Mr. Ambrose's version of the Lanchester type:
A Japanese student's work: Well done, Nobuyuki Umetani! (found
interesting thing on this work is that a
working model was generated by a
"rapid prototyping" process, i.e.built
fully automatically by a laser machine
from liquid resin.
Times do change! Rapid Prototyping is becoming main-stream,
and can be tackled by enterprising hobbyists already.
Instead of blueprints STL files are published, and if You like a design
just "print it" in some solid material.
In October 2011 I was offered a Chariot design, available as "open source" for pick-up at a site called Thingiverse. Not having such a machine (yet?) I was lucky enough to talk the designer into printing me a set in Canada for little money. Tires from the Czech Republic and some scrap metal from my German shop made this model a highlight of my collection.
Well done, Brad!
Needing a model NOW but the 3D printer is still way down on
the wish list?
No worries, Don Clucas from down under
may be able to help You.
