Gather and prepare your workspace

Clear a flat work surface and gather all your materials and tools. Lay out your wood boards and inspect them for any defects or warping. Set up your saw station in a well-ventilated area.

Measure and mark the side panels

Take your 1x12 pine boards and measure two identical side panels, each 24 inches tall. Mark the stepped profile: bottom step at 8 inches high, middle step at 16 inches high, with each step being 10 inches deep. Use a straightedge to draw clean lines connecting these points in a stair-step pattern.

Cut the side panels

Carefully cut along your marked lines using a jigsaw or handsaw. Cut both side panels identically so your stool sits level. Sand the cut edges smooth with 120-grit sandpaper to remove any splinters.

Cut the step treads

Measure and cut three step treads from your 1x10 pine board, each 18 inches long. These will form the horizontal surfaces you step on. Sand all surfaces and edges smooth.

Mark drilling points on side panels

On the inside face of each side panel, mark where the treads will attach. For each step location, mark two pilot hole positions about 1 inch from the front and back edges, centered on where the tread will sit. This prevents wood splitting when you screw the pieces together.

Drill pilot holes

Using a drill bit slightly smaller than your wood screws (about 1/8 inch), drill pilot holes at all marked points on both side panels. Drill straight through the side panels where the treads will attach.

Apply wood glue to first tread

Apply a thin, even line of wood glue along the edge of the bottom tread where it will contact the side panel. Don't use too much or it will squeeze out when you clamp it.

Attach the bottom tread to first side panel

Position the bottom tread against one side panel, aligning it carefully with your marked step location. Drive two 1.5-inch wood screws through the pilot holes to secure it firmly. Wipe away any excess glue immediately with a damp cloth.

Attach remaining treads to first side panel

Repeat the gluing and screwing process for the middle and top treads, working your way up. Make sure each tread is flush with the front edge of the side panel and properly aligned.

Attach the second side panel

Apply wood glue to the exposed edges of all three treads. Carefully position the second side panel onto the treads, aligning everything properly. Drive screws through the pilot holes in this side panel into each tread. Use clamps if needed to hold everything in place while screwing.

Let glue dry and check stability

Allow the wood glue to dry completely according to the bottle instructions (usually 1-2 hours minimum). Check that all screws are tight and the stool sits flat on the ground without wobbling. If it rocks, you may need to sand one leg slightly shorter.

Final sanding

Sand the entire stool with 120-grit sandpaper, then finish with 220-grit for a smooth surface. Pay special attention to edges and corners where hands and feet will touch. Wipe away all dust with a tack cloth or damp rag.

Apply finish

Choose your finish: paint, stain, or clear polyurethane. Apply according to product directions, usually 2-3 thin coats with drying time between each. If painting, consider a primer coat first. Allow full curing time (24-48 hours) before using the stool.
