I might end up going with a manual grinder. This has some decent reviews -> "Zassenhaus Turkish Mill" I don't mind using a manual grinder over an electric one. Will keep reading reviews, but what are your thoughts?
I have just modified a De'Longhi EC310's portafilter. I used a 5 dollar saw I bought at the hardware store, cutting pliers and sandpaper. I sawed off the plastic part and the aluminum that used to hold the screw. Then I used the pliers to cut off the parts that the saw didn't reach. I evened out with the sandpaper. It turned out pretty good!
I'm using a De'Longhi 607706 filter basket. At least I think it is the 607706. The guy at the service shop for De'Longhis said initially that he didn't have the 607706 in store. But then he came with the filter basket that I ended up buying, and he said that it was just as good as the 607706, or maybe he said it was the 607706. I'm not exactly sure :) But he was right, because it fitted perfectly in the portafilter, when we tested it at the shop.
I have tested it a couple of times at home. I am using pacamara beans from El Salvador and a solid grinder. I am really satisfied! I'm clearly getting more crema, and I just like the thought of the coffee going directly from the portafilter to the glass, without getting contaminated with old coffee in the plastic parts of the original portafilter. This is also the reason I prefer the new all metal filter basket. I am thinking that in the long run, it will be easier to keep it cleaner than the original filter baskets. The latter have some rubber parts that will eventually absorb some old coffee taste, just as the plastic part in the portafilter.
My only challenge is what afelds mentions in this thread. The filter basket gets stuck in the grouphead after I have pulled the shot and removed the portafilter. I have read that this is common in other machines, even in professional ones, and it has to do with a few micrometers mismatch between the rim of the filter basket and the grouphead. It seems as if the filter basket gets sucked on to the rubber ring around the portafilter, something that does not happen with the original filter basket. The latter has also dents that attach it to the portafilter, which are lacking in the all metal filter basket I have now.
Have you found a way around this? If not, has this in any way damaged the grouphead? This is what concerns me the most. I have found a way to remove the filter basket with a cloth, and it's not problematic at all. So the only thing that worries me is if this could potentially ruin the grouphead sooner than would otherwise be the case.
I also appreciate suggestions about other filter baskets I could use that do not get stuck in this way.
By the way, maybe some of you have already done this, or thought of it, but I'm going to write to the folks at De'Longhi Braun Deutschland GmbH. Their e-mail is braunhousehold at delonghi.de As far as I understand, the offices in Germany are in charge of R&D. Maybe they are not aware about the fact that there is a big potential market for factory made naked portafilters for De'Longhi machines? They should be. It's just good if more people do the same. Then, maybe we get them to make a decent portafilter. I'll include links to videos and threads like this one in the e-mail I send!
Hi! I just wanted to comment that I tried a De'Longhi EC650 filter basket with a slight modification. These baskets have a squared flap on the outer part of the rim. This is where the filter basket attaches to De'Longhi portafilters that have a compatible opening. However, the EC310 machine's portafilter does not have a squared opening that is compatible with the EC650 filter basket. I guess that's the case for the EC152D, EC155 and similar models. The opening in the EC310 is rather round (like a semicircle). The guys at the De'Longhi service shop used a metal grinder to make the flap fit perfectly with my modified EC310's portafilter (naked protafilter). It works perfectly! The filter basket does not get stuck on the grouphead anymore! It also seems as if it fits better on the grouphead. At the same time, I feel that the shape of the filter basket allows for better tamping. Therefore, the flow of espresso seems to be coming out evenly from the filter basket, with a nice uniform stream towards the center. And yup, I'm getting more crema!
By the way, I also found out that a good way to remove a portafilter, that gets stuck on the grouphead, is just running some water through the grouphead by pressing the button. This is better than using force to remove it.
