Been suffering through drip cofee Ack Ack but its fast. Took out my Proteo Romanza & fired it up. Found a new hand grinder A unmarked red & white with the Wheel on top cog. Two days & it still chokes the machine.
Been reading they have ceramic burrs now which I will look into Just wanted to play with my newfoun d grinder. Can anyone tell me how to dial into a good pull? Its too fine & is the slowest machine taking minutes to do 2 tablespoons.

Grind more coarse. Too fine takes too long or chokes machine. Too coarse and you get a fire hose through the grinds, just right gives you a nice shot. Adjust the grinder and be consistent in the volume of the coffee and to a small extent be consistent in the tamp but it is the least important part of the process.

Looks as if your grinder has a stepped adjustment (the notched wheel on the shaft) that's only in quarter turns. Loosen it up one quarter turn and check. With that grinder, it may be difficult to get some beans fully dialed in, since the adjustments may be a little coarse. It's possible to make a new little wheel that can double the resolution, so to speak, but if you're not a tool person, it can be a bit of a pain. You make a new wheel with 8 or 10 notches, tap the interior to match the threads on the burr shaft and make a new, narrower tab that will fit in the narrower notches.
I've got a collection of older hand grinders, mostly Dutch and German, that do a wonderful job of grinding for espresso, but not all older hand grinders are good for espresso. A good indicator is that it's marked for "Mokka" or "Mocca."
