    Re: Silvia Showerscreen and Screw Conversion

    Hi Bill,

    Nice idea
    Id be interested to know if the new screw lets you dose a tiny bit more coffee without the extraction overflowing out the top/sides?

    Cheers,
    Paul

      Hi Paul,

      Well it does allow a fraction higher dose, but not by much. I havent had the coffee overflowing over the top/sides like you have. If thats happening to you, Id say the portafilter isnt sealing against the gasket properly, which would probably mean youve overdosed the basket or youre not putting the portafilter on tight enough. Is the portafilter tight to lock on? ie. tighter than when the basket is empty? If so, try dosing a fraction less.

        Silvias used to have a round head slotted screw (I have an older machine like this). I speculate that it was changed because the screw had a tendency to get locked in place and couldnt be removed.

        You may need the leverage provided by a socket someday when you cant get the screw to budge using a screwdriver.
        The replacement bolt isnt a slotted or phillips head but a torque/allen wrench head. It will probably have to have the coffee cleaned out of it with a tooth pick or somesuch but, as long as the bit is fully inserted, it should be easily removable with a bit on a screwdriver. If needed you can always put the bit in a ratchetwrench. If that doesnt work then it was put on way to tight to begin with! ;D

          Bill,

          I had problems with a stuck screw on my old machine and when I finally got it out it was quite rusty so I replaced it with a stainless unit. From your photo it looks like yours is zinc plated steel as opposed to stainless. If this is the case Id highly recommend a stainless unit to ensure you dont get any rust.

          I certainly like the profile of your chosen fastener! My Silvia has the older cheese head screw which isnt as obnoxious as the hex head but I fancy yours may be better than both, aesthetically at least!

            Hi Greg,

            No, its a stainless-steel screw. I got it from a specialist bolt supplier as I couldnt find anything suitable in stainless at the local hardware store.

                Beauty is in the eye of the beholder, I guess, but methinks it quaint that an object totally out of sight can be considered ugly. And therefore consigned for replacement. :

                Hmmm, there are a couple of ugly screws holding the baffleplate under the Silvia watertank. They have to go. Maybe a little number in chrome, SAE of course... ;D ;D
