- 2. Chapter 27 Laminating, Scroll Saw Work and Pyrography
- 3. Laminating
- 4. Laminates Features − Laminates – thin strips of wood (2-3mm) – Stronger than solid wood of same size – Do not warp – Easily formed into shapes – There is a lot of waste – Lots of glue required – Moulds/formers needed to form the shapes
- 5. Laminates used in buildings − Glulam beams are used in buildings
- 6. Laminating Laminates are thin (1mm – 4mm thick) They are glued together to form a thicker piece They can be bent to shape using a former Cramps are used to hold the former closed
- 7. Using laminates Prepare thin laminates (1mm – 4mm) to make up the thickness required Soften the laminates using hot water, so that they bend more easily Apply glue to the surfaces Position laminates in the former with paper around them, to prevent them from bonding to the former Cramp until dry Clean and plane the edges Sand surfaces smooth
- 10. Scroll saw work – fretwork Scroll saw – Cutting detailed shapes from thin pieces of wood – Used to make pictures and jigsaws – Intarsia pictures made from different woods – Keep hands clear of the blade
- 13. Pyrography The art of wood burning Pictures or symbols are burned onto the surface A pyrography tool is used Care must be taken, the tool is very hot
- 14. Quiz
- 15. What type of glue would be used for bonding the laminates of this frame? – PVA glue – Casein glue – Formaldehyde glue
- 16. Explain what laminates are − Laminates are thin strips of wood or veneer − They are about 14mm thick − They are bonded together into shapes
- 17. Name the following piece of equipment and state its use Former − A former is used to contain the laminates and hold them into a defined shape
