Nuova Simonelli Oscar:
I picked this little one up about a year and a half ago ±. It's been a trooper but I desire to learn more and understand this machine and others. The entire universe of coffee has been a fantastic voyage and this seems like an appropriate way of continuing my education. Know that I am a novice when it comes to these insides. I do not profess to have anything but a good sense of curiosity, looking for good questions and good answers to apply.
From my reading and exploring over the past few months I've found a wealth of thoughts but where they fall in difficulty, ability, and time I'm not sure, thats why I'm here. Help me sort the signal out.
- Addition of a Vacuum Breaker
Addition of Steam & Pump Gauges
General Temperature Adjustments
Advanced Adjustments via PID installation
Pressure Limiting Valve Adjustments
Not everything is necessary; I just wanted to think without being boxed in. I think this is everything I could really do to the machine. I think some things stack. If I were to be cutting copper for a vacuum breaker then it doesn't seem so far an idea to tie in some gauges. Course I've never cut copper so if that has a large learning curve then both of those seem of vague relevance.
In the next week I'll have most of my tools at the ready. Scace, Omega therm, probes, PF gauge
Ebay has not too bad a price on the Fuji PXR3, but I don't know the extent or method for what I would require to do this fully.
Steam wand/Vacuum Breaker
At first I thought this was a definite. I've always run the unit 24x7, but I read on how people timer theirs and that sounded pretty nifty. Then I saw a number of techs writing that said that stresses the machine, seals, and wears the valve out which made me ponder the real need for such a device. I'm easily compelled but adding a breaker now doesn't sit as high as it did a few weeks ago.
Pressure Limiting Valve
I've yet to find this bit, can someone help point it out and how to modify it? I've got the classic NS Oscar that when it's got a blind in it still doesn't release the pressure.
Clockwise more pressure, counter less? Once my gauge comes in I should be able to tune this right?
Temperature & PID Adjustments
Now my hunting for information really drops down.
- How do I adjust the pstat?
From where do I draw my best measurement?
How do I rig a PID into this?
Any help, tips, resources, or ideas/things I'm forgetting are always appreciated.
