USING A FORMER/MOULD/JIG WHEN FORMING FLEXIBLE PLYWOOD
Normally a jig/mould/former is made first. Glue is applied to each layer of flexible plywood. The various layers are held firmly in the jig, for twenty four hours, until the glue is dry.
When the flexible plywood is removed, the layers are permanently glued together, in the shape of the mould/jig.
Using this technique allows several layers of thin flexible plywood to be glued together permanently, forming curved shapes/forms.
The drawing shows how layers of flexible plywood can be formed into unusual shapes.
