Hopefully Niche is seeing this and get some ideas! 😊

@"MediumRoastSteam"#p23270 I have always been thinking they may be already working on the next iteration. I hope that would be a flat.

This from Sheldon (Sworksdesign.com) on the Decent Diaspora forum: Sheldon Wong sworksdesign.com On this current iteration - from perfectly clean inside, it ate about 0.5-0.6g on the first dose. I use a Mr. Puff regardless of the burr set and see about the same amount coming out but I don't feel RPM is an issue. I have no idea about longevity of the gearset though - gear reduction and motor torque seems sufficient so far. Alignment is what I want to focus (what little time I have) on to understand the stiffness of the whole assembly and what is achievable without shimming. What will worry me is tolerances between grinders - I wonder if Niche will tell me what their designed tolerances are 🤭

I would have to think that the next Niche will be a 54mm or 60mm flat at a similar price point. Crossing fingers.

you need to ask, does niche need to make a flat burr grinder?

@"Cuprajake"#p23293 'need' - probably not. Is there a market for a flat burr grinder the price of the niche? I certainly think so. Current options don't have the same reputation. The burr size is small for flats isn't it? Given there seems to be so much talk about bigger being better, is it worth it for you can't use larger burrs? I guess depending on price people can experiment without buying a whole new grinder.

64mm readily available and easier to make

I don’t have Niche. But, it appeals every one not just in terms of the price, the simplicity of its’ workflow and an easy switch between filter and espresso in the single dosing department. The solo and Eureka are there but they have issues. I think these are the reasons why folks may be keen to see Niche with a flat burr. But, anything less than 63-64 mm may not appeal.

All very well to say "I can fit flat burrs on the Niche…." But the real questions are: * Will it be usable? * Does it actually work? * What's retention like? * How long does it take to grind? * Does it stall? We all see some video of someone installing the burrs with some music on the background. I have't seen one of it grinding coffee…. :-)

Flat Burr Niche Mod

I’m guessing the flow control disc helps with the power requirements. How much is a Lagom or that Chinese thing (solo?).

MediumRoastSteam

LMSC Nope, unfortunately! It asks me to sign in either Facebook or instagram! :-)

You are right! - I’m now confused! it allowed me to watch the video earlier, but now it asks me to sign in.

No thanks! 🤣🤣🤣🤣🤣

LMSC

MediumRoastSteam Same here! Neither want one nor missed it. 🤣🤣🤣

Just for you x

Personally, I might give it a go IF the price is sensible, and it comes direct from Niche. I’m not holding my breath for that, though. Third-party adaptations? No doubt some will go for it, but that isn’t for me. I’m happy enough with the Niche as-is.

Rob666

For me, this defeats the object of the niche. A single dose big conical burr grinder at a sensible price. If I wanted a 65mm flat burr grinder, I’d just buy one. There are plenty to choose from. The niche is currently unique at its price point. 65mm flats not so much…

FadedFrontiers

Definitely not going to be a cheap solution given his porcupress is nearly 300USD but fair play to him for making it work.

Very impressive how quick it is to convert, building on the Niche’s great design there. My main concern would be motor and if this puts too much stress on it.

Cmon, does nobody on here want to be a tester?

dutchy101

Interesting development and it looks incredibly easy to do, but as others have already stated - this is not what the Niche was designed to do so I think I’d be wary of modifying it for this purpose if I had one.

Newdent

Assuming the niche components are up to the job, I think there would certainly be a market for a flat burr niche.

The DF64 isn’t close in terms of build quality. I own a DF64 and as an ex-niche owner, I’d definitely sell it for a flat burr niche. Great work by the designer and I’ll be crossing my fingers that it works out (though having seen the size of the niche motor and the plastic gearbox, I’m not too hopeful).

dfk41

Newdent The Niche motor and gearbox was designed for the Niche conical and the motor custom wound. Therefore, how can it be adapted on a diy basis for flat burrs ?

Newdent (though having seen the size of the niche motor and the plastic gearbo

Have you ever heard even one report of a planetary gearbox failing on a Niche. Remember always 3 teeth in contact with a planetary, which spreads the load. Only a single tooth in contact with spur gears. In fact the only person to ever bust anything in the Niche drivetrain, was me with a prototype. I worked on a fix with Martin to ensure it should never break in that way again.

Must be a 58mm burr, 64mm, I don’t believe will fit. Also IMO that particular wind of the niche motor, with the zeros planetary box has more than sufficient power and torque for those burrs…it will never stall.

The big problem is the speed of the burrs gives much less than optimal packing (coffee). Hence suboptimal results.

P.S. Advanced acetal gearboxes good, steel bad in that specific application.

Newdent

He says the smaller burrs are 54mm and then it looks like 58mm SSP multi-purpose, then some sort of 60mm standard espresso geometry burr (two screw holes).

SSP make all the fancy burrs in 58mm and 60mm and think that’s plenty big enough to produce great coffee. If Dave says the components are up to the job and the designer says he’s had no issues with the lower rpm then sounds like all systems go!

DavecUK

Newdent he’s had no issues with the lower rpm

for me the low rpm is a problem, as I said earlier.

dfk41

I thought all the ‘titan’ style flats that do very low rpm have problems, whether or not they get talked about is another matter

Cuprajake

dfk41 rise above it pal rise above it.

Posted a vid on a FB lever page, and immediately got a post from a bitter person, sticking the boot in

We just need to leave them to it. I just blocked the guy. CBA even talking to people like that. Don’t have the time or care tbh.

Newdent

AFAIK people with titans and variable speed are running them as slowly as they can get away with.

For filter, definitely grinding down at niche speeds.

dfk41

Newdent Does owning a Porsche make you a racing driver?

MediumRoastSteam

Newdent For filter, definitely grinding down at niche speeds

But not for espresso? Presumably espresso grind will be more demanding on the grinder than filter in terms of packing the burrs?

On something else: Hands up, I don’t understand the basic concepts, so I’m just speculating. But… if this concept of interchanging burrs was sooooo simple as swapping burrs… why companies like Kafetek and others don’t offer the option? Their grinders already have variable speed. Is this purely a money making exercise, where people have to choose and some even buy two grinders?

Although this mod doesn’t interest me as the burrs are too small, it is defo an eye opener and hopefully an inspiration for single dose grinder manufacturers.

Newdent

I think for espresso too yes but people definitely experience more stalling at lower speeds. People seem to use the lowest they can get away with and then others just use the middle of the range (approx 600rpm) because that’s what Hoffman used in his review… I’ve not heard anyone report packing of the burrs as an issue, more so stalling and that’s with light and ultra light roasts, softer beans are probably fine.

There’s talk of kafatek’s limitations being caused by the ‘off the shelf’ solution that was used as a speed controller but I’m no expert on that subject, just something I’ve seen mentioned.

DavecUK

Newdent I’ve not heard anyone report packing of the burrs as an issue

Well except me….

Newdent

Note that some burrs are better at spreading the cutting out more evenly around the burrs than others and certain geometries take smaller, less aggressive cuts so there likely will be geometries that cope well and others that don’t.
