Question 1Woodwork

Which hand tool is used to check whether a board face is flat and true before planing?

  1. A mortise gauge
  2. A winding sticks pair Correct answer.
  3. A marking gauge
  4. A try square

Explanation

Winding sticks are two straight, parallel-sided bars placed across the ends of a board and sighted along; any twist shows as the top edges appear to cross. They test flatness and wind, not squareness of an edge.

Question 2Woodwork

A rip saw differs from a crosscut saw mainly because its teeth are filed to cut

  1. metal with hardened teeth
  2. along the grain with chisel-like points Correct answer.
  3. curves with a narrow tapered blade
  4. across the grain with knife-like points

Explanation

Rip teeth are filed in a chisel profile that severs fibres running the length of the board, so the saw works along the grain. Crosscut teeth are bevel-filed to knife through fibres across the grain.

Question 3Woodwork

What is the standard purpose of a bench hook when working with a tenon saw?

  1. To set the depth of a saw cut
  2. To hold the workpiece against sawing thrust Correct answer.
  3. To guide a chisel at 90 degrees
  4. To clamp a board for planing

Explanation

A bench hook hooks over the bench edge, and its stop resists the forward push of the saw so the workpiece stays put. It is a simple sawing aid, not a depth stop or chisel guide.

Question 4Woodwork

Which abrasive grit sequence is the correct progression for smoothing a hardwood surface?

  1. 60, then 120, then 240 Correct answer.
  2. 240, then 120, then 60
  3. 120, then 240, then 60
  4. 120, then 60, then 240

Explanation

Abrasive grit numbers indicate particle size, so you start coarse and move finer to remove scratches left by the previous grit. Jumping back to a coarser grit reintroduces deep scratches that must be sanded out again.

Question 5Woodwork

A No. 4 bench plane is best described as

  1. a smoothing plane for final surface finishing Correct answer.
  2. a router plane for cleaning grooves
  3. a small block plane for end grain
  4. a long jointer for truing edges

Explanation

The No. 4 is a short-bodied smoothing plane used to take fine shavings and level the surface after truing work. Its length suits finishing rather than flattening long boards.

Question 6Woodwork

Which timber defect describes a board that has cupped, bowed, or twisted after drying?

  1. Shake
  2. Wane
  3. Distortion Correct answer.
  4. Knot

Explanation

Distortion is the general term for drying-related movement such as cup, bow, twist, and spring. It results from differential shrinkage as moisture leaves the timber unevenly.

Question 7Woodwork

The main safety reason for keeping chisels sharp is that a sharp edge

  1. cuts faster so fewer passes are needed
  2. requires less force and is easier to control Correct answer.
  3. leaves a smoother finish on end grain
  4. lasts longer between honings

Explanation

A dull edge needs more pressure to cut, and that extra force makes the tool more likely to slip suddenly. A sharp chisel bites with light control, reducing the chance of injury.

Question 8Woodwork

When gluing a joint, what does adequate clamping pressure mainly achieve?

  1. It speeds up the curing reaction chemically
  2. It forces excess glue out and brings surfaces into close contact Correct answer.
  3. It increases the open assembly time of the glue
  4. It waterproofs the joint against moisture

Explanation

Clamping brings the two surfaces into intimate contact and squeezes out surplus adhesive so the glue line stays thin. A thin, uniform glue line is far stronger than a thick, starved or gappy one.

Question 9Woodwork

A board is 1.8 m long. How many millimetres is that?

  1. 18 mm
  2. 18 000 mm
  3. 1 800 mm Correct answer.
  4. 180 mm

Explanation

One metre equals 1 000 millimetres, so 1.8 m multiplied by 1 000 gives 1 800 mm. Converting to millimetres simply moves the decimal three places to the right.

Question 10Woodwork

A mortise-and-tenon joint is being cut. Which part should be made slightly shorter than the mortise depth to allow for glue squeeze-out?

  1. The tenon's end grain Correct answer.
  2. The shoulder of the tenon
  3. The haunch of the tenon
  4. The mortise's side walls

Explanation

The end of the tenon is left a fraction short so glue and trapped air can escape and the shoulders seat fully. If the tenon bottoms out, the joint cannot close and the shoulders stand proud.

Question 11Woodwork

Why is a dovetail joint preferred for drawer corners rather than a simple butt joint?

  1. It needs no marking out before cutting
  2. It requires no glue to hold
  3. It allows the drawer to be dismantled repeatedly
  4. It resists pull-out because the tails and pins interlock mechanically Correct answer.

Explanation

The flared tails are wider at their ends, so the joint locks against the pull of the drawer front. This mechanical resistance, plus glue area, makes it far stronger than a butt joint under tension.

Question 12Woodwork

A panel door is being assembled with a solid wood centre panel. Why is the panel left slightly loose in its grooves?

  1. To reduce the weight of the door
  2. To let the panel shrink and swell with moisture changes Correct answer.
  3. To allow the frame to be dismantled
  4. To allow glue to reach the panel edges

Explanation

Solid wood moves across the grain as humidity changes, so a panel trapped tightly would split or force the frame apart. Leaving clearance in the groove lets the panel float while the frame stays rigid.

Question 13Woodwork

When planing a board's edge square, why is it good practice to alternate between the two faces when checking with a try square?

  1. It reveals any error doubled, so the edge can be corrected Correct answer.
  2. It stops the board from cupping
  3. It keeps the plane iron sharp for longer
  4. It prevents the plane from tearing the grain

Explanation

If the edge is out of square, checking from both faces shows the error reversed each time, which doubles the visible deviation. That makes it easy to judge which side needs more planing.

Question 14Woodwork

Which adhesive type is most suitable for an exterior garden bench that will be exposed to rain?

  1. Polyurethane or resorcinol-formaldehyde adhesive Correct answer.
  2. Starch paste
  3. Animal hide glue
  4. Polyvinyl acetate (PVA) white glue

Explanation

Exterior work needs a waterproof adhesive; polyurethane and resorcinol-formaldehyde both cure to water-resistant bonds suited to damp conditions. Standard interior PVA and hide glue soften or creep with moisture.

Question 15Woodwork

A cabinetmaker needs a flat, stable sheet for a kitchen cabinet door with a painted finish. Which material is most appropriate?

  1. Green oak planks
  2. Laminated veneer lumber
  3. Medium-density fibreboard (MDF) Correct answer.
  4. Solid oak boards edge-jointed

Explanation

MDF is a homogeneous panel with uniform density, so it stays flat and takes paint smoothly without grain movement. Solid timber would move seasonally and show grain through the finish.

Question 16Woodwork

A chisel is being honed. What is the purpose of the micro-bevel created on the flat face?

  1. To soften the edge for delicate work
  2. To reduce the area needing polishing and speed honing Correct answer.
  3. To increase the cutting angle to 45 degrees
  4. To make the chisel suitable for mortising only

Explanation

A micro-bevel on the back removes the burr while polishing only a narrow strip, so honing is quick and the edge stays keen. The bulk of the flat face remains untouched.

Question 17Woodwork

Which factor most affects the amount a solid timber board will move across its width with seasonal humidity change?

  1. The colour of the finish applied
  2. The length of the board
  3. The sharpness of the saw used
  4. The species and the orientation of growth rings Correct answer.

Explanation

Movement across the grain depends on the species' shrinkage rate and on how the rings are oriented; quarter-sawn stock moves less than flat-sawn. Length has almost no effect because movement along the grain is minimal.

Question 18Woodwork

When using a router table to cut a rebate, why should the workpiece be fed against the rotation of the cutter?

  1. To reduce the depth of cut automatically
  2. To keep the cutter cool
  3. To increase the cutter speed
  4. To prevent climb cutting and loss of control Correct answer.

Explanation

Feeding against cutter rotation gives a conventional cut where the cutter pulls the work into the fence, keeping it controlled. Feeding with rotation is climb cutting, which can snatch the workpiece.

Question 19Woodwork

A piece of timber is described as having a moisture content of 12 percent. What does this mean?

  1. The wood contains water equal to 12 percent of its oven-dry mass Correct answer.
  2. Twelve percent of its volume is air
  3. Twelve percent of its fibres are decayed
  4. The finish covers 12 percent of the surface

Explanation

Moisture content is the mass of water in the wood expressed as a percentage of the oven-dry mass of the wood. It is measured by weighing before and after drying.

Question 20Woodwork

A woodturner is roughing a spindle between centres. Which practice best reduces the risk of a catch?

  1. Forcing the tool into the wood at high speed
  2. Presenting the gouge with the bevel rubbing and cutting downhill Correct answer.
  3. Using a skew chisel flat on its side
  4. Starting the lathe before locking the tool rest

Explanation

Riding the bevel first supports the cutting edge and lets the gouge slice rather than dig, which avoids a catch. Cutting downhill follows the grain and gives a cleaner, safer cut.

Question 21Woodwork

A drawer runner is binding in its groove only in humid summer weather. What is the most likely explanation?

  1. The drawer bottom has swollen across the grain Correct answer.
  2. The finish has become harder
  3. The glue has crystallised
  4. The runner has shrunk along the grain

Explanation

Solid wood swells as it absorbs moisture, and the movement is greatest across the grain. A drawer bottom or runner that swells in humid conditions will bind in a tight groove.

Question 22Woodwork

A cabinetmaker is choosing between a stopped chamfer and a through chamfer on a leg. Which consideration makes a stopped chamfer preferable on a visible face?

  1. It avoids cutting across the end grain at the corners Correct answer.
  2. It is quicker to cut with a router
  3. It removes less material overall
  4. It makes the leg stronger in compression

Explanation

A stopped chamfer terminates before the corner, so it avoids the awkward cross-grain cut and keeps the corner crisp. This is a design and workmanship decision rather than a strength one.

Question 23Woodwork

A workshop shows a white, powdery deposit on the surface of an oak frame near a damp wall. Which explanation is most consistent?

  1. A reaction between the oak tannins and the iron fixings
  2. Efflorescence from salts drawn through the masonry Correct answer.
  3. Insect frass from woodworm
  4. Fungal decay producing fruiting bodies

Explanation

A white powdery bloom on or near damp masonry is characteristic of efflorescence, where soluble salts migrate to the surface as water evaporates. It is a moisture symptom rather than a timber defect.

Question 24Woodwork

A workshop needs to produce 40 identical drawer sides with a dovetail pattern. Which approach best balances accuracy and setup time?

  1. Cutting each joint entirely by hand with a dovetail saw
  2. Using a router with a dovetail jig and template Correct answer.
  3. Using a bandsaw for all joints
  4. Marking each joint with a knife and square

Explanation

A dovetail jig with a template lets a router reproduce identical joints quickly once set up, which suits batch production. Hand-cutting 40 identical sets is slow and introduces variation.

Question 25Woodwork

A woodworker is finishing a table with a film-forming finish over an oil-based stain. Why should the stain be fully dry before the topcoat is applied?

  1. The topcoat will cure too quickly
  2. The topcoat will not adhere and may blister or lift if solvent is trapped Correct answer.
  3. The stain will lose its pigment
  4. The stain will change colour permanently

Explanation

Trapped solvent from an incompletely dry stain can migrate into the topcoat, causing blistering, lifting, or poor adhesion. Allowing full drying lets the solvent escape before the film seals the surface.

Question 26Woodwork

Which handsaw is designed for cutting joints and fine work because it has a stiffened back and small teeth?

  1. Coping saw
  2. Crosscut saw
  3. Tenon saw Correct answer.
  4. Rip saw

Explanation

A tenon saw has a rigid brass or steel back that keeps the thin blade straight, and its fine teeth (typically 10–14 TPI) suit accurate joint cutting. Rip and crosscut saws are large hand saws without a stiffened back, and a coping saw is for curved work.

Question 27Woodwork

What is the primary purpose of a bench hook when crosscutting a small piece of timber by hand?

  1. To guide the saw at exactly 45 degrees
  2. To collect sawdust for reuse
  3. To hold the work against the bench edge so it does not slip Correct answer.
  4. To measure the length of the cut

Explanation

A bench hook has a stop that hooks over the bench edge and an upper stop that the workpiece is pushed against, so the timber is held firmly while the saw cuts. It provides no angle guidance or measurement function.

Question 28Woodwork

Which abrasive grit number would be chosen for the final smoothing pass on bare timber before applying a clear finish?

  1. 60 grit
  2. 120 grit
  3. 240 grit Correct answer.
  4. 80 grit

Explanation

Grit numbers indicate particle size: higher numbers are finer. Final smoothing before finishing is normally done with 180–240 grit, so 240 is the correct choice from this list. Coarse grits leave visible scratch marks.

Question 29Woodwork

In woodworking, what does the term 'nominal size' mean when applied to prepared timber?

  1. The size including any preservative coating
  2. The size after planing to finished dimensions
  3. The size measured only across the thickness
  4. The size before any planing or machining Correct answer.

Explanation

Nominal size refers to the stated size of timber before it is dressed or planed. Once surfaced, the actual finished size is smaller, which is why a nominal 50 mm board may measure around 44 mm after planing.

Question 30Woodwork

Which type of drill bit is intended for boring clean, accurate holes in wood and has a central point and two spurs?

  1. Twist bit for metal
  2. Hole saw
  3. Masonry bit
  4. Brad-point bit Correct answer.

Explanation

A brad-point bit has a sharp centre point that locates the hole and spurs that score the rim, giving clean entry and exit in timber. Masonry bits are for brick and concrete, and a hole saw cuts large-diameter holes.

Question 31Woodwork

What is the main reason for using a try square rather than a steel rule when marking a line across a board?

  1. It measures in millimetres more accurately
  2. It protects the timber surface from marks
  3. It references the board's edge so the line is square to it Correct answer.
  4. It can mark curves as well as straight lines

Explanation

A try square has a stock that is pressed against the board's face or edge, so the blade is held at 90 degrees to that reference. A rule alone cannot transfer a square line from the edge.

Question 32Woodwork

Which wood is classed as a hardwood because it comes from a broad-leaved tree?

  1. Oak Correct answer.
  2. Pine
  3. Fir
  4. Spruce

Explanation

Hardwoods come from deciduous broad-leaved trees such as oak, ash and beech, while softwoods come from conifers such as pine, spruce and fir. The classification is botanical, not a statement of actual hardness.

Question 33Woodwork

What does the term 'saw kerf' describe?

  1. The set pattern on alternate teeth
  2. The angle of the saw teeth
  3. The length of the saw blade
  4. The width of the slot removed by the saw blade Correct answer.

Explanation

The kerf is the width of the cut made by the saw, determined by the blade thickness plus the amount of set on the teeth. It matters when cutting joints because the kerf removes material.

Question 34Woodwork

A cabinetmaker needs a strong right-angled frame joint that hides the end grain on the face and can be pinned. Which joint best fits?

  1. Mitre joint reinforced with a spline Correct answer.
  2. Through dovetail
  3. Lap dovetail
  4. Housing joint

Explanation

A mitre joint presents a clean corner with no end grain showing on either face, and a spline or key adds the gluing area and strength that a plain mitre lacks. Dovetails deliberately show end grain, and a housing joint is for shelves.

Question 35Woodwork

When sharpening a plane iron on a waterstone, why is the back of the blade lapped flat first?

  1. To increase the bevel angle
  2. To remove rust from the cutting edge only
  3. So the honed bevel meets a flat face and produces a keen, straight edge Correct answer.
  4. To reduce the overall thickness of the blade

Explanation

The cutting edge is the intersection of the bevel and the flat back. If the back is not flat, the edge cannot be truly sharp, so the back is lapped flat before the bevel is honed.

Question 36Woodwork

A timber board has a moisture content of 20 percent and is to be used indoors where equilibrium moisture content is about 10 percent. What is the likely consequence?

  1. The board's density will increase as it dries
  2. The board will shrink across its width as it dries Correct answer.
  3. The board will expand across its width as it dries
  4. The board's length will shorten noticeably

Explanation

Wood shrinks as it loses moisture below the fibre saturation point, and movement is greatest across the width (tangentially and radially) rather than along the length. Drying from 20 to 10 percent therefore causes measurable width shrinkage.

Question 37Woodwork

Why is a crosscut saw sharpened with knife-like teeth that sever fibres rather than chisel-like teeth that lift them?

  1. Crosscut teeth are easier to file than rip teeth
  2. Crosscut saws are used only on softwoods
  3. Cutting across the grain severs fibres, so a slicing edge gives a cleaner end Correct answer.
  4. The teeth need to clear dust faster than rip teeth

Explanation

When cutting across the grain, the fibres run at right angles to the cut, so pointed, bevelled teeth slice the fibres cleanly. Rip teeth are chisel-shaped to chisel out material along the grain.

Question 38Woodwork

A woodworker is gluing up a frame and needs time to assemble several joints before the glue grabs. Which adhesive property matters most?

  1. Colour of the cured glue line
  2. Bottle size
  3. Open assembly time Correct answer.
  4. Shelf life of the unopened bottle

Explanation

Open assembly time is the working period during which the adhesive still allows parts to be positioned and clamped. A complex glue-up needs a longer open time than a simple one.

Question 39Woodwork

When setting out a mortise, why is the mortise usually cut first and the tenon then fitted to it?

  1. It is easier to pare a tenon cheek to fit an existing mortise than to enlarge a cut mortise Correct answer.
  2. Mortises cannot be marked accurately
  3. The tenon must be glued before the mortise is cut
  4. Tenons always shrink more than mortises

Explanation

Fitting the tenon to the finished mortise allows fine adjustment by paring the cheeks, whereas enlarging a mortise accurately is difficult once it is cut. This gives a controlled, tight fit.

Question 40Woodwork

What is the purpose of a vapour-barrier or breather membrane detail behind external timber cladding?

  1. To bond the cladding to the sheathing
  2. To increase the structural strength of the frame
  3. To insulate the cavity thermally
  4. To allow moisture vapour to escape while shedding liquid water Correct answer.

Explanation

A breather membrane is vapour-permeable but water-resistant, so it lets moisture vapour out of the wall while keeping wind-driven rain away from the structure. It is not a structural or bonding component.

Question 41Woodwork

A woodturner is hollowing a end-grain bowl and experiences repeated catches near the rim. Which change is most likely to reduce the problem?

  1. Riding the bevel and taking lighter cuts from the rim inward Correct answer.
  2. Increasing lathe speed to maximum
  3. Using a longer tool overhang
  4. Removing the tool rest for better access

Explanation

Catches occur when the cutting edge digs in unsupported. Maintaining bevel contact controls the depth of cut, and light cuts reduce the leverage available to a catch.

Question 42Woodwork

Which property of a timber species makes it suitable for steam bending chair backs?

  1. High density and hardness
  2. Large shrinkage on drying
  3. High natural oil content
  4. High flexibility and toughness when steamed Correct answer.

Explanation

Steam bending relies on the wood becoming plastic when hot and wet, so species with good flexibility and toughness bend without fracturing. Ash and beech are traditional choices for this reason.

Question 43Woodwork

A workshop uses a portable circular saw to break down large sheet goods. Which practice best improves the straightness and safety of the cut?

  1. Setting the blade depth to maximum for all cuts
  2. Cutting freehand with the blade guard taped back
  3. Removing the riving knife to reduce friction
  4. Clamping a straight edge as a guide and setting blade depth just over the material thickness Correct answer.

Explanation

A straight-edge guide controls the line of cut, and setting the blade just proud of the workpiece reduces the exposed blade and gives a cleaner cut. Guards and safety devices must remain functional.

Question 44Woodwork

Why should a solvent-based wood stain be stirred thoroughly before use?

  1. Stirring activates a chemical hardener
  2. Pigment settles to the bottom, so stirring gives consistent colour Correct answer.
  3. Stirring raises the temperature for faster drying
  4. Stirring removes the solvent

Explanation

Pigmented stains contain suspended pigment that settles during storage. Without thorough stirring, the first coat is thin and the last is overly dark and muddy.

Question 45Woodwork

A customer wants a durable, natural-looking finish on an oak dining table that may be wiped with a damp cloth. Which finish is most appropriate?

  1. A hard-wearing polyurethane or catalysed lacquer Correct answer.
  2. A wax polish only
  3. A shellac French polish
  4. Raw linseed oil only

Explanation

Polyurethane and catalysed lacquer form tough, water-resistant films suitable for a working tabletop. Oil-only and wax-only finishes offer little resistance to water and wear, and shellac is sensitive to water and alcohol.

Question 46Woodwork

A board is planed with a plane iron set with too much camber (curve) across its width. What effect will this have on the surface?

  1. The plane will not cut at all
  2. The plane will tear out along the grain
  3. The plane will leave a series of scalloped hollows across the board Correct answer.
  4. The plane will cut only on one side of the blade

Explanation

A strongly cambered iron concentrates the cut in the centre of the blade and feathers out at the edges, producing overlapping scallops. A slight camber is useful for roughing, but too much prevents a flat surface.

Question 47Woodwork

When laminating curved chair laminates, why are the laminations arranged with alternating grain orientation and glued in a former?

  1. Alternating grain balances stresses and the former holds the curve while the glue cures Correct answer.
  2. The former prevents the glue from drying out
  3. Alternating grain reduces the amount of glue needed
  4. Alternating grain makes the glue cure faster

Explanation

Alternating the grain direction balances the tendency of each lamina to cup and reduces springback, while the former holds the assembly to the required curve until the adhesive has fully cured.

Question 48Woodwork

A cabinet door made from solid timber has developed a gap at one corner where a mitre joint has opened. Which explanation is most consistent with the failure?

  1. The door was hung upside down
  2. The hinge screws were too long
  3. Differential movement of the two members caused by grain direction and humidity change Correct answer.
  4. The finish was applied too thinly

Explanation

In a mitre joint the two members meet with grain running in different directions, so seasonal movement acts across the joint and can open it. A spline or key reduces this risk by adding mechanical restraint.

Question 49Woodwork

A workshop is planning to machine a batch of tenons on a spindle moulder. Which control measure is most important for preventing kickback?

  1. Using a power feeder with a correctly set Shaw guard and short feed fences Correct answer.
  2. Increasing the cutter block speed beyond the manufacturer's rating
  3. Feeding the work from the outfeed side
  4. Removing the guard to see the cut more clearly

Explanation

Kickback occurs when the cutter grabs the work, so the workpiece must be held and fed mechanically against the rotation with guards and short fences supporting it close to the cut. Guards must never be removed to improve visibility.

Question 50Woodwork

A veneered panel shows a small blister after pressing. Which repair approach is most appropriate for a veneer blister that has not torn?

  1. Apply wax and buff the blister flat
  2. Sand the blister down until it is level
  3. Soak the area with water and allow it to swell
  4. Slit along the grain, inject adhesive and press flat with a heated caul Correct answer.

Explanation

An intact blister can be slit along the grain so the veneer can be laid flat, then adhesive is injected and the area is clamped or pressed with heat until cured. Sanding through would destroy the veneer.
