7 Shelves on 1 st pillar Use identical, short shelves => up-down symmetry, lines only in outside raw. Shelves are adjustable in x and y by +/- 10mm

11 Tool for adjusting shelf to C-frame This tool helps: 1)make runners on shelf perpendicular to one C-frame (in x-z plane and in y-z plane) 2)adjust (in x and in y) shelf to hole in one C-frame for every shelf on nearest C-frame in hole without mask holder |(2 nd C-frame)-(far end of 1 st new middle shelf)|-5= =501  500 x y Then adjust shelf versus cylinder z y Pillar (on sides) front view side view C-frame stop mechanism ON First install cylinder
