Not sure how good these machines are or how much love they get but been having a flick through Facebook and came across this if anyone was interested [URL=https://i.imgur.com/xgejQHr.jpeg][IMG]https://i.imgur.com/xgejQHr.jpeg[/IMG][/URL]

hes in the lever group on fb from memory, theres vids there too

Do love the look of the machine but had no experience with levas.

fwiw its near the price of a new evo from memory and a new decent and a lm micra and a londinium lr24 so id not be paying that,

esp on bf [URL=https://i.imgur.com/mW0NhEX.png][IMG]https://i.imgur.com/mW0NhEX.png[/IMG][/URL]

@"Cuprajake"#p73690 where is bf? Seems that LM have stopped their black Friday prices. Looking for a used Mini rather than a new Micra, all depends what's available when my rebate drops haha

@"Cuprajake"#p73689 A linea isn't comparable to a hybrid lever in just about everything though and while a decent is super programmable, it offers the polar opposite in philosophy to a lever. The closest parallel is the evo which is also a hybrid lever but even the evo is quite different in its workflow and UI. I dont know who this seller is and i have no connection with the seller but the price of this unit seems to be about GBP1300 or thereabouts cheaper than a new nurri that has comparable specs? If so that is almost 30 per cent less than a new one so it doesn't seem too bad a deal if ut is still in good condition.

@"Jason1wood"#p73688 Begore i replaced it with a nurri a couple of years ago, I bought an izzo lever many years sight unseen without ever having actually used a lever before in person but from the get go, it was easy and straight forward to use. Having used levers, pump machines have had very little appeal to me ever since. So dont worry about never having used levers before, you should take to it like a duck to water. Despite its many capabilities, the nurri is at the heart of it still a spring lever machine with all the simplicity that entails, and eveb it's advanced functions are intuitive to use.

Just pointing out you can buy various brand new machines for the price of that used nurri Wasn't comparing any of them

If I want a used lever, I will look around for a used Evo 1. Terrific value for money as you may get it at a bit less than a half of that listed price. If new, I will get a Vostok or a Decent or an LM, if budget is not an issue. I have an Evo 1.

umm.

I am not sure what the spec shows but my Evo 2 outputs nearly exactly 20 ml per second over 30 seconds measured.

I assume this will be very similar on the vostok . Will that be an issue for you if you require 30 ml per second.

Coffee is great BTW

Adrianmsmith Well, there’s only one way to find out, heh. I like actually testing and comparing things, so I’ll have fun either way. Based on what I’ve seen, there’s a good chance it will give me more of what I like than the DE1 can.

Raja123

DavecUK I’ve seen your videos on the ACS levers, and recall you mentioning shot texture on that group being great. I think this is one thing some of us eventually work this out with a lot experimentation, finding a direct correlation with fill rates, pressure ramping, pressure applied over the course of the shot, group diameter, and puck depth, especially if we’re partial to espresso that has good body and texture. For what it’s worth, if I apply pressure even slightly more slowly, it can necessitate a 50+ microns tighter grind. That has quite a marked impact on shot flavor that can’t be dialed out with other parameters.

As Ive said a few times, my needs are atypical, so, I’m only providing my reasoning. What it means to someone else, is up to them.

Cuprajake

agree

levers are best of this, shame my dream lever came and then went, but when a machie breaks in the first hour you kinda loose all faith

the evo has and always will have made the best shots.

Raja123

Cuprajake I understand, Jake. I know I should have explained my reasoning better earlier. I was trying to be curt, and it didn’t lend well to the statement.

Adrianmsmith

Raja123

Pleasing to watch at least

If only the phone microphone wouldn’t make it sound like a tank which it really doesn’t!!

Raja123

Adrianmsmith yeah, builds the water column above the puck quickly, so it doesnt soak for too long before being fully compressed by the dual springs. The ramp to pressure shown in one of your vids is insanely fast. I can kind of do that manually to 9 bar on the strietman, but, I wouldn’t say I’ll be able to in the same way as the years go by, lol.

Cuprajake

id like to see the evo1 vs evo2 and the change in pump, iirc the gear pump is/should be quicker

Raja123

I have wondered for some time about the Matrix shower screens. The stack creates 1.5 bar of back pressure, which will hold the water back for longer during fill. However, they likely also impede max flow. Still, would be fun to play around with one and to find out how it affects the shot.

That kind of approach is mainly suitable for med-dark roasts, though.

Adrianmsmith

Raja123

Be aware, I modified my blind sleeve.

No longer a “standard safety system” although it retains a lot of damping compared to the standard open sleeve.

Mine has 4 × 1mm holes and to me it works fantastic now.

You could not do the 30 second test with 1 × 1mm hole as back pressure would trip the pump as it hit set point for “ pre infusion ”

You also dont get the same full flow shower as on video above.

My current set up is great for me and allows 19.5g with the acs puck screen in the acs 32 basket.

54.4 tamper

Noone that matters will agree but it’s an improvement for how i want to work with it .

And if the impossible did happen, i.e i knocked the portafilter off id rather be hit by the lever then, than with an open cylinder 😎

Has anyone actually ever done that?

Raja123

Yes, I’ve seen the holes you drilled. I had ACS measure the fill rate, and was told it’s 22.5ml/s if the pump is set for 6-bar. I’m sure I’ll have to experiment with it for a while to work things out for certain shot styles.

I’m just counting down the weeks, but the wait is actually useful; the adjacent room is being renovated, after which the room for my office can be painted, and I’ve just found a carpenter to make the coffee bar that I need for the machine. Lots going on over Xmas.

Adrianmsmith

Raja123

Is that with the blind / safety sleeve or the standard open sleeve fitted.

Raja123

They didn’t specify.

DavecUK

I suspect it might be with the safety sleeve, I would expect without the safety sleeve the flow/fill rate would be even faster, the pump has a good capacity.

Cuprajake

I asked on the discord app the de1 can hit 12mls

Raja123

Cuprajake Whoever said that is quoting the number it can/could be set to, rather than the actual output it can achieve. In reality, most machines top out at 8ml/s and a few go a little over (depending on AC mains voltage), but nothing known out there hits 12. Decent were recently considering lowering the max value that can be set, because it is misleading.

A recent post from Colin (works for Decent Support) confirms this:

I also went and read the Discord - here is the last reply to you from Rohan:

Cuprajake

when i ran tests myself on a fast profile i think mine topped out at 7mls

Raja123

Yeah 7 to 8 is the normal range. There are a few guys in Asia that can only get 6, due to the mains voltage there.

Adrianmsmith

Raja123

Grind finer…

Oh no, this isnt facebook is it😎

Raja123

Adrianmsmith lol. On that subject, I’m at 280 microns of burr gap (80mm lab sweet clones in Fm grinder) for a mere 12.7g dose that gets hit with a declining 9 bar profile. Small group diameter and quick compression really helps, but don’t tell the fb crew that!
