SCAFFOLDHelping to support and maintain the world of origami

Science and snails abound

The models in this issueseem to all be scienceorinted (spaceships andgeometrics) except the Snail.Geometrics also play a major

role in this months bookreview. Enjoy.

Back Issues

New Books

I found two new books to addto my collection this month.One is old while the other isnew, but both are full of

intriguing models.

HAVE FUN WITH ORIGAMIby Robert Harbin (English)(ISBN 0-900-727-26-8) 51

models by various youngartists and readers of Look-In(junior TVTimes), RobertHarbin himself, and sometraditional models. 1975Independent TelevisionBooks Ltd.

A PLETHORA OFPOLYHEDRA IN ORIGAMI byJohn Montroll (English) (ISBN0-486-42271-2) 27 single-sheet geometric models.2002 Dover ($12.95 US).

Submissions

Scaffold tries to provide aplace for origami designersto show off their designs tothe world folding community.

For that to work, folders haveto send in their diagrams.Scaffold can accept mostelectronic formats, but DXF(generic CAD format) results

in very small file sizes.All models and

diagrams remain the property

of their designers andScaffold will not change oredit diagrams (with theexception of clarifying scans)and will publish all designs

submitted. Crease-folddiagrams are also acceptedand allow for a greaternumber of models per issue(as well as offering a differentstyle of challenge for thereader).

Diagrams can be

submitted electronically bysending e-mail toscaffold1@aol.com . Paperdiagrams can be sent to:

Joshua KoppelPO Box 641374Chicago, IL 60664-1374USA

Submissions shouldbe accompanied by astatement saying that youwish them to appear inScaffold.

Book Review

A PLETHORA OFPOLYHEDRA IN ORIGAMI isthe latest offering from John

Montroll. Unlike his previousbooks, this one contains

absolutely no animalswhatsoever. As the titlesuggests, this volume is

dedicated solely to variousgeometric solids.

The book is divided

into six sections of models(Platonic Solids, Pyramids,Prisms, Based on theOctahedron, Sunken PlatonicSolids, Dodecahedra) and asection of Crease Patternsthat shows how the visiblefaces of the model translate

onto the starting square.The twenty-seven

polyhedra in this book differfrom most other origamipolyhedra. These models areall made from a single squaresheet of paper. While thatdoes not seem impressivewhen talking about cubes andtretrahedra, the sunken

icosahedron is anothermatter all together.Thiose who are

familiar with Mr. MontrollsStar from ANIMAL ORIGAMIFOR THE ENTHUSIAST willsee a similarity in the waythese models areconstructed. Most of thesemodels follow a pattern ofperforming a lot of

precreasing and thencollapsing and locking themodel into its final form.

As we have come to

expect from Mr. Montroll, themodels are clearlydiagramed with easy-to-follow steps. Polyhedralorigami remains a sub-genre

of origami and may not bepopular with all enthusiasts,but for those who like their

geometry solid, I can think ofno other book like this one.

A PLETHORA OF

POLYHEDRA IN ORIGAMI ispublished in English by Dover(ISBN 0-486-42271-2) andsells for $12.95 US. Thisbook should be found in anygood bookstore and manyonline sites.

The Models

Another varied selection thismonth. Animals, space craft,geometrics, and modularsround out this months newmodels.

SnailThis is a new Snail by Jim

Adams. This time Mr. Adamspresents us with a simple, yetrecognizable, snail. The finalmodel offers has providedme with insights into somenew models of my own.

$-StarshipThis is another fine vehicle bycreator Jim Adams. Thismodel, created from a dollar

bill (3X7) is original whilereminiscent of some famouscraft used on television and inmovies. More of Mr.

Adamss creations can befound athttp://members.aol.com/jeadams1.

Skeleton of Octahedron 4This model is the fourthoctahedron skeleton unit that I

created last month. This oneis based on a 1X2 rectangleand has a secure mechanismfor locking the unit closed.

Sonobe 4BThis is a variation of Variation4 (Crater) which can be foundin Vol. 1 Issue 10 athttp://www.origami4you.com/.Like Crater, this unit also

results in a hole at the vertex.

Sonobe 4C1This is a variation of Variation4 (Crater) which can be foundin Vol. 1 Issue 10 athttp://www.origami4you.com/.Like Crater, this unit alsoresults in a hole at the vertex.

Octahedron Skeleton 4 by Joshua Koppel

Begin with twelve (12) 1X2 rectangles.

1. Fold and unfold. 2. Fold short edges to center.

3. Fold opposite corners to center.

4. Pull out hidden point. 5. Fold in half and tuck flapbehind point. 6. Bend corner f laps.

Sonobe Variation 4B by Joshua Koppel

1. Fold and unfold.2. Bisect the angle. 3. Fold edges to line.

4. Fold and unfold. 5. Fold edges to line. 6. Tuck corners under.

7. Fold flaps behind.

This unit results in a hole at the vertex.The angle created in step 2 is theeasiest to duplicate, but far from theonly one. To create other angles, youcan use the Unit Template byMichael Naughton which can befound in Scaffold Vol.1 Issue 10.
