    Re: Filter Baskets

    I used a small fibre cutting disk on a Dremel tool. It took about 10 minutes or so to do a Breville double floor basket.

    Mrseca,

    Nice job! You can turn up my baskets anytime! Actually, you might run a little business doing this on the side for CSs.

    Its just a damn shame SB and the others dont just sell one ready to go (with small holes). Anyway, been using mine for a while now, and works a treat.

    Focussing on the perfect rosetta now!

    Hey TassieBean,
    I thought I was the first to turn off a basket bottom on a lathe, but you got in 2 weeks before..
    Damn you.
    Now that I have that out of my system, I have attached pics of the hole comparison between my modified SB basket and my Saeco basket.
    Saeco has twice the amount of holes and approx half the diameter compared to my sunbeam.
    Unfortunately the Saeco basket has an OD of 55mm and the Sunbeam has OD 53mm. Therefore not useable in my SB machine.

    With reference to your lathing experience.
    Also deformed the basket rim flanges a bit using the 3-jaw chuck,
    Most metal lathes have stepped face jaws, I was able to fit the jaws inside the basket and tighten outwards.

    as you try to cut into it, it tends to deflect away
    I used a toolbit with a 45degree point and fed it in super slow. Your attempt looks like you used a parting tool that may have been blunt.

    In the pic of the 3 baskets you can see I also attacked my single basket just for fun. It pulls an alright shot now.

    Here is my youtube submissions using the modified & non modified baskets.

    Also both hole photos are the exact same scale.

    hey...so seriously...where can I find a krups non-pressurised 51mm filter basket for my Sunbeam E3800 in Melbourne?

    Sixthly, the krups is a looser fit in the SB group handle, but not too bad, just need to be careful you dont knock it out into the knock box.

    Go buy yourself a new 58mm spring. Pop it in, should solve your problems. I know in the 51mm Breville handle that I have (dont ask why :P) it has a 58mm commercial spring in it.

    Thanks, nelo.

    I went and bought a second sunbeam pressurised basket (so i could keep the original for stale beans ) and stuck it on a lathe to cut the bottom off.

    Ive put a picture here for those interested. It turns out that it is not quite as simple as you might think, mostly because the basket has a springiness and as you try to cut into it, it tends to deflect away. As you can see, tried near the centre first, then further out, but finally, it worked best right out near the edge. Also deformed the basket rim flanges a bit using the 3-jaw chuck, so needed to gently tap them back into shape. The things we do...

    Yes, Ive backed off on the grind fineness and am now tamping harder. Still get a few grinds, but Ive decided I can live with it.

    Re: Filter Baskets

    Tassiebean,

    I have been playing with a new non-pressurised basket over the last few days at work. I have gone for the Breville Bar Italia basket, so I am not sure if the holes are different, but I found that using a Sunbeam 4080 it was important not to grind too small and spend more time getting the tamping right. This should minimise the problem of grinds in the cup. The slow pour would also suggest too small a grind. Once I found the right setting, I have been flying along with consistent 25 second pours from a pretty ordinary machine. Crema is good and consistent. I am using a crappy plastic tamper as the baskets are only 53cms, but if I hold it near the press and work carefully around the basket, it all seems to come together well.

    Good Luck.

    Re: Filter Baskets

    My first suggestion would be to cut away--the Sunbeam looks good from the top

    My old La San Marco had 53 mm baskets, and they worked well. Im sure one of the parts suppliers in the sponsors area could help. They might even be able to tell you if it would fit.

    Re: Filter Baskets

    Ok, to investigate the "grinds in the cup" problem, I went down to my local coffee shop (and bean roaster!) and looked at their baskets (obviously 58mm). Anyway, their holes are much smaller.

    So, does anyone know of a domestic sized (approx 52mm) non-pressurised basket that would suit a low-end sunbeam machine (i.e. 3800, 4800C, etc), that has smaller holes than the krups part number above?

    Ive seen where people have cut the bottom wall off the supplied double-wall sunbeam filters, and while this is a little agricultural, it may be where I head next..... :-?

    Anyway, are a few grinds normal or acceptable in a drink?
    No and no in my opinion.

    Re: Filter Baskets

    I should say that these baskets are for the low end sunbeams - this list might not be exhaustive - EM3600, 3800, 4800C, etc.

    Both are double shot baskets - although the krups has an inward "chamfer" so will be less volume, since both are the same height and diameter - maybe 14g versus 16g - I havent measured it, but it would be a small difference.

    Ill experiment with the beans.

    The SB basket looks like a double and the Krups a single.
    The ridge on the SB is new I think; the old 6900 baskets didnt have the ridge.

    The only way youll stop the grinds getting through the holes is to grind courser.

    For better crema you might need fresher beans. How sure are you about the freshness of the ones you are using?

    Re: Filter Baskets

    Thought Id add this here rather than starting a new thread. My Krups #0907163 unpressurised basket arrived a couple of days ago (about 2 weeks by phone order from krups notional spare parts office). I thought Id post a description and photo for those that are curious, then ask some questions.

    The first photo is the default Sunbeam consumer grade double cup pressurised basket (52mm diameter) on the left, and the Krups one on the right (as often touted here as being a good non-pressurised replacement).

    The second is a close up of the holes in each (same scale).

    A few of things to note. First, the sunbeam has a raised ridge around the top sealing edge, whereas the krups was flat. It might just be me, or something else, but I noticed I had to push the group handle harder to the right to stop the krups one blasting out at the seal. No big deal but something to be aware of.

    Secondly, I noticed straight away that the holes are bigger in the krups one. With my grind, I notice coffee grings in the cup after drinking it. No big deal either, but the holes certainly look bigger than they need to be.

    Thirdly, and most importantly, I am now getting a much longer pour. Those first few reluctant drops look wonderful. Certainly it does speed up during the pour, and I seem to have to allow it to continue well past "blonding" to get my 30ml from the double cup filter. Still getting better.

    Fourthly, with the beans I have (roasted recently, and ground immediately with SB EM480 before using), I am getting OK crema with the krups basket (yes, supermarket beans give NO crema!). The crema dissolves somewhat while Im steaming the milk, and by the time Im ready to pour in the milk, its beginning to look patchy on the surface. Im thinking bean type and freshness might be major issue here, but Ive more experimenting to do with fineness of grind, tamping, and bean type. Comments?

    Fifthly, the pucks with the krups are a delight! One little tap into my knock box and it falls out whole and dryish. With the pressurised SB, it was always a wet mush that took half a dozen knocks spattering everywhere nearby! The krups might work better because it doesnt have steep sides all the way down inside, or because it drains the liquid out better, or some other reason, but I like it!

    Sixthly, the krups is a looser fit in the SB group handle, but not too bad, just need to be careful you dont knock it out into the knock box.

    Anyone comments on any of this? Main questions would be amount of crema, and coffee grinds in the coffee. Should I grind less fine and tamp harder, or are grinds normal?
