| An extra piece of 4in x 1in timber 3 foot 3 inches long is bolted to the centre face of each of the small boxes to act as the 'locking plate board'.
|
 |
|
The holes for the bolts are well countersunk, since the steel locking plate will be screwed to the outside face (next week).
|
|
Rectangular pieces of 3/8th inch plywood is cut to fit the tops of each small box. These are laid in place at present and not fixed.

We now make the sliding tray for the centre. This is made of a piece of 3/8th inch plywood, 2foot 6 inches by 5 foot.
|
 |
|
The two long sides are edged with 4in x 1in timber 57 inches long, such that one and a half inches of ply protrudes at each end.
The underside is strengthened by five pieces of 2in x 1in timber. |

The picture to the left shows the top side of the sliding tray. The protrusion of the plywood is clear.
|
| The sliding tray is placed in the centre space of the unit. The pictures below show the tray moved slightly to one side for clarity.
