Woodworking Joinery Techniques 1 — Questions and Answers
Question 1: What is a mortise and tenon joint?
- A joint where a projecting tenon fits into a corresponding mortise cavity (Correct answer)
- Two boards glued edge to edge
- A joint held together only by nails
- A lap joint secured with screws
Correct answer: A joint where a projecting tenon fits into a corresponding mortise cavity
A mortise and tenon joint consists of a projecting tenon cut on one piece that fits precisely into a mortise (cavity) cut in the mating piece, creating a strong mechanical connection.
Question 2: What is a dovetail joint primarily used for?
- Joining drawer corners because of its resistance to being pulled apart (Correct answer)
- Joining two boards end to end
- Connecting table legs to the apron
- Filling gaps in wood panels
Correct answer: Joining drawer corners because of its resistance to being pulled apart
The dovetail joint's interlocking trapezoidal pins and tails provide exceptional resistance to tensile forces, making it ideal for drawer construction.
Question 3: What is a biscuit joint used for in woodworking?
- Aligning and reinforcing edge-to-edge glue joints using football-shaped compressed wood wafers (Correct answer)
- Decorative inlay work on tabletops
- Connecting mitered frame corners with hidden fasteners
- Joining boards end to end for extra length
Correct answer: Aligning and reinforcing edge-to-edge glue joints using football-shaped compressed wood wafers
Biscuit joints use a biscuit joiner to cut matching slots into mating boards; compressed beech biscuits inserted with glue swell to align and strengthen the joint.
Question 4: What is a rabbet joint?
- A step-shaped recess cut along the edge or end of a board that receives another board (Correct answer)
- A joint made with a wooden peg through two overlapping boards
- A V-shaped groove cut across the grain
- A joint that uses metal brackets for reinforcement
Correct answer: A step-shaped recess cut along the edge or end of a board that receives another board
A rabbet is an L-shaped channel cut along the edge or end of a piece of wood that allows another board to nest into it, commonly used in cabinet backs and drawers.
Question 5: What is a box joint (finger joint) used for?
- Joining box corners with interlocking rectangular fingers for a strong glue surface (Correct answer)
- Connecting wide panels edge to edge
- Attaching cabinet hardware to doors
- Joining boards at an angle other than 90 degrees
Correct answer: Joining box corners with interlocking rectangular fingers for a strong glue surface
Box joints use evenly spaced rectangular interlocking fingers that greatly increase the glue surface area, making them strong and attractive for box and drawer corners.
Question 6: What is the purpose of a dado joint?
- To house the end of a shelf or divider panel within a groove cut across the grain of a board (Correct answer)
- To join two boards at a miter angle
- To add decorative molding to a cabinet edge
- To connect two boards end to end in a straight line
Correct answer: To house the end of a shelf or divider panel within a groove cut across the grain of a board
A dado is a flat-bottomed groove cut across the grain of a board that accepts the end of a shelf or panel, providing strong mechanical support against sagging.
