In order to be able to see into the chamber, Anatol and I designed a viewport to be attached to the side opposite the vacuum fitting. We cut a slice off of the 5'' aluminum round to be the base and then I used the lathe to put a 2'' diameter hole in the center of the round. In order to have a place to put the viewport, I cut an additional 2 3/4'' diameter hole partially into the round to act as a counter-sink for the port itself. The port was made by cutting a 2'' round piece from a 1/2'' thick slab of acrylic. As per usual, we used J-B Weld to attach the base to the bowl and then the acrylic to the base.
