This document discusses different types of wood joints used in carpentry including butt joints, miter joints, dado joints, rabbet joints, dovetail joints, mortise and tenon joints, half lap joints, biscuit joints and box joints. It describes each joint, how it is made and its common applications. Key points are that butt joints are the simplest but weakest, dovetail joints add strength to corners, miter joints involve beveling wood pieces and can be strengthened with splines, and mortise and tenon joints are very strong and recommended for furniture and cabinets.

4. WHAT IS A JOINERY?

5. JOINERY
• Is the art of making wood joints. It is the process of
putting together the parts of a piece of project with
the use of some device such as metal fastening and
their attachment.

6. WHAT IS BUTT JOINT?

7. BUTT JOINT
• Is the simplest joint to make since it is
merely involves cutting the wood to
appropriate length and butting them
together. And it is also the weakest because
unless some form of reinforcement is used. It
relies upon glue alone to hold it together.

8. WHAT IS DOVETAIL
JOINT?

9. DOVETAIL JOINT
• Wood work use this option to strengthen
to a corner. It uses interlock joinery of a
series of pins and tails to create a
resilient edge that can be used for
furniture.

10. WHAT IS MITER JOINT
JOINT?

11. MITER JOINT
• Is a joint made by beveling each two
parts to be joined is its weakness but
it can be strengthen with a spline.

12. TWO COMMON VARIATION OF SPLINE
MITER JOINT
• Miter joint,
• one is where the spline is long and runs the length of
the mating surface and another where the spline is
perpendicular to the joined edges.

13. USE OF A MITER JOINT
• Is used when the end grain must be concealed.
For accurate mitering, use a miter box with a
stiffed box saw, or an improvised miter box.

14. WHAT IS RABBET
JOINT?

15. RABBET JOINT
• A rabbet joint is L-shape, cut long the edge
or end of piece of wood. It becomes a
rabbet joint when a piece of wood is butted
into it.
• This type of joint is commonly used for
drawer and book case construction.

16. WHAT IS DADO
JOINT?

17. DADO JOINT
• Dado joint is used in constructing
drawers, shelves, bookcases, and step
ladder. This method is similar to
tongue and groove joint.

18. WHAT IS HALF LAP
JOINT?

19. LAP JOINT
• Wood workers use this joint to join
two boards together to create a flush
surface. It happens most often when
a connection is needed in the middle
of the timber, although corner
connection are also possible

20. WHAT IS DOVE TAIL JOINT?

21. DOVETAIL
• They call it this joinery a dove tail
because it is recommended for its
beauty and strengthen in treasure
box or chest construction.

22. WHAT IS MORTISE AND
TENON?

23. MORTISE AND TENON
• Is a type of joint that connect two
pieces of wood or other material
• In furniture and cabinet making,
mortise and tenon joints are strongest
of wood joint are highly recommended
as they lend durability, strength, and
beauty.

24. WHAT IS CROSS LAP JOINT?

25. • If the joint form in the middle of both
boards, it is called lap joint instead. You
see this wood working joint use for
framing and cabinetry quite often. A
birdsmouth joint is a common variation
used when the connection must be at an
angle.
CROSS LAP?

26. WHAT IS BISCUIT JOINTS?

27. BISCUIT JOINTS
• Wood workers use this technique to create a more robust
version of the butt joint using tongue and groove
principles. Both ends of the timber get a slot cut into
them to hold a small wafer that acts as a connection.
When the glue gets added to the insert, it starts swelling
until the entire carved out area gets filled.

28. WHAT IS BOX JOINTS?

29. BOX JOINT
• This joint works at the end of two timber pieces to
build a seamless right angle. You carve out a series of
symmetrical slots to form rectangular projection
called fingers. This is an effective alternative to dove
tail joint.

30. WHAT IS SLIDING DOVE TAIL JOINTS?

31. SLIDING DOVE TAIL
• Yet another variation of dove tail
joinery is the sliding dovetail joint,
which works like a tongue and
groove while using the dove tail
techniques.

32. WHAT IS FINGER JOINTS?

33. FINGER JOINT?
• This type of wood joint techniques is
mainly used to join two piece of
wood to make a longer board
