- The surface of
a jig must be well finished.
- To prevent the
grain of a wooden jig from appearing on the shaped plastic it may be
a good idea to cover the wooden jig surface with card or other smooth
materials.
- When making simple
bends or curves in thin plastic you may wish to make the jig shown in
this unit. The heated, soft plastic slides into the jig and is held
there until it resets.
- This type of jig
can be made from scrap wood or MDF. The curve in the wooden block may
be sanded on a belt sander and covered with card or another smooth material.
- The jig can be
held in a vice when inserting the plastic. Protective gloves should
be worn when handling hot plastic.
- The disadvantage
of this jig is that although it accommodates a variety of material widths
it does not accommodate a variety of material lengths.
