Tauruscat: Completed Sensor

After several coats of Liver of Sulphur and one coat of wine vinegar I have completed the sensor tube fittings.

Shown along with the sensor is a polished brass fitting to show how much it darkened with treatment.

Tauruscat: The Sensors

Now it is time to fill those eleven holes in the Tauruscat helmet with brain wave sensors. I dug through my somewhat extensive collection of yard sale finds looking for something appropriate, and found a cast iron lamp part (I think). It has a certain Victorian look to it, and so I'm using it as my base. Attached to it (on the left in the photo) is a short pipe (on the bottom) and a barbed brass hose fitting (on the top).

I filled the holes in the bottom of the iron casting with steel ball bearings, and fabricated a black acrylic collar (towards the top) that will fit over the rubber tubing. I then molded the whole thing in silicone rubber, and cast the parts in black urethane (middle of photo). For the final look I antiqued it in the fruitwood wood stain (on the right) so that it would resemble rusty cast iron.
