Re: Fallout 3: Mini-Nuke WIP
I am a very happy boy. The mold did not come out perfect, but it gets the job done. The rubber is thicker so it doesn't flop around while I do the rotocasting. The main problem is that I screwed up the keys again. This time I put too many and they are all very tight fits. It took me around 20 minutes to get just the bottom half back into the the shell. The other problem is that the shell or even the entire mold should have been three parts instead of two. There is a LOT of vacuum to fight when it comes time to pull the cast.
Speaking of casts, the one that came out bad about a month ago and had to be fixed is on the left, the one I pulled from the mold this morning is on the right. The opening is so large on the new cast because I was testing something farther down the post. The black line is where I was making the parting line for the mold halves.
It is that funky green color because I was also using this as a test for another prop I want to make later on. Unfortunately, the color is good, but the bubbles on the inside ruined the effect I was after. In case anyone cares and for my own future reference that was two or three drops of So Strong geen in three ounces of SmoothCast 65D. There were two problems and they were both my fault:
1. The material on the top is very thin.
2. Not all of the plastic cured. That is because I over filled the cup I was mixing it in and I did not want to spill it all over me. That is what the dark areas are and why I have it on a plastic bag.
The seam is not too bad. And as I feared, some of the screw details are not what I was hoping for.
The reason I made the opening so large is because I wanted to test a nose cone I made for one of the earlier failures.
It is a pretty good fit which saves me a lot of work, but I need to compare that picture with my reference pictures. I do not think it will take too much work to get it right.
So I am happy with the results so far. Could it have been better? Of course, but hey it's pretty darn good for a first prop. And frankly, I've seen pictures of people fixing worse kits that cost big bucks. I also liked feeling all professional using the one gallon package of SmoothCast instead of the little trial versions.
