Print out the pages onto thin card.

If you are making the hand cut version, score the dashed lines then carefully cut out the pieces.

Compression Spring

Squeeze to operate this spring. In this mkIII version I’ve concentrated on making the design as simple as possible. The spring is short so that is will fit inside models and it can be constructed without the need for sharp knives.

Fold over the hooks and glue them to make double thickness card.

Fold round and glue the inner and outer bodies then glue the hooks to the marked areas. On the inner slide you can glue the hook on either side depending on in you want the end tabs on the same side or opposite side.

Opposite side version here….

Same side version shown here…

Slide the inner into the outer.

Complete the spring by adding #12 elastic band (1.5in thin)

Tension Spring

Fold up and glue the inner and outer tubes.

On the inner slide you can glue the hook on either side depending on in you want the end tabs on the same side or opposite side.
