zin1953, mock me as you may for saying I feel like a pioneer, but I still feel like a pioneer. With a covered wagon and an unknown grinder. Yeehaw! Maybe you're one too. So ok, you've had this grinder since the beginning. Great. But, it still has only been around for a year and half, and in the life of a product, especially a potentially good grinder, this isn't that long of a market life. From all the searches I have conducted, a wealth of information is yet to be written on this grinder. I took your advice and did a search in forums other than the Marketplace, but was unable to really find that much. I have only found threads that begin by asking for advice on the QuickMill, and by the end, involve mostly plugs for Mazzer and Macap without ever addressing the QuickMill. So, if you have a favorite posting, by all means, please link me to it. That's the kind of thing I am hoping for. Also, as of this posting, there are no consumer reviews on CoffeeGeek for the QuickMill:

I know I am not grinding too fine, because I am just setting the grinder to make 14-15 grams of 2-day old roasted coffee yield a 25 second double. And in that range of grinding, I hear the scraping sound. Actually, my ritual is to get 18 grams in the basket, knock the portafilter down twice, and then scrape it level, which then probably ends up being 14-15 grams. As I have written previously, a technician at Chris Coffee listened to my grinder over the phone and he heard the same sound of metal scraping. So, I am not crazy and there is still a degree of ambiguity here. Also, I would like to recall LeoZ's posting back from "Sun Aug 06, 2006 2:05 pm" which mentions the same sound/concern I have with the thing. Once he adjusted the safety screw to allow him to produce a properly timed shot, he heard the sound. This concern was never resolved in this thread or any other I can find. I got my grinder from a fantastic vendor, betterespresso.com, who gets her stuff from Chris. And when I got my QuickMill, the safety screw did not need to be adjusted to go fine enough, so it appears these are now being shipped with the ability to grind finer. However, as far as I can tell, these grinders make a metal scraping sound when grinding fine enough, and no one can seem to answer this. The technician at Chris Coffee assured me the sound was just fine, but all things considered, I think it is more than appropriate to try to rally for more information/experience on this younger grinder.
That being said, do other people's QuickMill's have a safety screw around the marked Zero so that it cannot be turned any further? Are you all able to produce 25 second 14-15 g doubles without hearing any metal scraping sounds? If you are, isn't it interesting that LeoZ and I have both experienced this sound? How do we explain this?
Just to clarify my experience with this grinder: for freshly roasted (2-5 days from roasting date) beans from Blue Bottle Coffee in San Francisco, I am able to achieve my 25 second 15 g shot in a range on this grinder between the marked Zero and 1.5-2 hashes finer than Zero. My shots taste wonderful, wonderful. This thing can do it. But, I hear the scraping starting about a half hash below zero, and that concerns me.
once again, any information is appreciated. Thanks to all who have contributed thus far.
I would just love it if Chris could make a reappearance in this forum to address this issue. Maybe I will call him soon and see what information I can get. Kim at betterespresso.com and Chris have been nothing short of the best customer service I have ever experienced, so I would like to know their opinions on this one.
I will be getting a Macap M4 stepless doserless soon, but I really want to contribute to the clarification of what is going on with the QuickMill. I may even keep the QuickMill as a dedicated French Press grinder.
