That reminded me to report on the Virtuoso and the valuable service
the company provides. My six month old refurbished Virtuoso stripped a
gear and quit. I called Baratza and was told that they would
immediately ship me another grinder and that I should use the package
to return mine. What could be better? Well, I thought we might do
better than ship two such heavy grinders across the continent, so I
suggested that he just ship me the gear and that I replace it, thus
saving us both money. He went for it and two days later I had the part
in hand.
The repair went smoothly, but I hesitate to recommend it to everyone.
Here is why: You might have difficulty getting the old gear off. You
could forget that the nut on the center burr shaft has left hand
threads. You could easily forget where some of the washers go. You
might easily over torque the screws which hold the motor and grinder
assembly to the chassis. (What are they...3 inch-pounds?) You might
easily reverse the wires to the dc motor and have to reposition them.
You might have to readjust the zero clearance position of the grinder.
Oh, and you like detentless adjustment? A clean shop can help you find
that little black tang. Leave it out and you'll have no clicks.
When finished you might have a thoroughly cleaned grinder with epoxy
putty reinforced bosses in the chassis where the motor assembly rests,
or you might have a basket case. Unless you are very handy, you might
best take the swap offer. On the other hand, if you do it yourself,
you'll know what you have and you won't have missed all the fun.
When the day comes to swap burrs, similar adventure awaits. Only next
time you might try driving the shaft out of the gear instead of
cutting it off with a Dremel tool. My burrs still look and feel like
new ones and the thing sure does grind uniformly. The adjuster clicks,
too!
