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.

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).

    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.

      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!

        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.

          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.

            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.

              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.

                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.

                DavecUK well you’re more anticipating an issue than reporting an issue. I’ve not seen issues related to burrs not packing, how does that present itself? To me that sounds like coffee not feeding properly or have I misunderstood?

                  if you do a side by side (as I have done) between the original Mythos One fast spin and the Clima Pro slower spin,I found without any reservation at all, using taste as the only indicator, that the faster spin produced a far nicer taste in the cup than the slower spin. Indeed, if ever I go back to a Mythos I would definitely buy the older variant. So, does that translate to other grinders? To keep it simple, as I understand it, the burrs need to spin at a certain speed in order to ‘throw’ the coffee out. On a Mythos because the burrs are set at a 45 degree angle then there is only one way for coffee to exit, but one a true flat position burr, in order to exit you either need to achieve a certain minimum spin. The only conclusion I can draw, and it is probably wrong, is that using a flat with a slow spin, then the coffee is not going to exit as soon as it is ground……but someone may be able to pick fault with what I have said

                    dfk41 In fact it’s even “worse” - particularly in a single doser (like the Niche) with flat burrs mounted horizontally, there is nothing that pushes the grounds through the burrs other than centrifugal force. The slower the rotation, the lower the force.
