The time has come to start the restoration of a machine as I still never had redone, a Conti Prestina.
It is a 70’s lever machine, by the famous manufacturer Conti. The design of some point is quite simple, a welded steel frame, the quality is the same as for the Empress, the welds are not too nice. And also it probably could be more, as in design of the boiler cover, which brings together all the necessary connections to the operation of a machine in a small space.
I will do more comprehensive pictures of the assembly when I finish the beauty cover-up but it is really a very nice casting and machining.
The group design is very similar to that of Cimbali Eleva. It is composed of several pieces, brass, cast iron and steel. It is also a beautiful production, and an interesting design. I’m not surprised, moreover, that it is still produced by Conti, as is also the latest Faema lever group via the Spanish manufacturer Quality Espresso. It is connected to the boiler, but the long and airy link could give him closer characteristics to a thermosiphon, can not wait to try it to know. Machining treated, bearing assembly, it is already superb, but the ultimate luxury is really the sleeve with its hard chrome plating. I’m not always very fond of Conti but there, there is no doubt, it’s very beautiful. The bottom of the group, the female bayonet who carries the filter holder is removable. Well… use it til you need to replace would take a few decades of use …
The boiler is made of copper in one piece solderless, I think they were extruded, or maybe pushed back, not sure, but in any case here too there is no compromise on quality, this is beautiful material.
Once again this machine shows the poor interest of aluminum in coffee makers. The slightest leak, and more generally moisture, almost constant prevailing in that environment, always ends to weld the screws into the holes and makes very complicated disassembly, most often impossible without breakage. The flange is broken, I will have to find a replacement …
To be followed…
