This restoration keeps going, the parts i'm waiting are finally in transit and i expect them next week. Right now that's all i can do, i need them to mount the lever group.
I had a minor/major fright, time will tell, with the glass level... It wasn't secure when i was fasting it rotated and i chipped it in a extremity... Iuckly i'm safe for now but i will need to replace it in the future.

I have already finished the resto!!! I have been drinking coffee from it in the last 15 days and i have to say it was worth all the time spent on it... It's delicious.

Although not having yet a proper tamper i found very easy to extract good espressos from it once i managed the grinder coarseness.

Presently i can only manage to take doubles because my 7 grams filter hits the sleeve and blocks the portafilter attachment. I already ordered other 7gr, this one has a groove and hoppefully it will give clearence to the cylinder sleeve...
My doubles are taken with a 26mm filter on wich i squeezze 15 grams of coffee. I don't measure the espressos extracted as i use coffee cups as the ones commercially used here and visually the coffee have the same volume.

The only issue it have is with the over pressure valve, it's a little noisy because it doesn't make a perfect seal and sometimes releases some water. I already have ordered a contemporany one and i will install too a temperature PID management.

The pressurestat, the machine part wich i fear most... functions perfectly. It isn't loud as i supposed and have a deadband of around 0.3bar. I have it sutting off the heater at 1bar.

I buyed coffee from a local. I tried a classic blend and it tastes great! I also bought an arábica bourbon from Rwanda and i start to know what you guys talk about... great stuff!

Here some photos from the first day!!!

Yes, i had the steam and the water tap switched, they are fine now... but i only noticed when i tried them :p

And i'm waiting this...
A gift from my father in law, i'm a good boy :D

So... Thank you guys, you helped a lot and such an inspiration!!!!!

Thank you sir! My only credit is the colour, in my opinion helps to put it contemporary although the design is predominant in this matter.

This is one of the top LSM rebuilds I've seen. You restored a machine that will be passed on to your children's children. Bravo!

Looks great. Too bad you won't be seeing much of the fancy back of the machine where it's located.
