Hi Richard,
Good to see you're still at it... What size stock did you us for the cap... 1.25" ? Nice work by the way! You did a good job with the knurling too... I am using the La Pavoni gauge for the 'C' Lever.
In the past I attached a permanent gauge from McMaster Carr to my '86 Cremina...
If anyone is interested in permanently attaching a gauge to their Cremina...
attaching-pressure-gauge-to-olympia-cremina-t3601.html But I must say it is
involved and costly ( I have sourced less expensive parts since doing that mod... but still costly).
What Richard is offering is truly a great option for any owner of an older Cremina.

Not to mention much more cost effective! As I understand it... Richard you produce the cap, threaded and ready to go... they buy the gauge and mount it?
Once you use his setup to dial in the Cremina to your liking the need to recheck it should be seldom.
Sounds great to me! I'd be interested in one of your caps Richard... Saves me shop time (time I no longer seem to have) It would be for "Granny"... The original '67... 67 Cremina that I would never do a mod to! I would want mine to be a 1/8"
NPT so that I can mount a McMaster Carr gauge... The one I would mount is from pg. 570 of their online catalog. 4066K21 is the catalog #... 0-30 Pressure range. You will note it is somewhat more expensive than the 1/4NPT... 2.5" dial gauges... but it is a very high quality gauge and a nicer look. I've had one on the '86 for about 1.5 years... use it twice daily and never a problem.
Thanks Friend.
