Herbert (moderator at the German paper modellers forum KARTONBAU.de) downscaled WAP to 50%. He posted three movies and some picture of his work to the German forum. The result is terrific! Consider that Herbert built a lot of tiny rivets to add 3D effects to some parts (like the gears, for example)… Here, I have merged the three movies and posted some nice Herbert’s pictures. Take a look and enjoy Herbert’s amazing work!
In 1901 Joseph Fisher, a Jesuit historian who was conducting research in in the library of Prince Johannes zu Waldburg- Wolfegg in Wolfegg Castle in Württemberg, Germany, discovered the famous large Waldseemueller’s map called Universalis Cosmographia(1507), as part of the Cosmographiae introductio by the German cartographer Martin Waldseemueller (1470–1520). This was the beginning of an intricate and exciting story where one of the protagonists was a small print depicting twelve gores: the first published ready-to-build world globe with, for the first time, the “New World” surrounded by water. And, for the first time, the name America appeared on Earth.
From Wikipedia: Five copies of the globe gores are extant. The first to be rediscovered was found in 1871 and is now in the James Ford Bell Library of the University of Minnesota. Another copy was found inside a Ptolemy atlas and is in the Bavarian State Library in Munich. A third copy was discovered in 1992 bound into an edition of Aristotle in the Stadtbücherei Offenburg, a public library in Germany. A fourth copy came to light in 2003 when its European owner read a newspaper article about the Waldseemüller map. It was sold at auction to Charles Frodsham & Co. for $1,002,267, a world record price for a single sheet map. In July 2012, a statement was released from Ludwig Maximilian University of Munich that a fifth copy of the gores had been found in the LMU Library’s collection which is somewhat different from the other copies, perhaps because of a later date of printing. LMU Library has made an electronic version of their copy of the map available online.
Waldseemueller’s group of cartographers derived the word “America” from the name of Italian explorer Amerigo Vespucci, who was the first to argue that the land mass discovered by Christopher Columbus in 1492 was a new continent, and not part of Asia. Waldseemueller and his fellow scholars used an account of Vespucci’s voyages to draw their new maps. The real merit of Vespucci in the exploration of the New World is still subject of debate, making the story of the Cosmographiae introductio, the large map and the small globe even more fascinating.
You can find a lot of information on Wikipedia, of course. If you are really interested, I suggest to read Toby Lester’s The Fourth Part of the Globe (Free Press, 2009).
Note: The twelve gores I used for this globe design were adapted from the high-res. file (1509 edition) freely downloadable at the Library of Congress website.
Visit the David Rumsey Map Collection website to admire and download Pardies’ star and constellation maps. Another great website with a lot of information about Pardies’ masterpiece is Atlas Coelestis (sorry, mostly in Italian…).
If you have already downloaded the Globe project (before Dec. 3), but you are not satisfied by the final result because Pole holes are not well defined, download the Pole Caps for improving your model.
Stay tuned! Christmas Ball version of Pardies Celestial Globe in progress…
The Mechanism. WAP is a paper automaton whose main mechanism is Redtenbacher`s variation of the Cartwright straight-line mechanism, a twin gear driving a common slider crank. If the two gears have different but almost equal number of teeth, the up and down motion of the bar is then an addition and subtraction of two sinusoidal functions. The straight line generation, determined by the vertical motion of the bar, was a very important problem in the early history of mechanics. In WAP, the “random” motion of the unlucky airplane is generated at the center of the beam, that is free to spin. At that point, the two sinusoidal movements originate the oscillation that, together with the up and down motion of the bar, results in the air-pocket-like shaking up.
Ferdinand Redtenbacher (1809-1863).The transformation of mechanical technology from a mainly workshop-based profession into an engineering science, particularly in the area of design of machines and mechanisms, is closely related with the name of Ferdinand Redtenbacher. He was of eminent historical importance for the evolution of mechanical engineering to a technical science in the nineteenth century. Redtenbacher’s role as the originator of mechanical engineering as a science in Germany is fundamental and of general interest since the introduction of science into engineering is a “sine qua none” for the development of a powerful high tech industry. As a professor and the director of the Polytechnic School in Karlsruhe, Germany – today the University of Karlsruhe (TH) –, Redtenbacher’s influence therefore helped establish the German manufacturing systems engineering even today. (from Wauer, J., Mauersberger, K., Moon, F. C., 2010.

Years ago, paper modellers community was very excited by the so called hako designs, small paper figures mainly made of boxy parts assembled together. There was a bloom of paper hakos, some of them truly exquisite. As many others, I designed some hako models, too.
Petrus Plancius (Pieter Platevoet, 1552-1622) was a famous Flemish cartographer. He included new constellations in the austral celestial emisphere. In 1612, he drew 12 gores for a 14.5 cm diameter celestial globe, with eight new constellations inspired to the Bible. For the present model, the original gores published in 1649, were downloaded from the Bibliothèque nationale de France website. The colours of the original file were digitally converted in the “nocturnal” version here presented.
Petrus Plancius (Pieter Platevoet, 1552-1622) fu un famoso cartografo fiammingo. Autore di numerosi globi celesti, egli introdusse nuove costellazioni nell’emisfero australe. Nel 1612 disegnò 12 fusi per un piccolo globo celeste del diametro di 14.5 cm, in cui compaiono otto nuove costellazioni ispirate alla Bibbia. Per questo modello, i fusi originali, pubblicati nel 1649, sono quelli scaricabili dal sito web della Bibliothèque nationale de France. Con un semplice processo di ridefinizione della gamma cromatica, i fusi sono stati trasformati nella versione “notturna” qui proposta.
