Here is peek under the membrane of my current box project. The idea is that items put in the tray of the box will telegraph through the membrane. As an experiment, I cut and mounted a hundred or so bamboo skewers between two pieces of MDF drilled to accept them. I found a nut that fit on them perfectly. It even cut threads as I screwed them on using a nut driver.
The mock-up of the top is working and I'm pleased with how the rubber dye worked on the latex top. It has a very organic look to it--kind of like frog's skin or some sort of granite.
I have a couple of other ideas and I'm hoping to get one of them sorted out tomorrow. I'll post that one when it's done.
