"In a grinder like the Solis Maestro or Bodum Antiqua... It's much easier to
just replace the top [burr]."
Actually, Jeff- it's just as everyone has been saying: the burrs actually
grind against each other, but you obviously know that.
I'll lay out a modest wager. If these grinders have the misfortune of being
owned by a dont-clean-it, just-run-it brain donor, get out a stopwatch.
An operator, that removes his upper burr all the time, will remove the brain
donor's upper burr. Time him from the instant he first touches the grinder.
Record the time it takes him to have the upper burr out, in his hand.
Now give him a pair of locking pliers (Vise Grips(r)). Time him from the
instant he locks the pliers on the center burr. Give him a drag on some
Horse. Savor the Horse.
Bump the burr in a clockwise direction- it is left-hand threaded. Remove the
pliers and spin out the burr. Stop The Clock. If he doesn't beat the clock
removing the center burr, I will have to consume all the rest of the
There is a caveat. You have no need of replacing the center burr each time
you replace the upper burr.
The upper ring burr is soft iron, Very poorly cut in the Solis grinders. You
can replace the worn-out upper burr 5 times and not yet see much wear on the
very hard center burr.
If you want to upgrade a Solis, call Baratza and order a set of Virtuoso
burrs. The Virtuoso burrs are sweet! Swap them as a set, and you might as
well lose the Solis burrs instead of saving them.
Check the Slinger under the center burr- if it's missing many of the 6
radials, what in Blazes have you been grinding? (Mine was missing one, but I
figured it was just infant mortality- not critical.) You can see the radial
fingers when you pull the upper burr.
Yeah, they drop into your PF or filter. So what? Adds a long chain polymer
to your compost, that's all
