Patrick Pelgroms' Self Contained Junk Yard Hammer
Ram weight 15 kg 180 blows/min.
Patrick was lucky enough, or persistent enough to find some heavy steel for his anvil and plenty of structural steel for the hammer frame.
While the rust makes this look like a roughly built machine it is actually very well built.
The parts are carefully aligned and all the cylinder studs carefully cut to the same length and chamfered.
A custom piston was also machined for this project.
