Tech Wall - Building Holds

When we first started this project, we had the idea of building our own holds to reduce costs and so we could easily acquire transparent ones. As the project got further along, the Tech Wall became a secondary project - plus the Adopt-A-Hold project was an excellent fund-raising tool. Now that we've got some more time on our hands, we're once again thinking about the construction of the Tech Wall.

Building climbing holds is not trivial, of course, but it seems like something we could do at least in small quantities. We've done some research and some begging, and hold companies don't want to give us transparent holds (at least not for cheap!) Our first step for this will be, of course, acquiring the materials. There are a few different ways to make them, we'll probably use a resin/sand combination which is popular among hobbyists.

The project will probably go something like this:
1. Make a mold out of clay using a real climbing hold.
2. Make the resin/sand mixture.
3. Pour that into the mold.
4. Wait for it to harden.
5. Realize we screwed up step 2, do steps 2-4 again.
6. We have a hold! Now we experiment with making our own hold shapes/designs and figuring out how to make it more transparent (this sand thing could make it difficult)
