Step 16

Place the lens holder on the end of the in-

ner lens tube with the glue marks and glue its tabs

to the tube. After drying, check that the inner tube

can be pushed back and forth inside the outer tube.

Then put it aside so that the lens is not damaged

during the rest of the assembly. Tip: If, despite all

caution, you have a mishap with the lens, you can order

a new one from AstroMediaShop.co.uk (OptiMedia lens

no. 10, article No. 314.OM10).

E1. The Door and the Rear Wall

In the rear wall is a small door that can be locked with a ro-

tating bar so that pencils and rolled-up sheets of transparent

paper can be stored in the space below the mirror. First the

door is assembled, then the door is mounted in the rear wall

and the rear wall is fitted to the housing.

Step 17

Glue the two parts of the interior bar [E3

and E4, sheet 7] with their grey sides back to back,

accurately aligned at the edges (Fig. 4 shows a

cross-section of the bar and door).

Step 18

Remove the small disc-shaped bar shaft

[E5] from the door [E2, sheet 2]. Glue the shaft onto

the grey glue marking of the interior bar so that it

sits in the centre of the semi-circle forming the end

of the inner bar. Leave to dry well.

Step 19

Fold the two door handle parts [E7 and E8,

sheet 7] forwards and glue one half of each back

to back. Then glue the resulting handle with the

other two halves onto the grey back of the bar [E6,

sheet 7].

Step 20

Detach the door [E2, sheet 2] from the

rear wall and lay it black side down onto your work

surface. Place the inner bar under the door so that

the disc-shaped bar shaft snaps into its hole in the

door from below. Rotate it a bit so that the axle can

grind into its bearing a little, then turn it so that the

visible part protrudes at right angles from the door.

Put a small amount of glue on the shaft and stick

the door bar with its glue mark onto it. It points

in exactly the same direction as the inner bar, but

is slightly shorter than this. This is intentional to

make it easier to close. Allow the glue to dry thor-

oughly and then carefully move the latch back and

forth until it can be rotated around fully.

Step 21

Lay the rear wall [E1, sheet 2] black side

down onto your work surface and put the door in

the doorway. The bar is turned all the way to the left

so that it does not protrude over the door. Fold the

door hinge [E9, sheet 7] forward once and then flat

again and glue it onto the glue marks located on the

door and door frame. The fold should lie exactly on

the die-cut line. After drying, check the door func-

tions (opening, locking).

Step 22

door

Fold the glue tab of the rear wall backwards

and again fold the three glue tabs of the side walls

and floor, to which the rear wall is glued. Open the

door latch and push the door partly through the

door opening. This way the door handle does not

get in the way when the rear wall is placed on the

work surface to be pressed. Glue the rear wall to the

glue tabs on the base panel and side walls. Its own

glue tab is pointing upwards, just like those on the

other housing walls. Again, make sure that all edges

are flush with the other walls. To dry, lay the case on

its back and put a light weigh on it, e.g. a book.

The housing is now complete, except for the top cover. It will

gain its stability in the next step, when the mirror is fitted

inside and the viewing window is fitted to the top.
