Timber processing and assembly Learning objectives To understand a range of traditional and modern constructional methods and applications when working with timber To be familiar with machinery and jigs that can quicken processing and production

Processing- primary Cutting to length and width- cross-cut and rip Planing- surface planing face and edge, then… Thicknessing to finished dimensions

Processing- secondary Moulding- router or spindle moulder Laminating- flat/curved Steam bending Jointing Using Jigs- dovetail/housing Traditional jointing- permanent Basic mechanical fastenings Knock down/self-assembly fittings

Joining methods Traditional, permanent joining methods including: mortise and tenon,

Traditional joints Dowel joint

Traditional joints Dovetail

Traditional joints Halving joint

Traditional joints Housing joint

Traditional joints Comb or ‘finger’ joint

Knock-down, take apart fittings Barrel nut and bolt Cam fitting Corner plate

Knock-down fittings Screw socket Confirmat screws Block connector

Contemporary joining- Knock Down Advantages for the designer/maker/retailer? Quality assurance Reduced warehousing Advantages for the consumer? Take home-assemble, should be less expensive. Can be dismantled for transport/re-homing Spare fittings should be available

More basic fastenings Nails Round wire nails, oval brads, pins, and commercial drivers. Screws- types and applications

Forming components Laminating (See YouTube clips) Steam bending

Finishing timber Types of finishes Varnish- clear and pigmented Preservatives Oils Waxes Paints Application methods- brush, roller, spray, cloth
