|La Marzocco GS2 3 Group rebuild
|Manufacturer: La Marzocco srl., Florence, Italy
Model: GS2, 3 Group, Manual, 220V, Single Phase. 4100W (1600+2500)
Approx Date of Manuf: 1981
Date acquired: August 2004
Working condition: No. Brew boiler cracked as a result of ice formation.
Notes: Posted on alt.coffee for sale `as parts`. Brew boiler cracked in a few places,
very severe limescale build-up. Fortunately all original parts in tact including
paddle group covers and lever.
Well it was an adventure getting it to Hong Kong. Thanks must go to Bill Crossland at LMI for helping me get this
from the seller to his office so he could pack it correctly. The machine was advertised as a non-runner and had
some damage to the brew boiler as a result of water being left inside during winter storage. When it arrived some
trim panels were hanging off, it was very dirty and scale was coming out from almost every orrifice. However the
good part was that some now obsolete parts were in-tact, namely the bakelite group covers and handles.
It is important to note that some of the pictures are not the best in terms of quality. It was an emotional day
receiving and unpacking the machine. Taking good pictures didn`t even figure into the equation.
I have to confess but I was very daunted by the condition of the machine. On one hand it was great that almost all
of the components were there such as the trim and the group components. On the other hand it meant that I had
no excuse not to get this machine in perfect working order!
The brew boiler damage was exactly as I had expected it to be like since other LM users had posted pictures of the
same problem - tks. Barry! It was certainly annoying but looked perfectly fixable. The GS machine and the current
production Linea are fairly similiar in layout. The groups are obviously different but many items such as the sight
glass are still in use today. Without being disrespectful to the GS2, the Lineas of today use much higher quality
steel frames and drip trays. The trays on the GS2 are quite flimsy but still great none the less.
I absolutely adore the body styling. I have to say that the side panels which are made from very thin plastic grow on
you after a while - even though they resemble the crackly plastic of a Ford Capri from the late 70`s! Just magic.
Stripping the parts away to reveal the frame took about 1 hour. As with the NS MAC I took my time because I was
unfamiliar with this machine. It was clear after getting everything out of the frame that this machine would be a really
big job. The frame itself was rusty and one of the first tasks would have to be removing the old paint and rust. I
didn`t need any sort of chemical rust removers as you would do on a vintage car because it was just surface rust
and had not eaten away too much.
I started out by washing away all the dirt, dust and coffee to see what I was left with. After that I just used a wire
bristle cup in a drill and set to work. I then finished it by hand with wet and dry papers.
