The famous “Nodding Donkey” seen from West Texas to Kazakhstan, this icon of the oilfield is available only from Timberkits US as a kit or a completed model. Operate the crank handle and the beam operates the pumper rod while our “asset manager” gives you a friendly wave.
The Pump Jack is one of the more sophisticated models in that it has multiple examples of physics and engineering. The beam is a classic lever weighted at one and connected to a push/pull pump mechanism which is driven from an enclosed cam box with a half flywheel on each side for the conversion of movement into kinetic energy and then released as rotary motion to the beam via to short pushrods. Underneath the model is a lever with the fulcrum off center that converts vertical motion from the cam box to the movement in the man via pushrod and a pivot in the upper body.
Each model kit comes with
- All wooden components shaped and drilled
- Sandpaper for finishing
- PVA glue
- Parts list
- Comprehensive instructions
The models are manufactured from renewable wood sources and are design for age 9 and over. Younger builders may require the assistance of an adult. The models, both kits and built, are not suitable for children 3 years and under due to the risk of choking on the small parts.
