We spent most of the day adding braces to the various parts of the dome. We also installed the slip rings to provide power to the motors on the dome while it rotates. We expect to finish the dome assembly by the end of the day tomorrow.

Installation of the second "pipe brace," which strengthens the dome and helps keep it round.

Installation of the third pipe brace.

All of the pipe braces installed.
