| The oldest published design I found yet was from Mr. M.J. Oliver, printed in The Meccano Magazine, Jan 1957. It is based on the description given two years earlier by Mr. Cousins | |
 |
Twenty (!) years later, in 1977, Mr. Terry Morris revived the previous design in
another article in The Meccano Magazine.
Apart from more stylish wheels this model adds little new insight. |
 |
| But it sparked new interest, e.g. the (undated) model from Ashok Banerjee. |  |
| Even today new models are built using the classic screw&bolt parts, like this wonderful specimen of Hans-Gerd Finke. |  |
|
|
| If you have the gears, it may look like this fine model, proposed by C S Soh from Singapore |  |
 |
More LEGO bricks and a novel design by Dr. Adam Eppendahl |
| And finally ths LEGO contraption, build by Philipp Hörler. Basic design seems to be simular to "my" ODTS II |
 |
 |
Did I say "finally"? Some guy in Taiwan (sorry, I couldn't decode his Chinese homepage) built this LEGO model - aesthetically most pleasing! I stole his instruction sheets, see here, here and here for the benefit of other "westerners". |
| And last not least another LEGO contraption.
This one was proposed by Prof. Dr. Liebscher (Potsdam) for the hands-on
study
of some geometic concepts. It should be noted that some parts must be
machined. |

This very pretty acrylic model of the Lanchester type was
build by Richard Egge, to be contacted over this site at
http://www.geocities.com/~rrice2.
He has a full set of drawings for it as well !
|
| Too modern ? What about this interpretation (Richard Egge again) |  |
 |
Or the ORIGINAL WOODEN TYPE (Richard Egge, who else...) |
| Which, by the way, is getting copied more and more. This fine specimen is by Frank Petersohn in Canada |
 |
 |
They are
built by students
(Taiwan in the 80ies)... |
 |
| And this beauty in brass and painted wood was
done
by Cyril Collins of Fredericton, also Canada |
 |
 |
The Ultimate Beauty? Made by Geoffrey
Haberman, Canada. If you wish to congratulate him, his emal is memyselfandall@sympatico.ca |

This interesting model was realized by Luc
Macot, teacher at the Collége de Bois-de-Boulogne. See my "translation" of his (no longer available)
homepage. |
 |
These two models to Prof. Nakata's design were found at
www.suelab.nuem.nagoya~u.ac.jp/~suematsu/ (click on the pictures for enlargement) |
 |
| And now at last You can buy Your ready made model - at least
if You reside in Japan... (picture taken from Mechanical Engineering Research Laboratory, Hitachi Ltd.) |
 |
 |
In the Exploratorium, the science museum of San Francisco,
this ride on model is to be seen and tried. Perhaps somebody can send
my a
detailed shot of the gear mechanism? (picture taken from the Exhibits for Sale section (!)) |
 |
Another
great concept: Planetary Gears for the differential! For some theory
look here |
 |
 |
This
concept is not so great: Due to the limited travel of the nut on the
screw rod the
pointer will work only for a few turns. But the idea as such is
brilliant! The theory is also covered in here |
