hi, just to share some details of this machine, for the records and general information

recently found it close to my place, sad story, no more comments
it was a nice combo coffee machine + grinder

to make a long story short,

this is a 7 liter boiler, one group, manual lever machine
one resistance 650Watt
vapour and hot water taps
manometer, and pressostat, and 2 safety valves

yes, two valves, which BTW i converted into 1 valve and 1 cap to fill in the boiler

i cleaned, descaled, change seals and gaskets, new resistance, e voila !

it makes good coffee, and works perfect.

a bit big for my place, but i will try to survive with it

[FONT=&quot]meanwhile i have an idea for the manual water filling procedure

as a mechanical eng, i know there is not a reason for two safety valves so we will try this:

1- put a new safety valve in one of the holes
2- use the other hole as a port for filling water
3- add an anti-vaccum valve making a change in one of the 90 deg. pipes

to implement my water filling idea:




combining the threaded part of the used safety valve and my old lapavoni cap

i threaded the brass piece in order to run a bolt through it,

also modified the bakelite cap to insert it, using some epoxi to reinforce and block it

still need to get a shorter SS bolt to complete it, but tried it and it does the trick
