A couple more pictures.
The first one shows all the grinding tools associated with the two large lenses. Three of these grinding tools will be used to make polishing laps after the grinding is done. The fourth one (R2) is too thick so I cast an Ultracal30 disk to be used instead.
The second pic shows the improvised wedge error tester I knocked up for the job. The lens sits on three steel balls that have been partially embedded into the steel plate.
