Taken the liberty of editing your thread title. Hope it helps!

Regardless of the motives or affiliations of the makers of the video the fact remains that the Thunberg campaign has a lot of questions to answer. This they are not doing. Whether the campaign has merit or not is irrelevant if we don't know who is funding it.

It will depend on the make and type but almost certainly yes - porous to gas. You need something else. Might be cheaper, far more reliable and easier to buy bags with the valves built in.

My Niche cost me £350, half the price of your customised Mythos. I'd love a Mythos and it would suit me at least as well as the Niche. It might or might not do a better job and it would certainly last longer but for me, now, it's an economic no-brainer.

Possibly a silly question but... since the aperture in the disk is fixed in relation to the moving burr does or could this have any implications for uneven burr wear or perhaps more to the point sideways stresses on the spindle?

Agreed! 30 days should do the trick.

It would be just fine for a beginner. I'll echo dfk41's comments. I'm lucky enough to have a Niche and a 65e. These days, I mostly use the Niche. However, I do like coffee at the darker end of the roast spectrum.

Why not post on the Introduction thread and tell us about your coffee experience, preferences etc. and what you're here for, knowledge or just the ads?

As others have said, watch the video. But to answer the question, no you won't need to dismantle the burrs to calibrate. It's really easy and once done the markings will make more sense. Please don't obsess about the numbers. They are just an indication to help you. Everyone's will be different, at least marginally, since everyone's idea of exactly how much pressure to use when calibrating will be different. Once calibrated, the numbers will help you get repeatable settings for different beans etc. But bear in mind that they change a little according to the weather! (Literally!)

Happy holidays all!

I very much doubt the burrs are worn or "going". It's more likely to be an issue that for some reason the moving burr is going out of alignment when on coarser settings. I'm not sure how this could happen but it seems possible to me. Is it tight to the shaft or can it wobble?

Are you sure you have the burrs aligned as well as possible? It's a lot of trial and error to find the optimum. When you have the burrs touching, do they touch all or most of the way around evenly? If they only touch over a small part of a revolution you will need to improve the alignment.

It's sad. I've donated for a few years but I'm disinclined to do so now for all the reasons stated above. It's now a commercial enterprise and that has materially and seriously altered the dynamic. Now there is the whiff of commerce about it and I don't like that. I value and trust many of the contributors and contributions here (you know who you are) and some have led me to spend a lot of money.

The burrs should be OK for 100 kg let alone 10kg! It may need aligning. That is fiddly but the Orphan videos walk you through it. From the pics this is either a modded one or a later one. Around 30 turns should get you 18g of espresso grade grounds. It may well need cleaning. Other than that, I can see no reason why it would take 100 turns.

It's a while ago now but when I had this last I upped the dose to 20g for 35g out in 30 seconds. Didn't like it at 18g into 35g in 30 seconds. The grind needed to be finer to keep the time constant and we quite liked it then.
