  • Etape 1

    Cut 8 triangular shapes in a flexible mirror band as shown below  (first download the model in the blueprints/plans section).



  • Etape 2

    With hot glue, glue the non-reflective side of the 'reflectors' on large washers to form two '4-petaled flowers'.



  • Etape 3

    Using a drill and a No6 bit, drill a hole in the corner of one of the wood squares.

    In the other square drill 2 holes with a No3 bit (as shown below)



  • Etape 4

    With an M6 bit, drill through the wood slat at the two places indicated.

     

    {#lang_bricoWikiWarnings_warning} It is important to drill the hole at 6cm from the top very straight through the slat.


  • Etape 5

    Glue the side of the square with one hole in the center of the square with two holes and fix from underneath with two screws.



  • Etape 6

    Once the glue of the two 'flowers' is dry, put them on top of each other and fix them toghether slightly with hot glue.



  • Etape 7

    Create a test tube holder. Wrap a wire around the tube and create a kind of hook at its base.



  • Etape 8

    Pass an M6 bolt through a large washer, through the 'flower' on the mirror side and trough the wood slat.

     

    Tighten the other side with a nut.



  • Etape 9

    Loosen the bolt in the center of the reflector. Slide the hook of the test-tube holder under the head of the bolt and tighten everything back.

     

    Insert a small roll of black paper in the test tube (or aluminium foil painted in black).



  • Etape 10

    Fix the reflectors together with a stapler to form a parabola.

     

    Fix a nail on the other end of the slat, perpendiculary to it.

     

    Attach a wire to the CAP securing it with a push pin. Attach the other end of the wire at the edge of the reflector.



  • Etape 11

    Attach the slat of wood and its reflector on the base with a bolt, three washers and a winged nut.



  • Etape 12

    Report the sunglasses model on light cardboard and cut out the shape (the model can be downloaded from the blue prints/plans section.

     

    Cut out the holes for the eyes.

     

    Fold in half the glasses, gluing in sandwich a piece of first aid blanket.

     

    Cut out the shape for the nose.

     

    Make 2 holes on both sides and attach some elastic thread.
