joints Flashcards
properties of a butt joint
simplest method of joining timber
relies upon adhesives such as pva
advantages of butt joint
- easy to complete
- the pieces to be joined are cut square, pva is applied and then the joint is clamped dry
disadvantages of butt joints
- only suitable for very lightweight applications such as modelling
properties of dowel joints
- small round pegs made from a hardwood
- they come in a range of timbers in different thicknesses
advantages of dowel joint
- simple joining process- stronger tgan using a butt joint because tge dowels interconnect the two pieces
- easy to use, do not require skills or complex tools
disadvantages of dowel joints
- requires precise drilling and alignment- can sometimes be challenging
- needs specific tools like a dowel jig, drill and dowels
possible uses of dowel joints
- typically used in flat pack furniture such as bookcases and wardrobes
mitre joints properties
- similar to butt joints- they rely upon simply gluing and clamping the pieces together- at a 45 degree angle
mitre joints advantages
- easy process- using an angled belt sander usually
mitre joints disadvantages
- sometimes its quite a weak joint
- not always secure- glued together

comb joint properties
- the combs create an increased gluing surface area
comb joint advantages
- make a strong joint
- comb joints can be cut relatively easily using a band saw or laser cut- or with more skill using a tenon saw and wood chisel
comb joint disadvantages
requires accuracy to be able to interlock
comb joints uses
- commonly used to make boxes- perfect for this application because the two piece’s interlock
dovetail joint properties
- have directional strength
dovetail joint advatages
- once glued together, its nearly impossible to pull them apart
- can be cut by hand using a dovetail saw, or more commonly machined with a router and jig that requires less skill
dovetail joint disadvantages
- can be fairly difficult to mark out and cut, requires skill and practice
dovetail joint uses
- used in making drawers- directional strength- excellent for joining the front and back of a drawer to the sides
mortise and tenon joint properties
- involves making a square or rectangle hole- known as a mortise
- this might be done with a mortise machine or router, or by simply drilling and cutting using a chisel
advantages of mortise and tenon joint
- strong
- durable
mortise and tenon joint disadvantages
- can be difficult to cut the hole without specialist tools
- may require specialist, complex tools
mortise and tenon joint uses
- used to make heavy duty frame constructions for furniture or similar applications
housing joint properties
- a groove is cut into one piece, and the end of the second piece is inserted into it
