Re: Daft Punk Thomas Bangalter helmet build
I was completely inspired by you and started work on my own Guy-Man helmet. I'm doing the Tron version:

I'd love to know what you think.
Your progress is enviable! I want to revisit the Guy helmet myself now that I know what the hell I'm doing. You're off to an awesome start, very similar to how I'm planning on tackling that project as well.
how do you make a 2 part mould like how do you make the front part of the mold with out it sticking to the back part?
Huh, I thought I had covered that. I guess I forgot a lot of pics after the molding snafu.
These, technically, are documenting the part of the mold that was scrapped. In redoing the piece, I actually changed the position of the registration keys and added them later so that brushing the silicone on would be easier. The process is otherwise identical.
For separating the two halves, I use this cleaner wax. Smooth-On makes stuff called "Sonite Wax" for this specific purpose, and when this tub runs dry, I might look into that. For now though, this stuff works great.
Well...
pretty great. It doesn't like the brown primer very much, so I have to take pains to only get this wax on the silicone and not on the paint. See the blue painter's tape on the master sculpt there? Thats why that barrier exists.
In prep for molding the front, I added a filler panel underneath and some clay dams along the chin. I also added a small "maker's mark" which will be trimmed off in the end. Not sure how much plastic will even get to this spot, but oh well.
After that it's print coat, thickened coat, and keys. Second verse, same as the first.
You can see in the second pic below how uneven the silicone was because of how I had to brush around the keys. The revised mold half was much cleaner.
The MDF halves in this shot will be for the mother mold. These will make a more even flange, ensuring the sections of the mold jacket stay aligned. The front part of the helmet will also be split into 2 mother mold halves as well - similar to how my Guy helmet has one front section and 2 back halves.
SO! Hopefully I'll be getting the mold jacket finished tonight/tomorrow, then first pulls by Sunday... unless something else goes wrong, then it'll be longer.
