Afterfussing with the setup all afternoon yesterday and another few hours today, I finally glued the first primary prism to the HAM3 PR2. It looks to be off in the d-value disance, but the fixture/microscope setup is such that you cannot check any numbers once the prism is glued and being cured in the fixture.  So, I'll have to wait until tomorrow when the glue is mostly cured to remove the fixture and remeasure everything again.
