Four interlocking gear wheels in a display case. Art and engineering in perfect harmony.
This project is also on Instructables
The parts of this project are cut out from three millimetre plywood using a laser cutter. In this case, an HPCLaser 3050.
The plans for making this project are available for everybody to download for free. As well as the plywood you will also need a piece of dark coloured paper as a background and a sheet of one millimetre thick clear acrylic for the front of the box. One final addition, you will need three pieces of six millimetre wooden dowel. Two of them twenty four millimetres long and one eighteen millimetres long.
The HPCLaser in action cutting out the parts.
All the parts apart for the dowel pieces cut out and ready to go. The blue piece is the clear acrylic front with its protective film still attached. Having cut out all the parts follow the instructions below to assemble the gear display.
Fit the knurled wheel through the remaining hole in the base plate. It should turn easily in the hole. Fit the small gear into place on the dowel so that it just touches the spacer on the base. It should turn easily via the knurled wheel.
