After I gave up on finding the part that the bandsaw flung across the room, I got a new tea-strainer spoon to dismantle. While I’d normally mill my own parts, this was already the perfect shape, so hey, why make work for myself?
I used a doubled length of aluminum armature wire to provide the internal shape of the colon. This is a decision that may come back to bite me. I wanted the wire to be flexible enough that I could get it through the opening in the jar but stiff enough that it won’t reshape randomly on its own. In theory, this will work, but I might have to stiffen it further after the colon is in the jar.
I’ve mounted it to the aluminum with plumber’s putty. It’s great stuff that is basically a two part epoxy. It gets almost metal hard and is good for adding stability to structures.
The dark band going around the ball is a band of elastic cord. At the moment this is stitched in place, but once I get the whole thing assembled, I’ll likely pull it out. I’m hoping that the spandex skin of the colon will act as the return and I won’t have to have an extra one internally.
This is probably a vain hope, but you know, a girl can’t help but to be optimistic.
The reason I don’t want the extra return is because it will cause more resistance, which leads to fatigue while doing lipsync. I only want the puppeteer, Jay, to exert the minimal effort to move the mouth.
