    Using a car analogy, they both "handle" very differently when it comes to temperature management. And when you're dealing with a Pavoni lever, you must manage your temperature. I prefer the pre-M probably for no other good reason than that I have my "system" down better for the pre-M because I've had it longer and use it more. I'm sure that once I put in the time to master the -M, it would be just as good.

    I suspect that the wider hole will solve your problem... Based on the fact that when I cut out my own back in 2012 or so, I cut it to the full diameter of the bottom. I haven't had a single case where it ran down the handle.

    Here is a pic of me holding mine:


    Nowhere near as slick as what Gonzo did. No ridges. Just a simple cut straight down with a grit-type hole saw. About two minutes work.

    I should add that this is a pre-millennium 49mm group, using the a basket from an Elektra Micorcasa lever machine. I use those baskets in this Pavoni because they seem to hold about 2g more than the stock 49mm Pavoni basket.

    I have a newer style Pavoni as as well with the fatter group bell and 51mm diameter. This one I bought with a pre made bottomless PF.

    Anyway, based on my anecdotal experience with a full diameter cut in mine, I bet (hope) it solves your problem.

    -Peter

    (Sorry for the late reply) - Yup, mine has a lip - annoying that JB doesnt fix this if they're supporting LaPav's.
    Its difficult to find someone who can bore the opening wider in Melbourne. Has anyone had any luck and for those that have, how has it fared against rusting over time?
    I go to Perth for a month soon, once I'm back you're welcome to post it to me in Sydney. You pay postage both ways and the rest is on me. Because they're brass you won't get any rust, it will just lose its shine and will start to darken over time.

    Based on the picture above it'd be fine

    Yes, I agree, but removing the lip at the handle would remove quite a bit of the handle mounting too, and I'm not keen on that.

    Not sure if that request was for me or the OP, but mine has a lip, about 2mm.

    Can you pay a picture of the portafilter without the basket in it, specifically to show if there is a lip at the bottom or only the vertical sides of the PF left?

    Thanks Gonzo - what you've described is exactly the problem I'm having and thank you for the fix!

    If the machine is allowed to preheat the standard PF will be close to the temperature of the machine, very little cooling of the shot will occur.

    On the other hand I'm of the opinion that a bottomless will allow a greater cooling affect as the coffee has further to fall and has greater exposure to air.

    I had the OP's problem too when I converted my La Pav pf into a bottomless one. The coffee would regularly run down the handle. What was happening was that the coffee was getting onto the outside rim when the coffee was foamy and it was then running around to where the handle was and then running down the handle (because the handle boss slopes down)

    I did the following:



    I cut out the opening on the pf so that the clearance between the opening and the basket holes was large (about 5mm)
    I orient the closest line of holes so that they are perpendicular to the handle
    I cut a groove in the handle so that a ridge was formed on the rim, making it difficult for the coffee to go up into the groove and then down the handle.

    This all makes sense from an engineering perspective, but every now and then I still get dribbles down the handle.

    The reason I like a naked pf is that I want the shot to be as hot as I can get it, and the standard pf is a lot of metal to suck heat out of the coffee.

    I've owned and used a few Pavs but none using a bottomless p/f as I never really cared what the stuff looked like coming out, but how it tasted. I assume you are using a mirror as the contortions involved in managing lever pressure and keeping the thing stable all at the same time as peering underneath makes it a risky business to say the least.

    You haven't said what it tastes like. I suggest getting a normal portafilter and work on getting a typical lovely Pavoni shot and then have a squiz with the bottomless out of curiosity. Don't be surprised if you see multiple cones and a spritzer .

Thought I'd be and get a bottomless (the vids ive seen online make it look so easy to get a good shot) but rather it's proven to be more difficult. They're great fun to use but like you said, tricky to master. Guess i could give JBE a call or take the machine to someone who knows what they're doing with it

    Why did you get rid of it and what did you go to?
    Evening AnishC, I bought the Pav to use while having some work done on my Bezzera, then continued to use it when traveling, problem was we free camp a lot (no 240 volt power) it was just not getting enough use.
