My encouragement to you is that La San Marco group is brilliant. You will be achieving paint like, heavenly shots over and over with little effort. It will become your favorite machine I bet.

If you want a bottomless portafilters for it Izzo sells a really nice one for their Leva with tight tolerances, I believe it should fit but check with them first to be safe.
Thank you the encouraging words. I have no doubt it will become my favourite... i only have the one advertised by Clooney :oops: :roll:

I will check the bottonless portafilter as i really will have one... those extractions are porn.

Successfully made a piston disassembling tool.


I'm having difficulty with cleaning the oily residues.

Busy days those last ones but achieved to dismantle her almost completely.

The boiler had the bolts completely seized, to avoid doing any irreversible damage i take her to an expertize...wich made such a sloppy job that i don't want talk about it. I know the man and it isn't is kind of work so don't know what happened.... maybe a bad day, sure my own fault to knock his door at a monday morning.

The parts are in a citric acid bath right now. In the rush i forgot to take photos but they had a lot of copper oxide and sulfide deposits. The citric acid really does work really good when warm as i have read but i don't have how to keep the bath warm and it's at environment temperature. It will take longer but i hope it will do his job.

Meanwhile i'm evaluating the parts to chrome, i wish tho take them all but i need to be money conscious.
