• To keep the different parts together in a single
  unit,
• 2 Fishing wire 0.2 diam are inserted in the first
  frame, strechted and glued intothe back.
• Advantages
• 1-more compact assembly
• 2-reduction of dead area
• In the back side the wire is
• Inserted at the tension of 200 g and glued in the
  
• Support basket

The single unit is made of 4 telescopes (FEE
boardBasket). In case of substitution of each
telescope , it need substitute the block
Previous design

Sequence of stack
5
There are several possible three configurations
The basket of the block has a inner cross 0.8
thick to define the positioning of the telescopes
The basket has an internal cross wich is tapered
The basket of the block is made without internal
cross
6
In this case the telescopes are separated with
cross(0.8 thick) DA/AA4.39
In this case the telescopes are
inclined(projecting geometry) DA/AA2.33
