to wait until the next paycheck before purchasing but I still have over 1.5 months to get this completed.
