(Jordan, Travis, Gerardo)

The relay tube connecting HAM5 and HAM7 was removed.  We had a few snags while removing it, for some reason the space between bellows is tight, perhaps due to the difference between pressure states, one chamber is under vacuum the other is not.

After the tube was out, the viewport was installed on a short assembly, the viewport and the entire assembly was leak checked and no leaks were found.  He background a the leak detector remained at 1.0x10^-10 torr*l/sec during the leak testing.

System is currently being pumped down via a small turbo plus an aux cart.
