Over the last 2 days, Gerardo and I glued the prisms and the bump stop mounts to the CP destined for use in the ITMx QUAD suspension.  We had trouble using the ergo arm because the edge of the First Contact sheet on the AR surface crossed the border of the ergo arm o-ring many times causing it to not seal onto the mass.  Pictures of the prism glue joints attached.  View is from looking inside glass at the 2 line contacts of each prism.
