This isn't all together yet, but for now...

I built a mold box for the tube, and poured it in several layers. This was an experiment to see if the tube would implode when the resin set. Luckily, nothing happened, and the tube still functions through all the nasty resin. I had to be sure all the wiring was accessible, so I tied all the lines neatly out, before I poured the resin.

Next thing to do is sand and polish, then hook it up. It's heavy.

Reminds of those prehistoric bugs stuck in amber.
