Sample Practice Questions

Try these 10 sample questions from the Cabinetmaker Red Seal Examination practice bank. Each includes the answer and explanation. Continue with the interactive practice above to review the full question set.

1. 1A cabinetmaker selects an air-purifying respirator cartridge containing a sorbent. Which airborne contaminant is this cartridge designed to remove?

   1. A.Dust from sanding wood
   2. B.Mist from spraying lacquer
   3. C.Dust from mixing pigment
   4. D.Vapour from coating solventCorrect answer: D

   Explanation: CCOHS states that some air-purifying respirators work by "adsorbing gases or vapours on a sorbent". Solvent vapour is a vapour; the wood dust, lacquer mist, and pigment dust are particulates and require particle filtration.

2. 2A cabinetmaker adjusts a table saw's blade height. Which kerf-separating device is attached to the arbor assembly and moves up and down with the blade?

   1. A.Fixed splitter
   2. B.Riving knifeCorrect answer: B
   3. C.Anti-kickback pawls
   4. D.Blade guard hood

   Explanation: The CPSC staff report describes a riving knife that "attaches to the arbor assembly so that it raises and lowers with the blade". A fixed splitter does not move with the arbor; the pawls resist backward movement of stock, and the hood shields the blade.

3. 3A cabinetmaker bends a steamed solid-wood component around a form using a metal strap with end fittings on the outside of the curve. What stress does the strap chiefly carry that would otherwise develop in that outer portion of the wood?

   1. A.Longitudinal tensile stressCorrect answer: A
   2. B.Longitudinal compressive stress
   3. C.Transverse bearing stress
   4. D.Transverse shear stress

   Explanation: The Forest Service explains, "The tensile stress that would normally develop in the outer side of the piece of wood during bending is borne by the metal strap." The strap and end fittings instead promote compression within the wood; the described function is not to carry transverse bearing or shear stress.

4. 4For a veneered cabinet panel, the maker reverses every other consecutive leaf before joining their long edges, producing mirrored grain at each joint. Which adjacent-leaf matching method is being used?

   1. A.Slip matching
   2. B.Random matching
   3. C.Book matchingCorrect answer: C
   4. D.End matching

   Explanation: The Architectural Woodwork Standards says of book matching, "Every other piece of veneer is turned over so adjacent pieces (leaves) are opened like the pages of a book." Slip matching keeps the same face sides exposed, random matching varies order and orientation, and end matching extends the apparent length by joining leaf ends.

5. 5While assembling a single-panel cabinet door, a maker refers to the full-height vertical outer member on the hinged side of the door frame. What is that member called?

   1. A.Mullion
   2. B.StileCorrect answer: B
   3. C.Rail
   4. D.Muntin

   Explanation: The Architectural Woodwork Standards states that "The vertical members of the frame are called stiles, while the horizontal members are known as rails." A mullion divides panels, and a muntin is a smaller bar in a glazed opening; the question identifies the outer frame member.

6. 6A cabinetmaker stains equally prepared surfaces from the same piece of solid wood. Which surface will typically absorb substantially more stain because of its porosity?

   1. A.Radial side-grain face
   2. B.Tangential side-grain face
   3. C.Oblique side-grain face
   4. D.End-grain cross-sectionCorrect answer: D

   Explanation: The Forest Service states that "The end grain of wood is commonly 100 times more porous than the side of a piece of wood, so it will absorb much more stain or other finish." The radial, tangential and oblique faces in the options are side-grain surfaces.

7. 7An installer positions a postformed laminate countertop with its backsplash near an uneven wall. The scribing compass will trace the wall profile onto the backsplash. How should the compass opening be set for the first pass?

   1. A.To the widest wall-to-backsplash gapCorrect answer: A
   2. B.To the narrowest wall-to-backsplash gap
   3. C.To half the widest wall-to-backsplash gap
   4. D.To twice the widest wall-to-backsplash gap

   Explanation: The countertop fabricator's guide directs the installer to "set the points of a compass at the widest gap between the backsplash and wall". The narrower, halved, and doubled settings do not match the described method.

8. 8A cabinetmaker lays out a stair with a finished floor-to-floor rise of 1,440 mm and eight equal risers. What is the height of each finished riser, rounded to the nearest millimetre?

   1. A.160 mm
   2. B.180 mmCorrect answer: B
   3. C.206 mm
   4. D.240 mm

   Explanation: The BC trades learning module says to "divide the total rise by this number to get the actual rise". The calculation is 1,440 mm ÷ 8 = 180 mm. The other results come from dividing by nine, seven, and six risers respectively; 1,440 ÷ 7 rounds to 206 mm.

9. 9A cabinetmaker examines an escape-only air-purifying respirator that fits into the mouth and uses a clip to close the nostrils. What form of respirator is this?

   1. A.Quarter-mask respirator
   2. B.Mouth-bit respiratorCorrect answer: B
   3. C.Half-facepiece respirator
   4. D.Full-facepiece respirator

   Explanation: CCOHS describes a "Mouth bit respirator" as one that "fits in the mouth and comes with a nose clip to hold nostrils closed - for escape purposes only". The other forms cover the nose and mouth, extend below the chin, or cover the full face, respectively.

10. 10One face of a solid-wood board has been jointed flat. Which machine is used to dress the opposite face to a consistent thickness parallel to that reference face?

    1. A.Thickness planerCorrect answer: A
    2. B.Surface jointer
    3. C.Spindle shaper
    4. D.Oscillating spindle sander

    Explanation: Syracuse's woodshop guide states that "a Thickness Planer is used to derive a specific thickness with the faces of the boards being parallel to each other". The jointer prepares a reference face; a spindle shaper or spindle sander is used to shape or smooth profiles rather than automatically thicknessing the opposite face.
