Simple Marble Machine, Wooden Rolling Ball Sculpture

£7.99

This hand-cranked machine is very easy to assemble and is suitable for use in school projects to teach about mechanisms. Also great for a rainy day project with the (grand)children. It is unique in the sense that it is built entirely from laser cut MDF. Slots and tabs are used in the design to ensure all parts are perfectly aligned. A minimum of sanding is required. 9.52mm balls are included.
