MAKOTOKOMA (SPINNING YOP)

Written by sidlook. Posted in Sonobe Varitions

hYou might think a spinning top to be a trivial achievement in origami, but this is not the case. Making a device that’s rigid enough to be rapidly spun and has the appropriate weight distribution is a real challenge. Makoto Yamaguchi is one of the most experienced origami creators in Japan. He formed the Japanese Origami Academic Society (JOAS), a group responsible for much of the complex origami that has emerged from Japan in recent years. In this design you use three simple elements to combine into the top.

Base

1. Start with a square, white side upwards, and crease both diagonals.

2. Turn the paper over and book-fold in half twice.

3. Turn back over and fold all four corners to the centre.

4. This is the starting point for all the sections of the top.

BaseOuter section 1. Fold all four corners to the centre. 2. Fold the corners back out to the midpoints of the outer edges. 3. The section complete. Outer BaseMiddle section 1. Turn the base over. 2. Fold the corners to the centre. 3. This is the result. Turn the paper over. 4. Fold the corners to the centre once more. 5. This is the result. Turn the paper over. 6. Fold the corners back out to the midpoints of the outer edges. 7. The section complete. MIDDLEInner section 1. Fold four corners to the centre. 2. This is the result. Turn the paper over. 3. Fold four corners to the centre. You should be good at this by now! 4. This is an enlarged view. Book-fold in half both ways. 5. Turn the paper over and crease both diagonals. 6. Collapse the paper into a water-bomb base (Chapter 3 describes the waterbomb base). 7. The section complete. LNNERAssembly 1. Take the outer section and unfold the outer flaps. 2. Place the middle section in the centre of the paper. 3. Refold the flaps, tucking them under the upper corners. 4. Slightly open a pocket on each side. 5. Slide the inner section into the pockets. 6. Take the model for a spin! adsembly
