Short Summary
Main recommendation: Build a sturdy utility step stool from a single 2x4 using interlocking notched joints, cut with a table saw, dado blades, and 15° bevels. The video shows the full build sequence from rough cutting to finishing, and the finished stool is tested for strength and levelness.
Key Points
- The stool is built entirely from one 2x4, with the top, uprights, and cross braces all cut from that board.
- Interlocking half-lap notch joints are used throughout, which the speaker says make the joints very strong.
- Dado blades in the table saw speed up cutting the half-lap notches; without them, multiple passes with a regular blade work.
- Angles and bevels throughout the project are 15°, with opposing angles on horizontal pieces and parallel angles on uprights.
- A finger hole is drilled in the top to make the stool easier to carry.
Details Worth Noting
- Concrete instructions:
- Trim the rounded edges off the 2x4, then rip it on edge so the width equals the thickness.
- Cut the four upright pieces to length, then cut half-lap notches using the dado stack with the fence set as a stop, which is safe because the cut goes only partway through the board.
- Cut the horizontal pieces at opposing 15° angles, notch one side, flip and notch the opposite side, then cut the small top supports and their half flaps.
- Set the miter gauge to zero and notch the bottom pieces, then glue the two side assemblies together.
- To resaw the board into two pieces, use a feather board to keep it against the fence, run it on edge through the saw, and finish with push sticks. Use a sacrificial board on the fence and shift the fence in small increments until the cut piece fits the notches flush.
- Glue in the cross brace, then cut the top into three equal-length pieces.
- Bevel the two outside top boards at 15°, glue them in place, then cut the center board to fit.
- Drill a finger hole in the top for carrying.
- Apply two coats of Danish oil for protection.
- The speaker warns that ripping with the fence as a stop should never be done when cutting all the way through, because it can pinch the piece and cause kickback.
- The video's camera failed mid-shot during the resawing step, so the speaker recreated that process on camera.
Bottom Line
A single 2x4 and a table saw are enough to make a strong, portable step stool with interlocking joints, and the video gives a clear, repeatable sequence for doing it.
