Advice on naked portafilter conversion

If your remove the basket and the inside looks like the silver is coming off / yellowy-brown it's probably brass.

Thanks for the tips rawill and level3ninja. I’ll pass it on to my partner and see what we can do. If I get stuck I just might take you up on that offer level3ninja. Just not sure what this portafilter is made of at the moment. Another thing to investigate.

I just used a hole saw, and did it slowly with a battery drill, no dremel, just little sand paper afterwards to take off the sharp edges, worked perfectly on the brass ones, not so good on the aluminium one as the hole saw kind of "dug in". I guess because the metal is so soft. Didn't make a big mess, but I was not happy with the job. But of course it still works fine!Originally posted by empty123 View PostUnfortunately I am not handy with a dremel or any sort of tool. Will have to ask my partner to do it, but not looking very likely as the list of to do’s is a mile long and this machine is starting to show signs of pump failure.

You're welcome to send it to me if it's brass (or at least not stainless)Originally posted by empty123 View PostUnfortunately I am not handy with a dremel or any sort of tool.

Yes rawill the EM5900 is rather temperamental, isn’t it. I find it very good for the price though; I honestly did not expect it to last this long (nearly 6 years now I reckon). Prosumer machines would probably be more consistent and long lived, but for $180 over 6 years I am not one to complain. If anything, I have learned a lot about grind dose tamp from this machine and that would certainly have paid for it many times over by now.

I am sure you could get a "spare one" off an auction site or similar and cut the bottom out as I have to 3 of them now.
Interesting, I often get a block, or a gusher, trying to get my 5600 to perform as I want it to!
More work required on grinding and tamping!
I have a couple of nice ones, chrome plated brass, and a cheap light weight aluminium one, not nearly as nice as the heavier one.

I’ve bought those baskets before and I think they’re called Breville BSWF100 officially. I use a 51mm krups basket in my trusty EM5900 and they have a slightly different shape. Nice shot of your extraction there. I’d like to modify my PF into a naked too.

Yes there is a supplier in Australia that has the Breville baskets in a pack. The single shot and double shot single walled versions.
I have bought parts from them. There is a double single walled basket on Ebay. I use the Krups and the double I got from Ebay in my 51mm P/F.
Made a huge difference over the double walled baskets that came with the machine.
And donated the Breville ones to my daughter to use in her little Breville Bar Vista, paired with an EM 480. Not sure donating them to her was the right thing to do.
The Breville ones might be as good as the Krups and Ebay one. I can't tell for sure.
All with a naked P/F.
In my view the only way to go to get your techniques sorted out.
Soon daughter will get a refurbished EM 6910 from me.
My old trusty that has done over 10,000 shots.
Now with a new collar.
Love that shot of Leroy's above, looks excellent to me.

Yeah they’re all called ‘51mm filter baskets’. Usually the Breville ones aren’t too hard to find although stockists seem to run out of stock frequently. You usually have to buy it as a set with the 1-cup basket. Krups, Saeco, Pavoni ones can be found on eBay or possibly via parts suppliers like Coffee Parts. Whatever you get it’s worth doing.

hi LeroyC
I was making all sort of mess back when I had still had the Presso..never thought it was the basket! But it was probably more my technique
Its funny that since using the modified portafilter in the La Pavoni , the 4-5 shots I pulled so far have been fine, not mess at all. It might have been my technique have improved, or that I am using fresh home-roasted beans.. The only other variable I can think of is the grind consistency, I am currently using the Rosco hand grinder which produces much better quality grind then the old Sunbeam I previously used.
But you do make a valid point, if my technique was right I shouldn't have to cut the hole bigger..... now I have to return all the files and attachments I bought in excitement from Bunnings yesterday...
However, I am also interested in trying out the Breville or Krups basket you mentioned because I do hate the ridged design of the original basket. Are they both 49mm? Which part no.or machine model should I search for? just dont want to order the basket with so many variations.. the La Pavoni Millenium i have is suppose to be 51mm basket.. and yet it fits in the Presso (just)..but the Elektra MCaL 49mm is a very loose fit. I am guessing Breville one should be more accessible in oz?

I did something similar with a Presso naked portafilter to fit my little Bialetti espresso machine. I had similar problems with drippy, messy shots until I changed to a different basket. The basket that comes with the Presso portafilter is absolute rubbish and I haven’t used it since I switched it out. When you think about it making the hole in the portafilter bigger really shouldn’t be necessary if you’re getting really good extractions. So before you get the file out again I suggest you try a different filter basket if you haven’t already. The two filter baskets I’ve used successfully are a Breville single wall, 2 cup filter and another one that’s slightly deeper that I think is a Krups or it might be from an Isomac Viper or something. Anyway, looks like you’ve made a good start, hope this helps a little.Originally posted by justacuppa View PostReporting back, I have success converting the portafilter to fit my La Pavoni [emoji16]. After not making much progress with a tiny file I found in the toolbox , I saw an opportunity with a piece of low grit sandpaper that was sitting on the table. Holding the portafilter and rubbing the lugs against the paper on the table was a much easier and faster process. The portafilter is made of stainless steel so still took some effort and I still need to sand down the sharp edges around the lugs. I have yet to file off the bottom opening but I already made a shot this morning and the results look good.
Might be just my lucky day but there were no squirts and no mess with coffee dripping down the handle. Blonding didnt occur till very end of the pour so the resulting cup using the Ethiopian yirgacheffe was very nice.
I will post some photos up later when I get home.

That sounds like got that one just right.
Now all you have to do is make it repeatable.
If you can do it once you can do it again and again.
