Review: Burrell Showman’s 8 NHP No.3938 ‘Quo Vadis’
Review of the Burrell Showman’s 8 NHP No.3938 ‘Quo Vadis’ This magnificent miniature replica of a Showman’s road locomotive revisits a golden age in travel, dating back almost 100 years. These locomotives were mainly used to transport a fun fair or circus from town to town and, once the destination was arrived at, it would then serve as a power source for the entertainment. A far cry from motor vehicles today which whizz past you in an instant, the arrival of this beautiful piece of machinery would have been easily visible on the horizon with the emission of vast plumes from its slender chimney. The fact that Showman’s road locomotives had numerous uses – from vehicle to power supply source and beyond – was just one reason behind their immense popularity. This beautiful miniature model is aimed at collectors who appreciate fine vintage craftsmanship. It will also interest those who collect models and artefacts relating to modes of transport dating back to the 1920s. Introducing the iconic Quo Vadis model All of these road locomotives were given names – much like car models of today – as well as an identifying serial number. This particular model is a direct miniature replica of the much-loved ‘Quo Vadis’, number 3938. Purchased in 1922, the Quo Vadis travelled the roads of England for well over a decade before being sold on to amusement contractors in 1935. By the time it was once again purchased, in 1965, it had been retired ten years earlier and was in a sad state of decay and disrepair. Quo Vadis was subsequently restored and is now a truly iconic symbol of the era to which it belongs. This collectable piece is a representation of the restored locomotive which, by extension, also makes it identical to how the vehicle original appeared upon completion of design in 1922. Showman’s road locomotives stood out for many reasons, not least their attention to aesthetic deal. Three key aspects became signature characteristics of these stunning vehicles – the canopy which runs the length of the locomotive, the tall and slender chimney and the highly decorative, skilled paint work. Attention to detail that will impress the discerning collector The Quo Vadis boasted all three aforementioned characteristics, and they are superbly brought back to life in this eloquently designed model. Only 1,500 of these miniatures have been commissioned, each of which comes with a certificate of authenticity. The structure is made from diecast metal as well as plastic components. It is suitable for children of all ages but will probably be best appreciated by an enthusiast of vintage road locomotives. Perfect for display at home, this model will appear particularly well in a cabinet that is accompanied by appropriate lighting to illustrate its delicate features. Online reviews have praised the model for its historic accuracy, customised packaging and impressive attention to the smallest of details. Key features Outstanding collector’s item Historically accurate One of just 1,500 miniature replicas commissioned across the globe Comes with certificate of authenticity Eye-catching attention to detail Appropriate for children and adults Presented in customised packaging CHECK PRICES
Review: Sunnytech® Hot Air Stirling Engine Model Educational Toy Sc02
Review of the Sunnytech® Hot Air Stirling Engine Sc02 The Sunnytech Single Flywheel Hot Air Stirling Engine is a well-crafted, fully working model which demonstrates the operational principles of Stirling engines. What is a Stirling engine? A Stirling engine is an external combustion engine. That is, it is an engine that gets its energy from an external heat source, in contrast to the internal combustion engine where the heat input is generated within the engine itself. The Stirling engine was invented in 1816 by Robert Stirling, who wanted to create an alternative to existing steam engines, whose boilers could often explode because of the high steam pressures used and the strength limitations of the materials available to engineers at the time. How does a Stirling engine work? Like all heat engines, the Stirling turns heat energy into mechanical energy. The key feature of the Stirling engine is that it uses a fixed amount of gas – usually air – enclosed in a sealed container, with the heat consumed by the engine applied externally. This means that the engine can run on just about any heat source, including coal or gas, solar energy, chemical reaction and nuclear energy. It can also work with very low temperature differentials, which means a Stirling engine could be powered by body heat or even the steam from a cup of coffee. And because it uses heat from a constant source and does not, like an internal combustion engine, rely on a succession of explosive ignitions, the engine runs very quietly. The heat source used in the Sunnytech Single Flywheel Hot Air Stirling Engine model is supplied by a small methylated spirit burner, which comes included, and the engine’s output is delivered – as the name suggests – by a single flywheel. Model features The Single Flywheel Hot Air Stirling Engine is robustly constructed from steel, copper and aluminium, and comes fully assembled, which means that you can have it up and running within minutes of taking it out of the box. Just fill the burner with meths, light the wick, let the working fluid (air) heat up for 30 seconds, give the flywheel a spin, and off it goes. The model’s main features are: Specification: Single Flywheel Hot Air Stirling Engine Model No.: SC02 Speed: 1300-1500rpm Size: 130mm X 80mm X 115mm Materials: Aluminium, Copper and Steel Weight: 500g Colour: Silver The Single Flywheel Hot Air Stirling Engine is an ideal collector’s item for engineering enthusiasts, as well as an engaging educational demonstration model. Most importantly, it is lots of fun. It should, however, only be used under adult supervision, and it is not suitable for children under 10 years old. Customer reviews of the Sunnytech Hot Air Stirling Engine are consistently excellent. People who have bought it are particularly impressed by its quality and performance. In today’s world, where everything is made from plastic, the look and feel of a solid, tactile piece of high-quality workmanship is immensely satisfying. It has an elegant design, is well engineered and constructed, and runs like a dream. CHECK PRICES
Model Steam Engines: Explaining Scales
Model steam engines are manufactured according to a variety of scales and gauges. The choice of scale and gauge is crucial as they are the major differentiating factors between the model steam engines. What makes things more confusing is that many model steam engine enthusiasts, and even seasoned fans, often use the two words ‘scale’ and ‘gauge’ interchangeably. However, they are two distinct attributes. For starters, scale establishes the size relationship between the model engine and the real one. It is often represented as a ratio, such as 2mm:ft or 1:148 scale. This means that every part of the model engine is one-one forty eighth the size of the original steam engine. On the other hand, gauge is an attribute of the railway track. It is the distance between the inner edges of the track rails. Gauge is a more important attribute to consider, when purchasing a model steam engine. Let us understand why by looking at the main gauge types. O Gauge O Gauge model engines were produced from the beginning of the 20th century, and were among the most popular models for a long time, until the 1960s. Since then, they have lost their popularity and are difficult to find. They were manufactured in multiple scales from 1:1.48 to 1:43.5. But, they eventually lost their fame to smaller scale models. O Gauge model steam engines are not known for their finer details and accuracy. In fact, they were designed for pre-adults and therefore, cost-effectiveness, and durability were given more importance. Although they are valued by some collectors because of their rarity, most of the collectors and enthusiasts, with an attention to detail, do not prefer these models. OO Gauge OO Gauge or Double-O Gauge model steam engines belong to a family of model railway systems, which follow the standard gauge model. The OO Gauge has a railway track that is 16.5mm wide, and is built at a scale of 1:76.2 or 4mm:ft. A highlight of OO Gauge models is that they rank very high in terms of realistic appearance and finer details. For this reason, they are of great value to serious collectors. Moreover, many of the manufacturers also place a lot of emphasis on durability and affordability. Naturally, they are among the most popular model steam engine categories today. G Gauge G Gauge models are big in size. They are manufactured on a scale range of 1:22.5. Because of their relatively huge size and highly durable construction, they make the best garden railway models. Their extensive use as garden models have led to modern train enthusiasts to believe that the G in G Gauge stands for Garden. The truth is that the G comes from groß, which means “big” in German. Oh yes, the G Gauge models were born in Germany, just like many others. A large scale means that the parts are not as intricate as the other models, say O Gauge for instance. Therefore, they are easy to produce and are readily available. Final Thoughts As you can see, the choice of gauge will be quite obvious to you based on the purpose of your purchase of a model steam engine. If you want a garden mode, then G Gauge is what you need. If you are a collector who enjoys the finer details, then OO Gauge is what does the job for you. However, if you are buying a model engine for your kid, then O gauge is just the thing.
