Making the Pentafleur lamp

The main lamp body has 62 faces: 12 pentagons, 20 triangles, and 30 squares. If you look carefully, you'll see that three additional polyhedral shapes are revealed by the pattern of the kumiko (the latticework frames to which the paper is glued):

1) The icosahedron, which is made up of 20 triangles.

2) The dodecahedron, which is made up of 12 pentagons.

3) And the Catalan deltoidal hexecontahedron, which is the dual of the rhombicosidodecahedron and is made up of 60 kite-shaped faces. (Each vertex of the dual touches a face of the original.)

Ingredients:

285 pieces of maple

705 pieces of mahogany

705 dowels

296 pieces of washi (shoji paper)

470 neodymium disc magnets

77 wood screws

23 lamp hardware parts

1 dozen audiobooks

4 pinches of patience

2 jiggers of stubbornness

1 dash of insanity

Recipe:

1) Calculate the dihedral and miter angles

2) Build cutting, drilling, and gluing jigs

3) Plane maple planks to width

4) Rip maple with table saw and bandsaw (for the dihedral angles) to create 100' of frame stock, as well as the five lamp stand legs

5) Rout 100' of rabbets, 55' of round-overs, and one 5' groove (to run the cord in one leg)

6) Sand with power palm sander

7) Make 2,000+ cuts with power and hand miter saws

8) Make fine angle adjustments with a spindle sander and fine length adjustments with a disc sander

9) Glue up 1,000+ joints using clamps and jigs

10) Drill 1,200+ holes using jigs and freehand

11) Glue in 1,100+ dowels and magnets

12) Sand with a drum sander and by hand

13) Add a coat of finish

14) Add two more coats of finish, hand sanding between each

15) Assemble

16) Plug in

17) Light!
