Pile driver.greenspun.com : LUSENET : Junkyard Wars : One Thread
Another in a long list of construction/engineering tools that could be built by the junkyard teams. It could be steam or compressed-air driven or else by lifting and dropping a weight using an interrupted gear mechanism. It could be part of a two-stage challenge where they have to drive pilings for a bridge they must cross in order to ... get to the other side ... supply your own scenario here... Anyway, lots of noise, smoke, and potential for destruction.

Real pile drivers are in essence a one cylinder diesel engine. These things take about ten cans of starting fluid (ether) to start. then they run as a free piston up and down in a cylinder that injects diesel fuel into the cylinder at the top of the stroke.
