Massive Marble Machine 1
The massive marble machine offers all the fun of the smaller machines but with a very satisfying clonk as the ball bearings go round.
The kit is made from 6mm poplar plywood. It is basic slot and tab construction and a small amount of wood glue (not supplied) is required for the joints. The machine comes with 8 x 20mm ball bearings for normal operation. The assembled machine is 200mm x200mm x200mm in size.
Assembly Instructions are the same as for the normal machine and can be found on instructables
