Posted Sun Sep 20, 2009, 2:30pm Subject: Kyocera hand grinder - Can't get the setting to stay put

I recently got the Kyocera hand grinder from OrphanEspresso, and i'm having a small issue with it. I'll usually start off at 1/2 turn from the tight setting for espresso, but by the time i'm done grinding, the setting has moved and I end up getting layers of grounds from fine to very course. It seems like I cant get the little adjustment nut to stay where I set it. Has anyone else had this problem, and is there a solution? Is my grinder just defective? I also just sent an email to OrphanEspresso and asked their opinion, but i'd like to see if anyone here has experienced this.

Hi, I was considering purchasing one of these grinders.In my research I came across a thread on another site that describes some issues some people were having with the grinder as it got older and some work arounds.I would wait to hear back from the vendor before doing anything to it.If yours is brand new it may indeed be defective.If it has been in use for a while it may be just normal wear issues that these people are also experiencing. http://coffeesnobs.com.au/YaBB.pl?num=1250594325 Good luck.

After a few weeks of use, I had the same problem with the grind getting coarser and coarser as I ground.

I had a chat with Barb from Orphan Espresso. She gave me a couple of tips, but the grinder still keeps getting more course during the grind. She said I may just have to return it so I think that's what i'm going to do. I'll probably just splurge a bit and get a Baratza Vario from them instead.

That plastic knob that is used to set the grind doesn't have defined enough indents. I "fixed" this by taking a dremel between the somewhat raised lines. I did this even before I used it as I could see this was going to be a problem from the get go. I'm actually in the process of having a new nut made out of aluminum with well defined knotches. Once I have it worked out and to my liking I may sell them on a made to order bases.

Sounds like that would be very useful. Maybe you could even partner with Orphan Espresso and sell them there.

Posted September 21, 2009 link Since bringing my La Peppina in to work, I'm using the Kyocera CM-45 CF for a grinder. I'd been using this with my Twist but would like to improve the ability to set the grind for use with the La Peppina. Beyond this post, I'm having trouble finding any good mods for the CM-45, I'm getting hundreds of search results, let me know if you know of any good mods or have pictures of what you've done. Thanks.

I've cleaned up the grinder and burrs and stretched the spring a bit which seems like it would help, but I'm still looking for mod tips. Anyone use a second spring or double nuts on the Kyocera? Anyone know the thread size?

I actually did exactly the same thing (but after a month or so of use) with my Porlex (whose mechanism is almost identical to the Kyocera) and this works like a charm. I also made the groove (the ones in front of the raised line) slightly deeper.
