Wood Processes

Question 1

Addition/fabrication

Traditional wood jointing

Dovetail
Finger 
Housing 
Half lap
Dowel
Mortise and tenon

Answer 1

Dovetail - multi directional strength. Used for drawers
Finger - box construction
Housing - framework construction and shelving
Half lap - simple frames or boxes
Dowel - flat pack typically
Mortise and tenon - frame construction for tables and chairs

Question 2

Component joining
KD fittings
What are they used for
2 ADV

Answer 2

Knock down fittings
Used for flat pack furniture
Easy to use with limited number of simple tools
Wide range of standardised KD fittings interchangeable. Used in wide range of p.

Question 3

KD fittings

Modesty blocks 
Barrel nut and bolts 
Cam lock interconnectors 
Wood screws 
Coach bolts

Answer 3

Modesty blocks - small rigid polymer blocks that have moulded holes for screws, join blocks to panels. Used on cupboards and storage units

Barrel nut and bolts - cross dowel fitted in 1 of the pieces to be joined. Bolt inserted through other piece of timber and is tightened into cross dowel

Cam lock interconnectors - metal dowel into pieces. CAM is a disk that fits into pre drilled hole. Disk rotated with screw driver, the collar on the dowel locks into cam and pulls both pieces together. Used in bookcases where horizontal shelves attached to sides (bunk bed)

Wood screws - screw 2 pieces of wood. Top wood fired drilled, then is screwed into bottom which had a pilot hole that is thinner than thread.

Coach bolts - join wood pieces together. Under the head there’s a square piece that digs into the wood when tightened, which prevents bolt from rotating. Used in doors and street furniture eg wooden benches.

Question 4

Forming processes

Lamination
What does it bond & how
What does it use to hold it in place

Steam bending
What does it use to allow it to be used on a former
ADV of this over laminating

Answer 4

Lamination:
Bonds material together
Uses veneer or thin manufacured board, can be glued together, bent over former = thicker board in shape of former
Held by clamps or vacuum bag when drying

Steam bending:
Combines heat and steam to make strips of wood pliable so it can be shaped over a former.
Wood placed in stream box where it absorbs steam. Then bent over a former and clamped till it dries.
Quicker & less wasteful than laminating, as u have to wait for glue to dry and parts need to be trimmed

Question 5

Machine processes
Turning (3 types) and what do they each do

Milling
What type of job is it used for
2 Dis and 1 ADV

Routering

Answer 5

Turning:
Turning between centres - machine a spindle eg chair or table legs
Turning on a faceplate - machine items like domes or bowls
Turning in a chuck - used to grip item while being machined, eg drilling end of spindle.
Look at video of guy making cool stuff on lathes

Milling:
Used for small jobs eg prototyping or roughing it a small hole
Slow processes, don’t have large work area as CNC routers
Can be manual or CNC

Routering:
Used to machine slots or holes in wood, make decorative mouldings eg table tops
Can be manual plunge routers or CNC
