Making a Rubik's cube from scratch is not an easy task. They can be made from paper, plastic or dice but they are all complicated to make. The reason they are difficult to make is because of the core. The core is made from molded plastic or metal. The connecting pieces on the cubes are also difficult to make. The easiest way to make a Rubik's cube is to use the core and connecting pieces from an old cube.
Things You'll Need
- 23 wooden cubes (3/4 inch)
- F II speedcube
- Colored stickers
- 11/32 and 15/32 drill bits
- Sharp X-Acto knife or small saw
Take apart the speedcube. Start with the top row middle cubie. Be careful when removing the first piece because you do not want to break any of the cubies. Tear apart each row. When the entire cube is apart, you will have all the cubies and the core with six center cubies attached to it.
Draw a line from corner to corner on each cubie. Draw the lines on any of the non-stickered sides. Draw a second line on each cube about 1/8 of an inch inside the first line.
Cut each cubie in half along the second line. Use a very sharp X-Acto knife or a small saw. If necessary, hold the cubie's in place with small clamps. Throw away the bigger pieces and keep the smaller pieces with the connecting parts.
Cut each wooden cube the same as in step three. Draw a line from corner to corner. Draw a second line 1/8 of an inch inside. Cut along the second line with a small saw. Sand the rough edges with sandpaper. Throw away the small pieces of the cut cubes and keep the larger pieces.
Glue one piece of wooden cube to one plastic piece. You will have an entire cubie, except that it is half wood and half plastic. Glue the rest of the pieces the same way until you have all the cubies. Let them dry according to the instructions on the epoxy container.
Remove the center cubies from the core. They can be broken off, but be careful not to break the core. The cubies can also be cut off with the saw or X-Acto knife. There is a screw inside, so try to cut as close to the cubie as possible. When the cubies are removed, you will have a four pointed core with the screws inside the ends.
Make the center cubies. Mark center on the last three wooden cubes by drawing an X from corner to corner. Center is where the X meets in the middle. Drill a hole with the 11/32 drill bit all the way through the center of the cubes.
Turn the cubes so the holes are horizontal and mark center again. Turn the cubes so that the hole is perpendicular to your body and cut the cubes in half with the saw. You will have two smaller cubes with holes in the middle. Sand the rough edges. When all are cut the same way, you will have six center cubies.
Drill a hole halfway through each center cubie with the 15/32 drill bit. When you look inside the drilled cubies, you will see a larger hole and then a smaller one.
Attach the center cubies to the core. Remove the screws from the core and place the cubies on the core. The smaller hole goes over the core. Place the screw through the larger hole and screw it tightly in place. The smaller hole in the cubie holds the cubie in place on the core. When all center cubies are attached, the core is finished.
Assemble the rest of the Rubik's cube so that it is solved when back together. Start with the edge pieces. This can be tricky because they tend to fall off. Next do the corner pieces and then the layers. The last piece snaps in place.
Place the colored stickers on the cubies. The stickers will cover the holes made for the screws.
