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
Review: Mamod SR1A Steam Roller
Review: Mamod SR1A Working Live Steam Roller Young boys and older men who are interested in vehicles of all types are going to love the Mamod SR1A Working Live Steam Roller. This delightfully coloured model is a perfect replica of a 19th Century British Road roller and will provide males from every generation a chance to let their imagination run free. This is the perfect model for creating fun stories, characters, ideas and scenarios. Also, even though this is a boy’s toy, mums, sisters and daughters can still have fun playing and creating these wonderful stories and worlds as a family. The Mamod SR1A steam roller comes fully assembled, so for those of you out there who love the finished model product, but aren’t really too keen on the building process, this is the perfect model for you. Father and son duos looking to either build up an existing collection, or start a new hobby together can jump right into the fun. Due to this model not needing any assembly, it’s perfect for boys who are just starting out their model collecting hobby and because it’s suitable for ages 14+ for non supervised use, the worries of mum and dad concerned about what to buy their teenage son are no more! (Also suitable for dads needing an excuse to add to their collection!) As the pictures show, this model is exceedingly beautiful. The steam roller is simply designed using the most durable metal materials, giving the model a realistic overall look. A more modern and pristine look is given to the steam roller by it being finished with top quality colourful paint. (Get your hands on the model to help give it a more used authentic look! Real life steam rollers wouldn’t look this luxurious afterall. Of course, hardcore collectors wouldn’t dare ruin the exterior appearance of this fine piece, but that’s the beauty of the SR1A – it’s suitable for all!). The model’s dimensions are 255 x 177 x 144 mm, making it a perfect size to handle and not so big that it takes up too much room in a collector’s room. The Mamod SR1A live steam roller is exactly that – live! The model is fully functioning as if it were an actual steam roller used on the street. The model uses solid fuel tablets (which are much safer than the fuel used for models similar to these in the past) and water. Water is poured in, the burner is lit and the steam roller is set to go. Once the model is fired up, it can easily be controlled by using the steering rod to control the front chassis. The flywheel controlling the belt to the rear wheel is powered by a brass piston and cylinder, just like a vehicle in the real world. Steam rollers in real life obviously have the ability to move forwards and backwards; Mamod have put thought into this too, giving their product the ability to travel in reverse, as well as forward. What really gives this model a special touch is the sound it makes; because of the real life components making up the steam roller, the sound made mimics that of a steam roller of its time. This is made possible by the chimney billowing steam from the model’s exhaust unit. There isn’t a live steam roller quite like the SR1A on the market and the high quality materials making up this model ensure a longlasting product you’re going to enjoy today and for many years to come.

Review: Wilesco Showman’s Engine D409
Review of the Wilesco Showman’s Engine D409 The Wilesco Showman’s Engine D409 is a fully working scale model of a steam-driven farm engine, the likes of which would have been used to power agricultural machinery such as threshers and ploughs before the modern tractor. You can still see a small number of engines of this type in the UK today, powering old-fashioned fairground carousels and other rides, as well as at shows and fayres around the country, where they often draw a large crowd of fascinated onlookers. This technically perfect scale replica is painted in traditional colours and carries traditional writing on the side of the canopy indicating its origin in Middlesex, England. It is delivered ready-made, with no assembly needed, and will look stunning either as a static model or a working demonstration of times gone by. On the model itself, the boiler measures 7.3” by 1.8” and has a water volume of 14in. A water gauge glass is included, and the boiler vessel itself is chemically painted black, giving a durable protective finish. A powerful, double action cylinder powers the engine alongside the red-painted, 3.2” flywheel. Depending on the direction of rotation of the flywheel, the engine can be run in forward or reverse. Traditional chain steering as would be seen on a full-size engine of this type is included along with a spring loaded safety valve, steam regulator, steam jet oiler, footbridge, and steam whistle. A clutch engaged gear wheel allows the engine, and dynamo, to be used while stationary as well as when moving. A dynamo lights the eight LEDs mounted on the canopy of the engine. Water is condensed and reused from the engine, just below the chimney. Users will be able to run the engine for up to 15 minutes on each charge of fuel. Each individual part of the engine is carefully constructed from finely painted, high quality, metal. The model is a total of 13” long, almost 6” wide, 8” high and weighs 4lbs. Fuel, in the form of dry spirit tablets, as well as other consumables, are available from specialist retailers as well as online. As a working steam engine, this item is not a toy and is not recommended for anyone aged under 18. Where the engine is being used in the presence of children, close supervision by a responsible adult it required. Steam engines can be dangerous, and if not properly maintained there is a very real risk of explosion. Users should be certain to follow all operating and maintenance instructions provided by the manufacturer. Key features: High-quality, steam traction and show engine Manufactured from high-quality metal parts Fully painted Technically perfect, fully working engine Clutch gear enables stationary as well as mobile use Dynamo powers LED lighting around the engine canopy Delivered ready-made, no assembly needed A stunning static model, or fascinating demonstration of technology from times gone by CHECK PRICES Variants of the Wilesco Showman’s Engine D409 Many Wilesco products are available in different variants – the D409 reviewed here is a working steam model that can be upgraded with a radio remote control.
