Hello, I know I'm a bit out of place in here. But I found a lot of useful info in these forums. I hope my project will be welcomed with open arms. I am seeking for good advice since this is my first scratchbuild project, with no experience what so ever. I will keep posting my progress with pictures and stuff so others can learn from it as well. So here goes: The project consists of 3 chapters. First, building my positive out of clay. Second making a mold out of plaster. And third building the helmet with carbonfibre and glassfibre. I know this project can cost me a lot more than buying a new premade helmet, but I'm shure you guys know why I'dd wanna do this...
Chapter one: "Sculpting my positive".
Look at the attachements if you need visual confirmation.
- I built an armature for my helmet out of wire of clothing hangers and mesh wire. So it fits the inside of my previous skydiving camerahelmet.
- Applied lot's of SuperSculpey on top of my armature until all outside was covered, and started sculpting the main form.
- I added more detail to the helmet for the topmount camera (that will be later boxed inside) and place for two audible altimeters... I tried to smooth out the dome's surfaces just by rolling a big *** battery from my radio on it. I just don't have any tools hahaha. Improvising all the way.
So this is the point at where I'm at. And here is where I need your expertise on the following questions:
I would really appreciate your help and hope to get to the next chapter next week. If you find a lot of spelling errors, please don't hang me for it. I learned it all by watching TV hehehe.
- What other tools than a simple battery can I use to make the curves flawless?
- How can I smooth out all of the surface the best way. I read some stuff about rubbing alcohol.
- Do I need to cover the inside of the clay helmet for baking?
- Will my mother get pissed if she returns after a week of holiday if I bake this stuff in her oven?
- I'm not shure there is air trapped inside because I worked the sculpting by placing layers on each other, will this give problems baking it?
