It was only a matter of time before a commercial grinder joined the commercial two-group Grimac, and that time is now. 
I have acquired a used Cunill Space commercial grinder. Its a little-heard-of model, but very similar to most others in that catagory the Spanish Cunill maker produces.
Why get one? Because I can ;D ;D. And, seriously, because Mrs Robusto and I were becoming annoyed by the mess made by our Iberital Challenge doserless.
I have no qualms about the Iberitals grind quality: it is excellent. But even the mod of a cut up 2-litre milk carton to catch grinds hasnt stopped a few spraying onto the kitchen bench. Thats what happens when you updose.
And it does take quite a bit of time to grind 19 grams on demand. And when there is a houseful of friends and relatives anxious to get a good coffee, it was very time consuming.
So we thought we would go for a commercial doser grinder. And if you are going to upgrade, my motto is always go steeply upwards, never sideways.
After much research and seeing what was employed in cafés, our short list of candidates comprised Gino Rossi, Mazzer Super Jolly (new) and the Cunill.
The specs: 60 ml flat burrs, 610 ml tall, 2 kg hopper, 600 gram doser. Twelve kg, I think. It is big, but it does not overpower and still fits into the bench space to the right of the sink.
Af 445 Watts it is very powerful and so can grind effortlessly without overheating. The doser is ajustable from 5 grams to 10 grams.
Grind adjustment is a breeze and a pleasure. Very,very shmooooth. Just press down the detent button, grab the ring which is bolted via three small bolts to the top burr, and turn. Release the detent. Ah, no more RSI from the Iberital.
On the downside, being a commercial beast, it is a little out of its depth in a domestic environment if you only want to grind 19 grams for a double shot.
For the doser to measure out a correct amount, the mechanism has to be pretty much covered with grinds. And that means theyll go stale by the time they are used. Grinding on demand simply does not work.
Nor can you dump in 19 grams of beans and expect 19 grams of grinds --most of them would be trapped inside somewhere.
Did I say we wanted to eliminate mess :
Not yet. Havent perfected my technique, but its pretty messy. However, the potential is there. The portafilter cups neatly around a small chute under the doser. When I get my act together, it should be impossible for any grnds to stray.
There is no fork on which to rest the portafilter, but given that it will only be under the doser for a second or two, it may not be necessary.
Activation is through a rocker switch on the base. There is no timer (unlike the Iberital), nor is there a switch activated by pressing the portafilter against it. This is a doser model after all.
I dismantled and thoroughly cleaned everything of smelly old state grinds. Some parts were encrusted with them.
The sweeper which spins with the moving burr is made of solid steel. It does not extend far enough to the edge of the chamber, so some coffee is left on the walls, and on the chamber floor. I can see a simple mod about to heappen to fix that.
All parts were in excellent, as new condition. The top burr rests in a massive cast metal holder which is bolted down via 4 bolts. No freeplay in the moving one which of course is attached to the motor armature.
With the naked eye, the burrs seemed OK. But under a magnifying glass, the edges appear more jaggered than sharp. A new set is in order (should be about $40).
I have run out of beans to play with the machine and its settings, and todays freshly roasted batch might have to become a sacrifical offering. :-/
But with the burrs set so they just touch each other and then back off slightly, the grind setting still is on the coarse side, and the resultant brew awful --- so definitely will order new burrs.
LIKES: grind adjustment, slider to close off hopper, powerful motor, doser adjuster, solidity. Ease of dismantling.
DISLIKES: sweeping mechanism, necessity to load up doser.
Hope to post some pictures later.
