Step 1: Making the Parts


  1. Timber: Totara - A New Zealand hard wood or what ever you have around!
  2. Dimensions: 40mm x 140mm x approximately 2000mm
  3. Gorilla grip glue
  4. 24 10mm dowels
  5. Ruler
  6. Pencil
  7. Extra wood for when you put in the vice
  8. 10mm spade drill bit
  9. Dowel markers or small nails
  10. Clamps
  11. Safety gear
  12. A drop saw
  13. Cordless drill
  14. A protractor or 30 degree angle

Cutting the wood

Legs 40mm x 140mm x 310mm (3 of these)

  1. To create a leg that narrows, mark 50mm down one side and 50mm across on the opposite corner and rule a line between the two points. Cut off the wedge.
  2. Down the outer length of the leg cut a 30 degree angle from a marked halfway point at the top with the drop saw.

Seat: 40mm x 140mm x 215mm cut on a 30 degree angle (3 of these)

  1. Using the protractor mark a 30 degree angle at the end of the wood (or set the drop saw to 30 degrees.
  2. Measure and cut one piece of the seat.
  3. Place that piece on the remaining length and mark the next piece to cut.

Step 2: Assembling the Seat

Sorry, I forgot to get many photos of this bit

  1. Assemble your three seat pieces together to check they fit more or less. The shape can be trimmed if necessary later on.
  2. With a pencil, mark out evenly between the pieces where the dowels will be between the seat pieces. I used 4 dowels per joint e.g. 12 dowels for the seat.
  3. Drill dowel holes and test the fit.
  4. Glue and clamp. Try to get the joints as tight as possible.
  5. If the outer opposite edges are not parallel, then trim to shape. Ensure the joints end at the points.
  6. Sand the seat.

Step 3: Fitting the Legs to the Seat

  1. Number each leg against the seat.
  2. Align the edges and trace the edge.
  3. Mark out the dowel holes on the seat. Either use dowel markers or small nails to align the centres. I used 4 dowels per leg joint.
  4. Drill the holes. Use tape on the drill to ensure you don't drill too deep.
  5. Test the holes. Glue and clamp

Step 4: Polyurethane or Oil the Stool

You can sand if necessary.

    Hello - That stool looks very good. I think I will try to make one or two. Quick note, under Materials, number 2 the last dimension is listed as "approximately 2000mm", should that be 200mm? :-)

    My bad - your were giving the material length for the wood - not the dimensions of the seat. Still like the stool. Thank you for the good instructions.

    This is the kind of instructable I come to this site for.

    I think I understand where you used the dowels, but not for the life of me can I figure out how you would use 4 on a 3 part, 3 leg stool. And the comment above about entering it in a contest was right. I would vote the heck out of this one.

    Thanks for the feedback. I have just updated the description.

    There are 4 dowels in each joint of the seat. So the seat has 12 dowels in total.

    The legs also use 4 dowels each. It should be pretty strong.
