Tried reaching back out to Knock several times and have received no reply. I assume they could not be bothered in the hassle of providing a replacement part. Anyone have one they would like to part ways with?


What was the problem with the handle? Mine had the knob screw off, but I was able to screw it back on just by creating enough friction with the knob against the handle. I then backed off a few turns and used Loctite. Been fine since!

I assume the knob can be pried open to get access to the pivot/bearing, but I couldn't for a spudger in and forcing friction solved the problem.

Best setting for V60 seems to be 3.2, so espresso should be in the neighbourhood of 1.6, they are usually in a 1/2 ratio for all manual grinders I have.

How do you know when the grinder is at the zero point as I dont want to fully lock the burrs incase of damage, am I just being paranoid? Someone please enlighten me! :D

The burrs damage occurs if you force turning when locked.
Just touching the burrs does not damage them.
So feel free to adjust them until they lock, note the setting as zero, then release until move freely, at least half turn. If they still rub after one full turn, I would consider unacceptable miss-align and return for service.

With the Portaspresso I'm at 1.3 - 1.4 with normal beans (light to medium roasts) and down to 1.1 with decaf

After numerous emails I have been told that a first generation handle is not avail. Can anyone be so kind as to provide me the dimensions of their handle so I can try and reproduce one?

Hi,

Does anybody know the diameter of the drive shaft? Is the Aergrind metric?

Thanks,
Klaus

I bought an Aergrind directly from Knock and experienced no trouble at all with follow-up emails & getting a response. The grinder shipped without delay. Peter was prompt & courteous & helpful each time I emailed Knock.
