Overhaul of my La Marzocco Linea espresso machine from 1993

This lovely espressomachine looks on some pictures admittedly really scary. This is however due to very bad or perhaps even no maintenace at all. These espressomachines are - propperly serviced - a beautiful piece of engineering and are thoroughly build to ultimat solidity and perfection.
So just scroll down to the pictures where the project has advanced and the beauty of the parts has been restored.
