Nice video with instructions, however a portafilter gauge would be much easier to create. You just need to remove the double spout and screw 2 things on it.
Also, when we say "9 bar" we mean the pressure during brewing. Brewing has a flow of water coming out that we don't calculate with this method. So when your gauge says 10 bar, it will probably give you the right 9 bar when brewing. Setting it to 9 might be a bit too low.
I've actually done a portafilter test also and there is a fraction of a difference as the gaggia classic's boiler is very small and pressure builds up quick. No this steam valve is a classic just drilled out and tapped for the gauge connection & fitting. It seems the classic is a little different in the US to AU as your opv is a 5mm and we have 6mm. Interesting.
@Grant1000T Great to hear from you & thanks for the nice comments. Your videos are some of my inspirations.I'm still trying to track down a nice gauge like yours to do the same mod. They're harder to find over here than you might guess. Do you have a link to the part?
Great vid ! I put a gauge in the front of mine, my vid is on here too. Did you find to get 9 bars of pressure the opv took a few fine adjustments, but it's worth it great coffee. In the end I turned my around 90 degrees anti clockwise. Keep the vids up.
@Hoeboe2k Hi - yes, I did, indeed notice a difference in the brewing. I think you can probably figure out the right grind and dosage for whatever pressure you're at. I've pulled some amazing shots at higher pressures, but getting closer to 9 bar makes things easier for comparison to everyone else in the rest of the world. At that pressure, with the right amount of grinds, to fit the portafilter, the timing starts to match what people are suggesting (25-28 secs, etc.).
Also... fwiw... the sacrificial puck yielded a tasty shot... of course, it might have been enhanced by an off-camera and accidental brief preinfusion.

Do you notice a big difference in your brewing after adjusting the OPV? What pressure do you have it set to now?
