Removed 6" roughing port gate valve and associated plumbing from YBM pump port -> Installed 8" CF Class A blank (borrowed from H2 input mode cleaner pump port) on YBM roughing pump port -> Installed new (but unbaked) 8" CF blank at location of borrowed Class A blank -> Labeled unbaked flange so as to be replaced before exposing to vacuum.
