Thanks for sharing. A question if I may:

You said a few times in the video the grinder uses a 5mm thread pitch. Is this actually correct? Or did you mean .5mm?

I'm also not sure how that would work with your stepped ring to also allow for .005mm adjustment. As a 1˙rotation would be about a .014mm gap change. Thus my question.

Cheers!

From the LWW website:

"The locking ring which is part of the EG-1's grind gauge mechanism has 100 gradations and allows for 5µm (micron) adjustments per mark"

That would correspond to a .5mm thread pitch, as you suggested. Craig likely just misspoke...

A 2mm-burrs gap would correspond to a coarse french press grind. So yeah, 0.5mm pitch makes sense and 5mm doesn't.

They have a typo on the site and Craig simply mispoke. He said he was slightly nervous in front of a big crowd.

Thanks Chris for the video! I think i'll be joining some of the rest in the occasional re-watching of it while waiting!

how loud does it compare to an EK when it grinds? The video shows when empty, so perhaps you have an insight when people were grinding stuff?

thanks again!

So the 10 seconds they refer to in the video must be based on a specific RPM. Or, did I miss something else that Craig said about RPM and grinding time?

I'm not quite sure about that to be honest. I didn't even think of asking him that question, but it's a good one!

Thanks for the super informative post! Did the barista need to use RDT/WDT to get good results?

No RDT/WDT but don't ask me what the quality of the shots that were pulled as it's not exactly my specialty. The new shaker seemed to work incredibly well, though, as Tom has mentioned.

It was a little hard to tell in such a big space with a large crowd, but it seemed to be exceptionally quiet! I would say it's a little quieter than an EK43 when nothing is running through it (to be fair, the EK motor is a fair amount larger), and - from what I recall - it's quieter than the EK when grinding, as well, but that might be a better question for Tom to answer since he used both side-by-side and in the same environment. I could be wrong, but the construction of the grinder seemingly isolates noise quite well. I definitely wouldn't hesitate to use it in the kitchen while my wee one is sleeping upstairs, if that counts for anything!

I'm glad everyone enjoyed the video none the less! It was truly a wonderful experience, and - like all of you - I simply cannot wait to get my hands on mine!

From Lynnweber.com

"The EG-1 utilizes a burr carrier with a 1mm thread pitch to regulate the distance between the two burrs. As the distance increases or decreases, so does the coarseness or fineness of the grind."

Chris,

Thanks again for all this info.

On the video, Craig talks about the "clicker" that is located near the chute.

Excuse my ignorance, It's the first time I come across such a feature. Would you be able provide more info about it? Is it desined to be used each time you grind? With and without RDT?

Thanks
Macphi

I didn't upload this to Youtube, but here's another short video for another reference point on the low rpm grinding/volume level.

Thanks! sounds good!

I'm trying to understand how burr alignment works on the EG-1.

From the picture on their website (http://i2.wp.com/lynweber.com/wp-conten ... =720%2C720) it appears that the lower burr is rotating, thus is attached to the motor drive shaft. The lower burr also seems to be what gets moved when you loosen the Bearing Mount.

If this is the case it seems while doing burr alignment you would be moving the Bearing Mount, the lower burr, the drive shaft and the motor since they are all connected.

Am I missing something here? Perhaps they have some sort of flexible shaft coupling (e.g. http://www.lovejoy-inc.com/products/jaw ... -type.aspx) to allow the lower burr mount to move slightly, independent of the motor?
