The new 5/16 bolts worked well with the adaptor plate, and the optic was removed from the chamber. The optic was wrapped and secured on the Straddle Lift, and the Straddle Lift was lowered to it's lowest level, for transporting the optic to the optics lab. FYI: the class-B hardware for lifting the "lift table" in and out of the chamber, was installed in a way that didn't make sense to me, and others agreed, so we reworked the hardware configuration for lifting the lift table - picture will be attached.
