Bezzera lever not quite quiet...

[zix]

I was just wondering - is anyone else hearing the spring when you pull shots? Dang-wang-lang like the feather in an old sofa as the lever goes up? I do on my Bez.
Is this OK, or is it bad?

P.S. If you don't have a spring lever but still hear those sounds when you pull, not to worry. It isn't the machine D.S

Oh yes, groaning and boinging on our Brunella both on up and down movement....sounds a like a creaky gate. This is the only spring that makes this sound and we have yet to figure it out but it seems just a complaint from Brunella and not anything of concern. A bit embarrassing when guests are about, but the good shots more than make up for it.

I already feel better.
Have tried letting a drop or two of olive oil down into the group, it helped a little for a while, but it couldn't remove all of the springy sounds. Maybe it is bad fat for the group? I tend to trust olive oil over most other oils when cooking or lubricating kitchen utensils, smells nice and all, that's why I tried it for the Bez too.

any chance it's calcium buildup in the piston?

Not build up in ours, we're sure of that!

There was a thread awhile back about sounds from a P.V. Lusso, and the solution was lubricating the pins. The sound doesn't seem like it's coming from inside the cylinder to us, just a bit mysterious...

Hmmm... mysterious indeed.
These sounds/vibrations travel quite effortlessly through metal, of course. On mine the sound seems to come from the handle and the cam part.

orphanespresso: lubricating the pins? What pins?
