Steps

  1. Lay one 1200mm beam horizontally in your workspace. Add a 600mm beam perpendicular at each end, forming a staple shape. (see image 5 for final shape reference)
  2. Using 8 total washers, slide 2 at a time into each rail at the corner, approximating the hole pattern on the side plates. (image 2)
  3. Using a screwdriver to position the T-nuts, add an M8x16 Bolt and washer through the side plate into each T nut. (images 3 and 4)
  4. Secure with a socket wrench. Repeat on the other side of the 1200mm beam.

4x Corner Plates

32x T nuts

32x Washers

32x M8x16mm Bolts

Steps

  1. Stand one leg unit upward, so you can see down the 1200mm section. Slide 4 T-nuts total (2 in each rail) up to the corner joint. (image 2)
  2. Attach the side plate (image 3) using 4 M8x16 Bolts with 4 washers.
    1. NOTE: the 45° side should face the "bottom" of the eventual table.
  3. Repeat on the remaining three 600mm legs.
    1. NOTE: ensure that each corner plates mirror each other across the 1200mm beam axis. They should be facing the same direction.
  4. Slide 8 total T-nuts into a 520mm beam. They should be split in half, 4 at one end, and 4 at the other. (Image 4)
  5. Combine the two "staple" sections by adding the 520mm beam (pre-loaded with T-nuts) using the same M8x16mm, washer combination as before. (image 5)
  6. Repeat on the other side. (image 6)

You should now have a very solid table base!
