[Rulof Maker] is a master at making things from salvaged parts, and being an Italian lover of espresso coffee, this time he’s made an espresso machine. The parts in question are a piston and cylinder from an old motorbike, believe it or not, and parts from an IKEA lamp.
Why the piston and cylinder? For those not familiar with espresso machines, they work by forcing pressurized, almost boiling water through ground coffee. He therefore puts the water in the piston cylinder, and levers the piston down onto it, forcing the water out the bottom of the cylinder and through the waiting coffee grounds. Parts from the IKEA lamp form a base for the waiting cup to sit on.
Of course, he takes great care to clean out any burnt oil and gas before starting. We also like how he centers a lever arm on a U-shaped bolt using two springs. Clever. But see the master in action for yourself in the video below.
