Hi All I have been finally measuring my pressure on my Rancilio Espresso Machine, which was reading around 10 to 11 bar and have adjusted it to around 8.5 bar. Seems to be extracting a bit better now. I find however now, when trying to froth milk, it is still very liquid and not frothy enough, yet has reached it's temperature during frothing. Anything to do with the pressure on this? Any ideas how I can improve this? It has the single hole nozzle. Thanks
This impresses me, the idea of being able to see precisely how much pressure I'm building up in the chamber before applying pressure: https://www.lamacchinadelcaffe.com/en/ricambi-la-pavoni-esperto.html. They advise that they are made to order for whichever diameter you need, so what looks like a well made lever and a brass piston in my post-millennium machine.
I wanted to check my brew pressure occasionally as all of these bypass type valves do have a habit of drifting out of spec after a while = spring will get weaker, screw works lose etc. but as i only have one threaded PF and one naked its a pain to keep un-screwing the spout to put a pressure gauge on, so thinking it through the seal is done at the basket so if you have a blind/back flushing basket all you need to do it tap into it to read the pressure and there is less volume to pressurise so its easier to see the pumps profile. my answer = Ok i have now got a price for all the bits to make the Pressure gauge basket. Learning from the Mk1 this will be for the Mk2 as my original one used steel hydraulic fittings and is already showing a tiny bit of rust, so i have price for chrome plate brass. they are going to be £15 including postage & packing as the bits to make them are £11 so im making about a pound a unit!! and this will include a £1 donation to Glen for running this site. Please let me know by PM if you want one, payment Via paypal or bank transfer is cool. will get the bits at the end of this week to make them.
