Reading it a second time, I wonder if this device that "keeps the brewing pressure always at the same level" is an expansion valve (OPV). That would be somewhat disappointing... one of the features I like most about lever machines is that the pressure profile isn't flat. Steve complains about my Microcasa's spring because he loses "the feel" for the pull. Then again, an expansion valve + spring-powered piston would eliminate the vibration question from pressure production, which may be behind that elusive clarity we've been talking about.

This machine is sounding more and more interesting. I'll have to check if any of our sponsors would like to see such a machine featured On the Bench.

Gosh, it must be good to be the king, all I ever get from the sponsors are bills attached to boxes

Ha!

Before anyone gets jealous, ask Abe about how much "fun" he had writing up the Brewtus. Do it offline though because this site is PG-13 and I don't want to moderate his R-rated response. I do enjoy the learning experience, but I prefer not to dwell on how many hours goes into each writeup. Realistically, the chances of a sponsor showing any interest in a niche machine like the 1EL are zero. Who knows though, I think that EPNW has some commercial lever machines...

I tried to come up with a PG-13 version of my take on this, but it ended up incoherent, with a lot of "$$%%$#@@!" for beeps. Reviewing any machine is a lot of fun. It is a process of discovery, and if you are an explorer, you will never get bored. However, translating that experience into an article is a whole different ball game. It is no longer about the experience and all about the writing. Some people are faster than others in that, but no matter how fast you are, to do a good job, the article will go through numerous revisions and by the time you're done, it will have occupied weeks of your leisure time. Now, if you have Dan for an editor, and Chris Tacy (Malachi) as your peer reviewer, get ready for a blood bath. It took me a week just to clean up the blood stains from the slaughter that the Dynamic Duo brought upon my masterpiece.

However, that said, I do not regret it. It was an interesting ride. Dan is a pleasure to work with, and the whole process was rewarding. I just don't think I'll do it again. To those of you who are considering writing, I would suggest to start with a Bench review. These take less time to put together, they are much more fun to do, and they are intimately connected to the experience.

I want one of these levers on my Brewtus (what would we call it)
imagine a Brewtus with no noise or vibration, the clarity in the cup of a lever, and the spot on temperature control.
AWESOME!!!!!!!!!

Sweet! The only person who can actually move this from a pipe dream to reality is Sean Lennon. But that dude is way past us. He is now on an all new pump setup with programmable pressure profile, that surpasses the lever by a mile.

A pneumatic powered transient fluid processing unit with logic control augmented with an auxiliary lever controlled pressure unit with tactile feedback.

I received an email from La Pavoni today and they say that the machine is not a HX. As to the inner workings, the directed me to this document on their website. Apparently the Pub 1EL is mechanically similar to their Bar L family of lever machines (although no 1 grouper there). I am not proficient in interpreting the parts diagram but as far as I can see, there is no HX nor is there an OPV.

I assume that "the device that keeps the brewing pressure always at the same level" is in fact the spring. Just my guess...

I came across an exploded parts diagram that has me fascinated!

Hi, there!

Has anybody ever tried this machine? La Pavoni say they don't sell it on Italy

Márcio.
