The roller coaster car got it's electric orange colour applied this morning. 2 coats covered extremely well, even though it was as bright orange as it was.
We also started the big brain that will be shot in a bell jar. The jar is HUGE. Well it's huge for a bell jar to me anyways! It stands 20" tall and about 9" in diameter. Filling it will take a rather large brain. A normal size brain model from a medical supply place is pretty small, and would look puny in this colossal jar. So we're making one. We are lucky to have complete control on this job, whatever we like, we can do. They are shooting this 2 ways. One way will have the jar and brain upside down and filled with a liquid of some kind, and they'll flip it in post, and the other way will be the right way up with no liquid. I could have sculpted a brain out of the many weird products we have here by hand, BUT all those materials would be solid and opaque, and that's pretty boring I think. I want it to GLOW! So I found a pretty cool 3d model brain on line and downloaded it. I usually do that first for generic things. Why model it if one exists already.
I quickly found out that the original geometry wasn't all that great to begin with, and after the sculpting, it was a real mess. It looks good, but it's a mess. And all this messed up geometry means Hexagon doesn't want to split it how I want it to. I can't bring this into Aspire the way it is, as all the undercuts would be filled, and not to mention it's thicker than any one material I have. Long story short, I need to slice it. After thinking about it, I decided on a new approach. I would strategically place cubes around it, then remove the cubes in Aspire, leaving the portions of the brain I need.
Here's how one piece looks when I'm importing it in to Aspire. All the cubes come in, with the brain and I'll just trim them off after they've been pasted down.
Now for the fun part! I don't want to machine this as the final piece. I want to make a mold. I said before that I wanted it to glow, and we have clear casting resin in stock that hardens up in around an hour. I could have machined the brain as a 'positive' shape, and made a rubber mold. But this would have required waiting overnight for the mold, then we would have had to make a "jacket" to support the rubber mold, then the couple of hours for the resin to harden up. We just don't have the time on this, it shoots on Thursday.
After all the parts were trimmed on the saw, I heavily coated the gluing surfaces with Super 77 spray contact cement. I used alot of it in hopes to create a seal so the resin wouldn't poor out the seam joins.
