Wiggers

With this impressing small finished model we retained our typical model engineering character.
The flying wheel is a cast iron part and not a CNC-lathed disk.
All brilliant parts are high-class gilded, i.e. they won't tarnish.
The parts will stay brilliant even after 20 years.

We also retained our WIGGERS-RED as the basic colour.

Heating cylinder and displacer consist of a heat-resistant glass of excellent quality. The wick of the burner is made of fibreglass. The operating piston and the bearings consist of self-lubricating material.
The model is mounted on an oiled wooden plate (70 x 160 mm) made of Abachi-wood. It is heated by normal spirit. The total height is 80 mm.

This item is carried as an in stock item. If the shopping cart allows you to order the item it will be shipped within two days.

This Stirling Engine is equipped with a bigger fly wheel, which is running between two machine pillars and ensures a good driving mechanism. Regarding the height of the model the heating oven with chimney is conspicuous. The heating oven better concentrates the heat around the heating cylinder; it is operated by a smaller flame and it produces a longer run. Optically the machine pillars and the heating oven, painted in WIGGERS red, give the machine a very appealing construction. All other parts are gilded, so that the model has a good appearance after years. The beech basic board is bright natural and protected with clear lacquer to contamination.

Of course the burner pot is gilded like all other parts, it has a fiberglass wick and the handle of the burner is turned beech.

Measurements of the model: length = 185 mm, width 90 mm, height 170 mm.

The model Stiwi 2 will also be delivered like model Stiwi 1 in a valuable wooden box.

This stirling model was developed by WIGGERS model engineering. It demonstrates a unique and fascinating movement of levers and rods. The model is not the most fuel efficient but it is optically fascinating and mesmerizing to watch run.

The movement of the heating and cooling cylinders are constructed in such a way that the whole mechanism is executed by the need for only one crank pin. The connection rods, levers and angles provides for a fascinating process of movement. The adjustment of the number of revolutions is possible through the control knob located on the side of the engine. The slower the model is run with its many side mechanisms, the more appealing is the process of its movement. The model generates a remarkable amount of power due to the big dimensioned fly wheel. This power can be used to run accessories with the pulley attached to the flywheel. The surface is painted and nickel plated to prevent tarnish and corrosion. The design is such that the model is free of maintenance and is heated by methyl spirits. The grooved beech wooden base board of the model centers a an acrylic hood, which gives the model protection. This model is medium sized and needs the following place: length: 280 mm, width: 170 mm, height with hood: 230 mm.

WIGGERS Stirling model engineering is glad to be able to present a model of a special design: the worldwide first Rider-Stirling machine.

It is the model of an original Rider Monski machine probably finished in licence before 1885 in Germany by Alexander Monski.

We succeeded to create a model whereby model engineers always failed. After nearly two years we primarily succeeded to set a perfect functioning model on foot – for pretentious Stirling model engineers a real technical dainty.

Technical information:
Ttotal height over chimney 400 mm, Width 170 mm, Length 190 mm,
Flying Wheel D-135 mm, Piston D -32 mm

Rider Ericsson: hot air pumping machine

The original machine was patented in America in 1888 and was formally, as well as today, a classic model among the STIRLING machines.

It was used on ranches to fill up animal watering troughs. Our model, a precise copy, in the measure of 1:4
