I’ve started fabricating the additions to the Neuron Chamber for our upcoming show in Ireland.
One of the most important additions is the High Voltage Manifold, that will house the high voltage wires running from the neon sign transformers to the axons.
For the last installation we ran the wire through soft, black, rubber tube. This was a bit of a last second addition, with the original plan called for sold piping, but we never got to it.
So, what I’m making here are two manifolds, one for each side, that will be mounted on the chamber belly. Between them I’ll run solid pipe. On each end the manifolds will have flexible, metal sheaths that connect to the hemispheres.
Here are the parts for the first manifold. They are each ~3.5′x1.5″. One has a set of large holes for the pipe. One has a set of small holes for the flexible sheath. These will be become pentagons.
Here are two of the above pieces jig’ed up and ready to be tac’ed.
Put five together and look, ohhhh, a pentagon.
And repeat.
The cover is next. We went with perforated steel because we are going to mount a light inside. First I cut a pentagon about an inc greater, and then I notch it.
Then, I “break” the edges.
Break each edge, checking the fit as you go, to insure a snug fit.
At this point I’ve welded on the solid back, and added the mounting tabs.
Here is one of the manifolds mounted on the belly.
Here both are mounted and the pipe is welded in. You can also see the brass nipples (*titter*) that will connect to the flexible hose.
And now it’s done.
