Building a Model Wall
4.2a
1. Stack 21 craft sticks one on top of the other. Wrap a rubber band around the center to hold them together. Using
a 3/16 in. bit, carefully drill a hole through all the sticks at once, 1 cm from the end of the stack. Drill slowly to
avoid cracking the wood.
2. Select the thinner of the two large pieces of wood (45 cm x 6 cm). Drill a 3/16 in. hole 1 cm from one end and 1
cm from the edge. Measure the distance between the holes drilled in the craft sticks and space three more 3/16 in.
holes at that distance 1 cm from the edge so that a total of four holes are drilled (see illustration).
3. Use the small wood screws to mount this piece of wood on the base (the 2 x 6), fastening at the bottom and in
the center. Leave the pre-drilled holes sticking up far enough above the top to accept the drilled craft sticks.
4. Using the bolts, washers, and nuts, assemble the craft sticks to build a model wall.
5. Experiment with tightening bolts and washers until they are just tight enough for the wall to stand on its own.
