Eitech Construction Sets

Hi folks, Doc here. This time we'll look at another metal construction toy company from Germany: Eitech. Unlike most other German systems, Eitech is a relative latecomer to the hobby. The parent company was founded in the city of Pfaffschwende in 1955 as a metal fabricator, but production of metal construction sets did not begin until 1977. In the mid-1990s, the entire product line was revised, and new products were added, including larger building sets with over 1000 pieces and solar powered sets and motors.

The current Eitech® product line is extensive. Four different families of building sets are available under their CONSTRUCTION® trademark, starting with their "Beginner" line of all plastic sets designed for young builders. Next are several different classes of metal construction sets, including small, starter sets, mid-range sets, solar sets, experimental electric sets, and finally a group of large sets with over 1,000 pieces that are designed for the advanced builder. In addition, a line of accessory packs is available that feature a viariety of spare parts, motors, solar panels, and more.

Smaller sets are packed in cardboard boxes, the parts arranged in vacuformed plastic trays (see above). The largest sets come packed in plastic storage cases with integrated handles. Inside, the parts are not arranged in trays or compartments, but rather are simply packed in several heavy plastic bags. Manuals are large and printed in full color, with detailed step-by-step model building instructions, although only a limited number of models are shown.

Metal sets feature a large parts inventory, the majority of which are made from nickel plated steel. Plates, strips, brackets, and disks typically range from 0.8mm to 1mm in thickness. Hole spacing is 10mm, the same as the Merkur system, although the holes themselves are larger: 4.5mm diameter for Eitech, 3.8 for Merkur. Eitech axles are 4mm in diameter. Screws are pan head with Philips slots, size M4, and come in four lengths: 6, 8, 12, and 16mm. Nuts are hex.
