Have great fun with this working replica of an ingenious device used to lay siege to castles. Those wishing to storm the defences should use soft pellets as missiles and pebbles for counterweights.

This intermediate level kit is aimed at builders who have become more adept at Timberkit construction or feel confident in building a model that’s slightly more complicated.

Automata kits are ingenious and fascinating combinations of wooden parts and mechanical linkages. Supplied as a kit of parts with assembly diagrams and glue; building each model is an education in itself and the end result wonderfully entertaining. The kits are a joy to make for all ages from 9 to 90 years; younger children can get involved with adult help.

All the wooden parts come from sustainable forestry and are fully machined with no further need for specialist tools.

Finished model dimensions: Width: 340mm, Height: 170mm, Depth: 125mm.
