Perspex Sandwiches

Where items are too small or fragile to handle, this method of display protects the objects while allowing the user to look closely from all sides.

Sandwiches consist of 2 outer sheets of perpex, 5mm thick and a plastazote filling, the thickness of which depends on the depth of the object. A hole is cut out of the centre of the plastazote to accomodate the object. The perspex can be cut in-house, but its often more cost effective to ask a local company to make up a batch of blanks. It can cost as little as three pounds for a small pair.

Different sizes on paper

Step 1

Decide on on a number of standard sizes to fit the cases.

Step 2

Sometimes a centre 'diagphragm' of perspex - 2mm thick, is needed if the object is delicate and needs extra support. Holes are drilled in the diagphragm and the object tied on with thread. The thread can be set with paraloid in acetone.

Screw the perspex together

Step 3

All parts are lined up and held in place with tape, so they can be screwed together.

Step 4

Screws should be cut to the right length and filed at the end so they are not sharp.
