For now, we are back using the old one and the new one is

Maybe it *is* worth fixing the old one, if the new ones are built
pre-busted.


For now we have a replacement from one of Krups' competitors
so that we can make Java until I decide which conical burr
grinder is the one for us.

I bet the sluggishness is due to dirty bearings or the like. Or
congealed coffee oils. A disassembly, cleaning, and oiling may be the
charm.


I looked into that. The enclosure snaps together semi-permanently
and requires a complicated jig to apply just the right pressure
to many key points to spring all the necessary latches for
disassembly.


I bet not. I open such things all the time, by a method akin to picking
a lock. With manufacturing tolerance, one of the latches will tighten
first. Open it with a probe, and the cover will move open slightly,
enough so the latch won't re-latch. Another latch will now be first,
etc. Use a taper or two to hold things apart between steps, driving the
tapers deeper whenever they become loose.


But I would return the busted new one, just to be a pill.


I suggested that. SWMBO reminded me that Amazon was not interested
in our petty concerns, though. Oh Well.


SWMBO is likely correct about Amazon. I would return it to the
manufacturer, who is supposed to care.
