Meccano

Meccano is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Meccano rather than just read about it. In short: Meccano is a British brand of construction set created in 1901 by Frank Hornby in Liverpool, England. The system consists of reusable metal strips, plates, angle girders, wheels, axles and gears, and plastic parts that are connected using nuts and bolts.

Key takeaways

  • Meccano belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Meccano to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Meccano from memory before moving on to harder problems.

Reference excerpt

Meccano is a British brand of construction set created in 1901 by Frank Hornby in Liverpool, England. The system consists of reusable metal strips, plates, angle girders, wheels, axles and gears, and plastic parts that are connected using nuts and bolts. It enables the building of working models and mechanical devices. In 1913, a very similar construction set was introduced in the United States under the brand name Erector. In 1990, Meccano bought the Erector brand and unified its presence on all continents. In 2013, the Meccano brand was acquired by the Canadian toy company Spin Master. Meccano maintained a manufacturing facility in Calais, France, until 2023.

History

First sets

In 1901 Frank Hornby, a clerk from Liverpool, England, invented and patented a new toy called "Mechanics Made Easy" that was based on the principles of mechanical engineering. It was a model construction kit consisting of perforated metal strips, plates and girders, with wheels, pulleys, gears, shaft collars and axles for mechanisms and motion, and nuts and bolts and set screws to connect the pieces. The perforations were at a standard 1⁄2 inch (12.7 mm) spacing, the axles were 8-gauge, and the nuts and bolts used 5/32" BSW threads. The only tools required to assemble models were a screwdriver and spanners (wrenches). It was more than just a toy: it was educational, teaching basic mechanical principles like levers and gearing. The parts for Hornby's new construction kit were initially supplied by outside manufacturers, but as demand began to exceed supply, Hornby set up his own factory in Duke Street, Liverpool. As the construction kits gained in popularity they soon became known as Meccano and went on sale across the world. In September 1907, Hornby registered the Meccano trademark, and in May 1908, he formed Meccano Ltd. To keep pace with demand, a new Meccano factory was built in Binns Road, Liverpool in 1914, which became Meccano Ltd's headquarters for the next 60 years. Hornby also established Meccano factories in France, Spain and Argentina. The word "Meccano" was thought to have been derived from the phrase "Make and Know".

The first construction sets had parts that were rather crudely made: the metal strips and plates had a tinplate finish, were not rounded at the ends and were not very sturdy. But manufacturing methods were improving all the time and by 1907 the quality and appearance had improved considerably: the metal strips were now made of thicker steel with rounded ends and were nickel-plated, while the wheels and gears were machined from brass. The first sets under the new Meccano name were numbered 1 to 6. In 1922 the No. 7 Meccano Outfit was introduced, which was the largest set of its day, and the most sought after because of its model building capabilities and prestige. In 1926, to mark the 25th anniversary of his patent, Hornby introduced "Meccano in Colours" with red and green coloured Meccano pieces. Initially plates were a light red and items like the braced girders were a pea-green. However, the following year strips and girders were painted dark green, the plates Burgundy red, while the wheels and gears remained brass. In 1934, the Meccano pieces changed colour again: the strips and girders became gold while the plates were changed to blue with gold criss-cross lines on them, but only on one side, the reverse remaining plain blue. This new colour scheme was only available in the United Kingdom until the end of the Second World War in 1945. The old red and green sets were still produced for the export market and were re-introduced in the UK after the war.

Heyday

In 1934, the nine basic Meccano outfits (numbered 00 to 7) were replaced by eleven outfits, labelled 0, A to H, K and L, the old No. 7 Outfit becoming the L Outfit. In 1937, the alphabetical outfit series was replaced by a numeric series, 0 to 10, the L Outfit being replaced by the smaller No. 10 Outfit. Although having fewer pieces than the L Outfit, the No. 10 Outfit became Meccano's flagship set and remained relatively unchanged until it was discontinued a half-century later in 1992. Accessory sets were retained, numbered 1A to 9A, that converted a set to the next in the series (for example, accessory set 6A would convert a No. 6 set to a No. 7 set). As had been the case from early days, Meccano Ltd would also supply individual Meccano parts to complement existing sets. The Second World War interrupted the production of Meccano in England when the Binns Road factory converted to manufacturing for the war effort. The Korean War in 1950 also disrupted production due to a metal shortage and it was not until the mid-1950s that Meccano production returned to normal with new parts being added to all the sets. In 1955, outfits 00 to 10 as well as conversion sets 00A to 9A were available. In 1958, the colours were changed slightly to what became known as 'light red and green' but this incarnation had the shortest lifespan as the colours changed dramatically in 1964 to the black and yellow colour scheme. However, this light red and green period did see the introduction of about 90 new parts, more modern packaging, a new cabinet was introduced for the number 10 set, the first plastic parts were introduced, and the "exploded diagram" instructions made their début. In 1961, a Mechanisms Outfit and a Gears Outfit were added to the range, and in 1962 outfit 00 was withdrawn.

Takeovers

In the early 1960s, Meccano Ltd experienced financial problems and was purchased by Lines Bros Ltd (who operated under the brand name "Tri-ang") in 1964. In an attempt to redefine Meccano's image, the colour scheme was changed again, this time to yellow and black plates, with silver strips and girders. The silver was soon replaced by zinc in 1967 when it was found that the silver pieces marked easily. The colours of yellow and black were chosen because they were the colours typically used by most large construction vehicles of the day. In 1970, electronic parts were introduced, and the current black-coloured plates were changed to blue. The range of sets was reduced by one with the deletion of the old No. 9 set and the renumbering of the old No. 0 to 8 sets to No. 1 to 9. The No. 10 set remained unchanged.

Worked examples

Example 1 — a first encounter with Meccano

Start with the simplest possible case. Write down what Meccano claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Meccano before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Meccano ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Meccano

In research
Meccano appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Meccano in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Meccano is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1900s toys, Construction toys, Educational toys, so understanding it makes those chapters shorter.
In everyday life
Look for Meccano outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
