Hey all, this probably has been covered, but I just wanted to double-check. Is the IMS B662TH26M the right basket for Leva?

It's one of them, and there is also the deeper one b662th32m

It would be interesting to these those shots repeated with a puck screen in place.. and also to compare various showerscreens!

Most of the expansion occurs when the shot finishes and pressure is released. If you spend a very long time wetting the puck without pressure build up logically the puck could expand more before it comes under pressure There is a little device I've seen that prevents or limits the puck expansion. It was like one of the puck screens but with a height adjustable top part that would screw up and down and sit against the shower screen.

Ah, great. I think I would use 18g so that one should suffice. I saw that some people are saying that they can fit a 55 mm tamper in there? What do you think? I'm going to be manufacturing a new base for it.

I got both as they were cheap, along with the IMS 54.4 tamper. I think I'm going for a bravo tamper once the machine has arrived and I've settled on a combination that works well, so u can be sure it's the right size.

I would wait until the machine arrives tbh. The base tapers and the coffee will only fill about halfway so precise fit will be easier if you can try it yourself. I measure mine at 55.1 at the top but 54.75 about half way down

So I did a little test with the IMS B662TH26m 14/18g basket:

1. I measured 18g of my current espresso grind it to see how much room it would take before tamping. Photo 1 below.

2. The size of the heap shows that 18g is indeed the upper limit for this basket. Photo 2 and 3 below.

3. I use the 30-lb calibrated Espro 53mm tamper to see how far the puck would sit below the top of the basket rim. I measured about 4.7mm. Photo 4 and 5 below.

4. At the top of the 30-lb tamped puck and with the tips of the calipers inside the basket by 4.7mm, the diameter of the basket opening is 55.6mm. So if the tamp is harder / higher than 30 lbs, the diameter could be slightly smaller. The basket does appear to a very slight taper but at 55.6mm, there is some wiggle room already.

Obviously, grind size variation will lead to a different puck size. Hope this helps.

@SL01looking forward to hearing your thoughts on temperature settings. I like dark roasts too and will try the full roasts spectrum but it's nice to hear other owners' thoughts.

It's hard for me to believe that is espresso grind size, not that I dont trust you.

When I had the flair I would maybe grind that coarse, on the rest no really. A coarser grind compacts less, but if that is what 18g of coffee looks into the 26mm height basket, then there is no way you can add a bplus on it.

Before and after tamping, on the shitty grinder you see in the pictures.

Hi All,

There has been lots of conversation about tampers, and I've discovered finding ones that suit the nominal 54mm LSM baskets is a bit more challenging than with 58mm baskets.

I thought I'd make a suggestion, based on my very satisfying experience, to everyone who might similarly be looking. I suggest you look at Etsy.com. I purchased from a local Aussie maker on Etsy two custom tampers, hand made from jarrah timber and machined brass and stainless steel. Both custom sizes, 54.4mm for the standard Vesuvius baskets (hopefully they will be a good fit when I get my machine), and 54.8mm, which is a nice fit for my IMS baskets I have waiting. They measure exactly those sizes, the maker did them with a nice sharp lower edge, as per my request, and they look great and have a nice feel to them.

The cost - AU $50 each (~27 UKP, ~32 euro). Plus AU $9 shipping (within Australia).

So if you are hunting, have a look on Etsy to see if there are some local guys you can support, as well as getting exactly the right sized tamper.

Or send me a note if you are interested in contacting the Aussie guy I purchased from (I'm not sure if he ships overseas or not, but I'm sure he'll advise - he has been a delight to deal with).

Now I just need my new machine to actually use them. Hopefully soon.....

Dave

What beautiful tampers!

Thanks for alerting us to this, Elephantoplasty. I have just sent a message to Shai asking for him to make one for me too...like this one-

 

[MW11]

@Elephantoplastyamazing! The price is right too. Lots good stuff down under (I just bought a Tricolate dripper)

 

[Stevebee]

I put 20g of espresso grind, medium roast, into the 2 IMS baskets. Had 9mm headroom on the 26 and 14mm on the 32. It came just below the ridge on the 26.

Looking at this, based on the fact the group extends into the basket 10mm, I'd say the 26 is good for doses up to 18g, with the 32 for larger doses than that.

 

[Denis S]

Thank you @Stevebee this is really really helpful! Much appreciated. 🙏

The IMS tamper is a perfect fit on the stock ACS baskets, as close as a matched tamper/basket combo and much tighter than with the IMS basket itself. Go figure. The only downside is that it has a small radius on the edge, probably 0.5mm.

 

[MW11]

I read on the Izzo Alex Leva's thread on HB that people used the single baskets with the same grind size as the doubles!!. It was very interesting 🧐

Less volume = more shots during the day 😈

Would you say 54.7mm is the right size? Say yes and your dreams will come true

Duplicate post.

@DavecUK Can you give us the benefit of your wisdom as a super taster, and tell us what combination of basket and tamper you use please (and why)
