In the 2019 version, you don't have enough space to put the pressure gauge on the front. Inside, there's a plastic holder for the controls. I was reworking a 2019 model once and put a pressure gauge on the side
Hi, I notice that the gauge needle is stable, is this because of the capillary? I have a portafilter mounted gauge and the needle vibrates very aggressively. Thanks
The one on the portafilter I use is a glycerin manometer, glycerin keeps the needle from vibrating. The one that I installed in the casing of the coffee machine is of good quality and does not vibrate. Maybe you have the wrong pressure gauge? Maybe your prortafilter pressure gauge is only for air installation? I used to have one that came from the air installation and it was trembling terribly.
Been thinking about this mod and the dimmer switch mod instead of the opv, why have the pump waste water when I could just reduce the flow to 9 bar. At least then I'd have the option to go higher than 9bar should I wish. I think I'll leave the PID out for now, mine seems to pull shots just fine to be honest, no difference than the commercial gaggia except for the 10 seconds to wait for the steam.
Hi I don't know whether you still check comments on this video but if you do, could you please let me know what do you call for the wire that is connecting the pressure gauge and the Tee joint?
You mean the widia hole saw that I drill the hole for the pressure gauge? allegro.pl/oferta/otwornica-widiowa-wiertlo-koronka-metal-40mm-speed-8436402139
I think you're supposed to drill slower speed... I have to drill bed frames slow seems to work better... Not much of a deal with this - but if anyone has comments on speed LMK.
@@Gaggia_Fixer Assuming the OPV is set correctly does placing the gauge after the pump give an accurate result? I'm looking to modify a different machine than the Gaggia so I'm not sure where to put the T fitting. I thought about right before or after the OPV, that would easier placement wise in my machine. Would that be accurate?
@@221b-l3t Hey, it doesn't matter where you put the pressure gauge. The manometer will measure correctly whether it is in front of the OPV valve or if it is behind the OPV valve.
I'm going to do the same mod with my Gaggia Classic and ordered all the parts already... Just not sure if I need anything to fit the T-connector in the original tube from pump to OPV? Just cut the tube and screw it in? The ends of the tube on the original connectors to pump and OPV are thickened... How to achieve this in the additional T-connector? Or not necessary at all and it keeps tight by just screwing it on? I'm afraid to cut the tube and it won't be tight after... Means no coffee until the spare part would arrive! Would very much appreciate an answer! Cheers
@@camane00755 Hello Carlos, I bought the pressure gauge at www.espressoxxl.de/ (this guys are very knowledgeable and helpfull if you ask any questions by mail btw.) and most of the other parts at www.landefeld.de/ In the end I didn't cut the hose, but connected a T-connector directly to the angle piece of the pump... Hope that helps!
@@christian3962 Hi again and thanks for your quick answer, do you mean this T-connector = www.landefeld.de/artikel/de/voss-fahrzeugverschraub-t-einschraub-8l-kompl-/253452
Man this was a measure 5 times cut once job. Good job.
Very cool! I've got the 2019 version and would love to throw a gauge on there some day.

Awesome video and upgrade want to do this now, small tip for drilling stainless it likes to be drilled slowly 👍🏻
Vert good work! Which model/year is this gaggia classic? Pro or not? Thank you!
That was a big pilot hole 😄
Great job anyways!
Thanks for sharing. Could you tell me the function of the coil in the copper pipe
i think it has no function except an extension of pipe
It was gas powered driller that you used, wasn't it, do you think that home use battery powered drillers are able to make through stainless?
Hey, I'm using a 230v cordless drill. I think that if your drill has a fairly high speed, you can easily drill this hole.

What diameter is bore drill bit? Are you based in Los Angeles? Can you do that to my machine?
You are awesome

How did you install the tee connector to the tube? Did you cut the tube and attatch each end to the tee connector?
Yes, you have to cut the tubing to connect to the tee.
Hi I don't know whether you still check comments on this video but if you do, could you please let me know what do you call for the wire that is connecting the pressure gauge and the Tee joint?
It is a thin brass tube/pipe to send pressure from pump to gauge. You can bend it by hand to line up with T fitting.
Great video thanks - might brave taking a drill to my beloved machine!
Hi great video. Can you tell me what size is this t connector?
You mean this 1/8" threaded tee for 6/4 mm tubing ?
@@Gaggia_Fixer Yes. That one that connects the tubing and pressure gauge. Thank you.
Elegancko! Jakbyś kiedyś montował PID'a do ECM Casa V, to chętnie popatrzę. ;) Pozdrawiam.
No jest to ekspres który mi się marzy więc w przyszłości któż to wie pewnie będę taki modzik robił :)
Hey man
What fittings did you buy for the gauge? I need the little T. Can you describe and list that for me please? Thanks

Hello my pid works very well but it works even though the switch of the machine is turned off
What kind of drill bits do you use for drilling through the metal ?
You mean the widia hole saw that I drill the hole for the pressure gauge?

Great mod. Is there room behind the front plate to center the gauge (left to right) between the buttons and the badging?
Yes, in the Gaggia V1 there is one room for the gauge to be centered but then you have to remove the Gaggia Classic emblem.
Damian Witoński - Roger that. Thank you.
@@Gaggia_Fixer Hi, thank you for the video ! do you think it's possible above the gaggia classic inscription ?
What are the parts you used? Model numbers for the gauge and Tee? Mostly interested in what to call the tee and what size those lines are. Thanks

@@Gaggia_Fixer Seems like the gauge is not available, can you share any alternatives it would be great :)
Thanks for nice video - appreciated!
Does the pressure gauge pointer flutter during use?
Not always, but it happens often.
@@Gaggia_Fixer I see, it seems that people have solved this by using pressure gauge filled with viscosity fluid like oil
That’s cool
question: where can u adjust the pressure to 9 bar after u installed the gauge? thx

super!

I don't know what that has to do with anything?
I wish I had the skillset to do that.
Then send it to me to Poland and I'll do it for you :) The only question is where are you from? and will it pay off?
9 bar on such a small pump? Thought it would need higher pressure
The pump is able to deliver up to 14bar, but nowhere is it said that you need so much pressure to make a good espresso.

Exactly :) You cut the hose and push it in, and the nut will tighten it in place.
