I've looked through two sources of Meccano information:
the main website: http://www.meccanotoys.com/
and a parts list: http://freenet.edmonton.ab.ca/meccano/mecparti.html

My opinion now, after being more educated on what Meccano has to offer, is
that Lego is probably best, depending on how you intend to use it.

If a building system is needed to quickly and easly demonstrate mechanical
and structural concepts, then Lego is surely the best choice:
1. It is easy to connect and dissasemble.
2. Its basic members (i.e. Technic beam) are relatively strong by their
given shape (compared to a skinny piece of perforated metal flatbar, which
lacks significant lateral strength and therefore must be strenthened).
3. It offers a wide range of elements to realistically model many
mechanical, electrical, and structural systems.
4. It is readily avaible and even has an educational division, Dacta.

If a building system is needed to be very realistic, then I think a
"building system" must be built from scratch. Stock up on small sections of
flatbar, angles, channels, I-beams, tubes, and plate as well as bolts and
welding equipment. This home-build "system" is simply a small version of the
real thing and demonstrates exactly what an engineer will face in the real
world. And don't forget all the tools required to accomplish such construction.

I think that Meccanno fits in somewhere between the home-built solution and
Lego parts. It's not exactly the real thing, but it's not as easy to use as
Lego is.

Think of this: you're given a simple assignment to construct a model truss
to demonstrate how a truss works. Do you want to spend days cutting,
drilling, and shaping steel? Or do you want to spend an afternoon, in your
clean room, putting together a few plastic pieces with no tools required?

"Dear Sir

I would like to take the opportunity to respond to Christopher Ward’s letter
(nCE 28 June) and his comments regarding the relative merits of Meccano and
Lego.  I can only assume that Mr Ward is unaware of the elements available
in Lego’s Technic and Dacta product lines, particularly the Technic beam and
connector pin system which enables large trusses to be built very quickly.

I am a member of the online Lego community Lugnet (www.lugnet.com).  Mr
Ward’s letter has led to some interesting discussions among the world’s Lego
enthusiasts and we would like to offer some examples of the functionality of
Lego.

I am unsure whether Mr Ward was advocating Meccano as a structural or a
mechanical engineering modelling tool so I’ll address the Civils issues
first.  I was taught that there are four main materials used in
construction: Timber, Concrete, Masonry and Steel.  Clearly neither system
would be good for modelling timber construction, concrete is similarly
beyond either.  Lego is far better at masonry because its basic elements are
bricks and I would strongly contend that there is little to choose between
the two as far as modelling steel construction is concerned.  I would add
that steel structures are generally welded or riveted together and the Lego
friction pin system is a better analogue for this than Meccano’s bolts.
Pictures of Lego structures can be found at
www.lugnet.com/~469/projects/archbr (Ross Crawford’s arch truss bridge) and
(further example)

As far as mechanical engineering is concerned Meccano may have had an
advantage prior to the late 1970s but these days Lego has a much wider range
of gears and other mechanical elements than Meccano, including
differentials, shock absorbers, pneumatic pumps and cylinders, gearboxes,
cams and flexible drive shafts.  Examples of models which show good use of
mechanical principles are Jennifer Clark’s trucks and construction machinery
(www.telepresence.strath.ac.uk/jen/lego/) and Dennis Bosman’s mobile cranes:
(www.geocities.com/MotorCity/Highway/2290/bmnr04.html).

Lego also has an educational theme called Dacta, which is only available to
educational establishments (though if anyone is interested it can be bought
at Legoland or by mail order from www.pitsco-legodacta.com).  Dacta includes
solar cells, capacitors and other electronic and mechanical parts along with
teaching guides and other support to use Lego in the classroom.  I do not
believe anything so comprehensive has ever been provided by Meccano.

In an educational environment Lego has a few distinct advantages, firstly
and most importantly that it is quick to put together and take apart and
secondly that it is easier for a child to pick up the idioms necessary for
successful construction. (Professor Fred Martin of MIT has written a useful
guide which explains these:
ftp://cherupakha.media.mit.edu/pub/people/fredm/artoflego.pdf). For these
reasons I feel that Lego is a better educational tool than Meccano.

To summarise I am a Civil Engineer in large measure thanks to Lego and I
cannot allow such a slight to the Toy of the 20th Century to go unchallenged.

Okay. Now I know how FTP works (i.e seamlessly, it wasn't like that in 1994 when I was at University!) As Gael says that is a cool article, just one question. Did the Constructopedia ever go online? I have never seen any reference to it on Lugnet. (...) (23 years ago, 3-Jul-01, to lugnet.technic)
