I wanted to chime in here and thank clonegts.  I did this mod to my Rocky and it works like a charm.

Posted September 6, 2004 link

It does work like a charm, and that is why I now wish I had not gone ahead with the mod... because I now see just how much grind is left behind !!!  I swear there is almost enough wasted grinds there for a "single" shot.  And what a mess I create trying to get these trapped grinds out.  I think I was better off believing I was getting most of the grinds out with the old tap and pulse method.

The worst part is that after you clean out the removable rubber boot and the plastic chute leading up to the rubber boot, your next grind will fill in the "clean" space you just created and you will come up short in grind volume.  I estimate that after each cleaning, you will need to drop in more than 20 grams of beans to get 15 grams out.

Someone really needs to develop a completely "vertical" grinder with the motor at the top, then burrs below the motor, then a very short vertical shoot.  I don't see this as being too difficult except that the base will have to be fairly wide to keep the top heavy machine from tumbling over.  In fact, this machine already exists in the Zassenhaus grinders... the only catch is that the motor is your hand and arm cranking on the handle.

It is amazing how much is left behind.  I tend to add enough beans for the day and then clean out the shoot during my nightly cleaning ritual.  I am not going to worry to much about the grinds that may only be a couple hours old (although I know that may drive some folks crazy).

I tend to do the espresso routine only on weekends or special occasions, and than only once or twice a day... so the "left behind" grinds is a real nuisance for me.  I am also pretty much a neat freak, but don't want to have to clean the machine after each use (i.e. lazy).

The problem with Rocky and other commercial quality grinders (for home use) is that they really were not designed for home use.  If they were, I don't believe they would trap so much grinds.  These machines are designed for many uses during a day, and so trapped grinds would normally not be a big issue.

I am seriously considering purchasing and using a Zassenhaus hand grinder for my espresso shots.  However, I have read that it takes up to 15 minutes to grind for just one shot... yikes.  Maybe I can dismantle my Rocky, remove the motor, and mount it on top of the Zass in place of the hand crank ?!?!

I use a Zassenhaus each morning for my Capresso CoffeeTEC and it takes all of ~ 3 minutes.  However, you can motorize a Zass for chump change.

I was well into the following project when this thread started. I guess this one would have been easier, but I am pretty happy with what I came up with.

When I finish it up all the way (trim long part off front, round edges, polish etc) I will give it a thread of it's own with a bit more explanation, but I think it is pretty obvious how it works from the following pics, and I'm pretty excited about this as it just got finished. It was easily the most ambitious sheet metal project I've ever attempted.

One more closer in, showing the completely unrestricted access to the grind path.

A happy error in design causes the hinged top plate to bind on the rubber tube. Luckily it just fits,  it keeps the plate from rattling, and keeps it open while cleaning.
