Step 1.

Steps 1-3

1. Assmeble supports. Put together six bench supports, using 2x4 pieces and screws. The faces of these will show, so make sure the ends of the three pieces are evenly cut and flush.

Step 2.

2. Cut the inside pieces. Cut six pieces of 2x4 to be used as the seat pieces closest to the tree. The measurement of the longest side will equal the diameter of your tree. (If you have a fast-growing tree, make them 2 inches longer.) With two helpers, hold up all six pieces around the tree to make sure they are the right size.

Step 3.

3. Start the layout. On a large, flat surface, lay out the first bench section (half the circle), using four seat support sand three of the bench pieces that you have just cut. Adjust them so that all angles are equal. Do not assemble yet.
