Detailed Instructions:
Follow these steps carefully to ensure a sturdy and well-constructed block stool.
Step 1: Preparing the Large Leg Pieces
Begin by shaping the larger leg pieces. This involves making angled cuts to create the distinctive block stool design.
- Take each of the four 7″ x 17 1/4″ boards.
- Measure 6″ down on one side.
- On the opposite end, measure 3″ over.
- Mark a line connecting these two points.
- Carefully cut along the marked line using a jigsaw or circular saw. This creates the angled edge.
- Repeat this process for all four large leg pieces.
- Drill pocket holes on the inside face of two of the leg pieces. This will be used to connect the legs.
- Apply wood glue to the edges that will be joined.
- Use 1 1/4″ pocket hole screws to join two 7″ boards together, forming two larger leg assemblies.
- Clamp until the glue dries.

Step 2: Preparing the Small Leg Pieces
Next, prepare the smaller leg pieces, which will complement the larger ones to form the stool’s base.
- Take each of the four 6 1/4″ x 17 1/4″ boards.
- Measure 6″ down on one side.
- On the opposite end, measure 2 1/4″ over.
- Mark a line connecting these two points.
- Cut along the marked line using a jigsaw or circular saw, creating the angled edge.
- Repeat this process for all four small leg pieces.
- Drill pocket holes on the inside face of two of the leg pieces, focusing on the edges that will be joined.
- Also, drill additional pocket holes that will be used to assemble the stool and attach the top later.
- Apply wood glue to the edges of the small leg pieces.
- Use 1 1/4″ pocket hole screws to join two 6 1/4″ boards together, forming two smaller leg assemblies.
- Clamp until the glue dries.

Step 3: Constructing the Stool Top
Now, let’s assemble the stool top. This will provide a comfortable and stable seating surface.
- Take the two 7″ x 14″ pieces.
- Drill pocket holes in one of the 14″ pieces along the edge that will be joined.
- Apply wood glue to the edges of both pieces.
- Use 1 1/4″ pocket hole screws to join the two pieces together, creating the stool top.
- Clamp until the glue dries.

Step 4: Assembling the Stool Base
With the leg pieces and top prepared, it’s time to assemble the stool base and attach the top.
- Assemble the base pieces by connecting the large and small leg assemblies.
- You can use 1 1/4″ pocket screws on the inside for a cleaner look or 1 1/2″ brad nails for a quicker assembly.
- Ensure the corners are aligned properly for stability.
- Once the base is assembled, attach the top to the base using 1 1/4″ pocket hole screws or 1 1/2″ nails.
- Make sure the top is centered on the base before securing it.

Step 5: Finishing Touches
The final step involves refining the stool’s appearance and protecting the wood.
- Fill any cracks, blemishes, or screw holes with wood filler and allow it to dry completely.
- Sand the entire stool, starting with a coarser grit sandpaper and finishing with 120-150 grit paper. Sand in the direction of the wood grain for a smooth finish.
- Choose your desired finish: paint, stain, or a clear top coat. Apply the finish according to the manufacturer’s instructions.
- Allow the finish to dry completely before using the stool.
