Input:
Question: Why isnt there some kind of bushing to help steady the wobbly grinding shaft inside the hopper? There is no lower bearing or bushing whatsoever..
Document: The knob on the crank handle is loose and wobbly, the knurled nut that holds the crank arm on never stays tight and the plastic bars that help support the crank arm inside the bean hopper are flimsy. Overall I am not satisfied with this grinder.
I started reading all the reviews regarding the Kyocera's performance, and noticed they mostly focused on how it worked when coarse-grinding beans for a French press, or fine-grinding beans for making expresso, but my personal needs are in the middle. I use a Toddy cold-brew coffee maker to cut the acid content in my coffee. Toddys work best with the same kind of medium-sized grind as is used in a regular, drip-coffee maker. I wasn't sure I would get a consistent-sized grind without possibly needing to purchase and install the after-market lower bearing kit frequently mentioned in the reviews to obtain a good coarse grind for a French press.My concerns were unfounded!
From what I have read it works wonders. I have ordered one and I will update this review when it arrives. Go to the website for "Orphan Espresso" and look for "OE Lower Bearing UPGRADE KIT for Hario Skerton / Kyocera CM50 Hand Grinders". It will run you about $17 after shipping.Second:  The process of grinding is quite easy, especially on a course setting. It takes me about 30 seconds to grind 4 large tablespoons of coffee beans without much physical exertion. Some have complained about it being hard to hold onto but I can only conclude that they are doing it wrong or they have greasy hands or something.
I bought this grinder from Amazon to replace an electric whirling blade type grinder, and I'm happy with it. I use it exclusively for a French press, and I enjoy my little ritual every morning of grinding my own beans and making a superior cup of coffee.However, I did not realize until recently that there is a shortcoming with this grinder (and others that use the Kyocera ceramic burrs) until I found the Orphan Espresso web site. The problem is that the inner burr is only supported by a bearing at the top...there is no lower bearing so the inner burr does not stay concentric with the outer burr during coarse grinds.
It came with the hopper with the grinding mechanism, the glass jar with removable outer rubber base, a measuring spoon (which is small enough that it can be stored inside the glass jar) and a plastic lid that screws unto the glass jar for storing your coffee grinds.
this is very solid, have been using it for a year now with no issues whatsoever....the top part is plastic, but it is some kind of very sturdy almost ceramic like plastic......the finest setting gives you a good esspresso or mocca grind.....
The price of each varies occasionally, so, if you want this grinder, check them both out to find the cheaper one (here's the Hario Skerton: http://www.amazon.com/Hario-Coffee-Hand-Grinder-Skerton/dp/B001802PIQ/ref=cm_cr_pr_product_top).Check out these videos about the Hario Skerton, Kyocera CM-50, and the lower bearing modification for both:[...][...]If you decide to buy the modification, a 10mm combination wrench works for installing it (they don't say in the video).
Perfect for camping.- Very well made and sturdy.- In order to get an electric burr grinder with burrs of comparable quality, you will spend at least $200. Beware of cheaper grinders that claim to be "burr" grinders but inside they have a tiny useless burr sandwiched between spinning blades.Cons:- It's hard to keep it steady while turning the crank. If you try to hold it down on a table or countertop, the turning action will cause the grinder to tilt and wobble and you'll spill beans.
I bought the Hario Skerton (it's the exact same grinder just with slightly less opaque plastic) for my husband, a coffee connoisseur. Buying a good quality electric burr grinder was well outside what I could afford, but he loves this one. Here's the key though, if you, like my husband, use a French press regularly: get the lower bearing modification from OrphanEspresso.com. On the coarse setting needed for a press, the Skerton and the CM-50, without the modification, will give you an inconsistent grind.
This product actually has no function because it grinds beans so inconsistently that you are much better off buying your coffee ground instead of trying to use this.To explain simply, as you crank the handle the burrs move around so that some of the beans don't get ground up very well and others get ground much finer. This is because there is only one bearing support (where the handle engages). If that would have put a shaft through the glass so that the bottom could hold it into place as well, the unit would have worked fine.
Answer: It's designed to wobble. The wobble is what allows it to function without what ever your grinding getting stuck, even when you have it set to a fine grind. The side to side movement keeps different sized pieces moving down through the cutting edges. If it was fixed in place, you would have pieces that are too large not feeding through.
