If you own a Rancilio Rocky doserless coffee grinder, you sometimes might wish you were blessed with as many arms as Blinky is with eyes ... how else do you hold down the adjustment lever, turn the hopper and then also run the grinder when you're making the grind more fine? First off, let's cover why you should do this. Whenever you're adjusting a burr grinder to a finer setting, you're essentially bringing the burrs closer together. If you do that without running the grinder at the same time, you run the risk of compacting coffee beans in the grind chute and even warping or permanently damaging the threads. This is such a costly repair, it really means that you're looking for a replacement grinder. To avoid such horror, you need to run the grinder as you bring the burrs closer together. On the Rocky model that includes a doser chamber, this is easier, as you have an on / off button to use. The Rocky without a doser, however, simply has a rocker switch that must always be engaged in order to grind. So how do you manage all three at once? Watch Teri as she demonstrates her trick for adjusting the Rocky doserless more finely when you've only got your own hands to spare!
