This was the first model I built when I re-discovered Meccano building in 1980. This was shortly after I had purchased The Hornby Companion Series book "The Meccano Super Models " Geoff Wright, 1978. At the time my Meccano collection was mainly what I had as a child with a few additional parts purchased on second hand stalls. To build the model I had to purchase some new sprocket chain, 4 of P/N 133 corner brackets and two P/N 50 slide pieces. I remember I had to wait several weeks for the corner pieces as Geoff Wright of M.W. Models in Henley-on-Thames was awaiting a delivery from the Calais Meccano factory. Power for the engine was supplied by my childhood E20R Meccano motor, well geared down. In May 2009 I decided to build the model again but this time using 1978 dark blue and yellow parts. It is much the same as the earlier model but since I first built it I guess I have honed my building skills and somewhat increased the parts I have available. Red and green are probably the colours for this model but I think it looks very smart in mainly, shiny, new condition 1978/79 parts. The model is driven by a small modern black 6 volt French motor to a tensioned belt drive to the six inch pulley/flywheel. I replaced the chain drive to the governor, partly because it kept coming off at high speed, using instead a Mamod steel cord belt. As you can see I also filled in the cylinders with flexible plates.
It is a very enduring model, recently I decided to convert it back to electric power,driven by a non-Meccano 12 volt motor inside the case of an old Meccano crane motor. This you can also see on YouTube click below.
By modern standards it is hardly in the "Super Model" class but it has always been a favourite of mine. The instructions for "The Single Cylinder Horizontal Steam Engine" originally appeared in 1928 as Super Model leaflet No.11 shown above is the later version 11A from 1936 and could be built with the contemporary "K set". It was obviously popular as it was updated and reprinted several times. This last version shows the then new strip plates, this is the version I originally built and is shown below. Interestingly until this version the instructions still showed the open ended P/N52 obsolete in 1927. Many other versions of this type of engine appeared in Meccano manuals right up to 1978. A few drops of light oil and the engine hums along nicely, as you can see in my video. Its a lovely little model I think and lends itself to easy modification. Click here or on the image to link to the original instructions. In 1928 Meccano also made this model available to dealers, ready built as a "demonstration Model " this could be supplied with or without a 6 volt electric motor. The price was at the retail cost of the parts with no charge for labour. In July 2023 I built the model in original 1930 red and green parts building it at close as possible to the original 1928 SML 11 instructions. Click here to see pictures and a video.
Horizontal steam engines of this type were the work horse of many manufacturing industries
through out the 19th century and much of the 20th. The engine would drive many pieces of
machinery through a system of belts and pulleys.
There is a nice example of this type of engine in the Gladstone Pottery Museum in Stoke-on-Trent painted red and green.
