Re: Rocky problems after cleaning
Replaced mine about 12 months ago after 7 years of use, made a world of difference, as you would expect. ;DOriginally posted by 79565F5D4A755956595F5D555D564C380 link=1255773927/16#16 date=1258758144Yep.. A good flat driver...
I thought I had burr issues and got a new set... two years on, they are still in the packet...
1: I give them a good clean every so often.... As in a wash..
2: If they will scratch or grab ya finger nail - check with ya finger and or finger nail like you would a knife blade... Then they are OK...
I have usualy found that it has been a bad batch of beans and be it stale or moisture or a bad roast... The beans are a pain when they get a bit soft... They rip and not grind.

Re: Rocky problems after cleaning
Trust me Ozzie, dump it, its just a pain in the rear end, have been running mine for 8 years without the guard, of course store it in a safe place so you can replace it if you decide to sell/upgrade.Originally posted by 796C6C7F737D79757E7F73160 link=1255773927/14#14 date=1258755557Thanks for the advice John, and yes I thought it would be a good idea to get a new set of burrs- nothing as good as having something new to compare against.
Your comment pertaining tot a good screwdriver is also valid- how many people spend a lot of money on good equipment and when they have to service them use, inferior tools, and cant understand why things go wrong??
I am contemplating the finger guard mod- I am just not sure if its function is only to act as a guard- does it not assist with th flow of beans into the grinding burrs as well. If it is just for protection, then it can go, otherwise may need to increase the height.
Cheers

Re: Rocky problems after cleaning
Good stuff Ozzie, once youve dismantled assembled it a couple of times its pretty straight forward.Originally posted by 7D68687B77797D717A7B77120 link=1255773927/10#10 date=1258753825Well, how easy was that?!
I followed the steps as per FRCN Espresso how to and everything is back to normal. Some lessons from my experience:
I presume it is the oils in the beans that form the greasy grundge that results in restrictions of bean feeder flow to the grinds, resulting in an erratic maybe hotter than normal grind. (my explanation for the bitterness tasted, as it is gone now). So clean that as best you can. Didnt want to try soap but a good scrub with a toothbrush got the majority of it off. Check for plastic pieces of the toothbrush- the grinds are sharp and slivers of the toothbrush may end up in your grinder and ultimately in your espresso.
When cleaning the hopper remove the finger guard- I shaked everything over the dustbin, and saw three screws disappear into last nights left overs- Could have been worse.
If possible clean the machine outside. There will be coffee dust all over. I havent got compressed air, so the close-your-eyes-and-blow method, worked but I had to clean up a considerable amount of potential lawn feed.
The flow of ground coffee after grinding can also be hampered by the oily greasy grundge, so remove the spout, the plastic guide and clean out the feed chamber.
A question- how do you know the burrs are worn? They looked sharp, but I can see some scuff marks on the cutting edge. I am also not sure what height they should be, to know if they are still ok?
Determining if the burrs are worn can be a little tricky, from memory theyre about $50 a set from Coffeeparts, as it is a 2nd hand machine, if you can afford it replace them, just a tip, when removing the screws from the old burrs make sure you use a good screwdriver of the correct size without rounded edges, the screws can be a little stubborn and you dont want to damage the slots.

Re: Rocky problems after cleaning
Hi AM
I upgraded to a Diadema Junior and Rocky, courtesy of one of the sponsors, 3 weeks ago. That was a step up from an AEG machine (similar to a Sunbeam that you can get at most department stores) and a Sunbeam grinder.
I havent changed much of late- Had a blend of Guatemala and Brazilian Bourbon that I made up a week ago. It is quite nice, but when the grinder started whirring, I found the coffee also tasted bitter. The again, I normal have milk, but with the wife being Lactose free have had to get used to Soy based Cappas in the morning- it could have been a new soy label she got.
Just had a shot and its beautiful, again. I am by no means a pro, but I can enjoy a good milk based drink after a few weeks of experience.

Re: Rocky problems after cleaning
Indicates to me that the beans are jamming in the finger guard area, get rid of the guard.Originally posted by 687D7D6E626C68646F6E62070 link=1255773927/7#7 date=1258750282(a light tap) it performed again.
Angermanagements mod would work just as well, my preference, for the reasons I explained in previous post, is to get rid of it altogether.Originally posted by 46696062754A66696660626A626973070 link=1255773927/1#1 date=1255774318With that in mind I modded my Rocky to allow the little mushroom to sit about another 5 - 8 mm higher... More freedom to shove the beans in

ANDOriginally posted by 564343505C52565A51505C390 link=1255773927/7#7 date=1258750282Have had a similar problem, hence my search that got me onto this thread. I have had my Rocky for about 3 weeks (2nd hand), and it did the whining-no-ground beans trick. After some conversation with her and a few choice words, gentle persuasion (a light tap) it performed again. But my coffee tastes bitter? I will go through the steps and see if it helps
Dont forget in most cases the problem will be PEBGAF...Originally posted by 605C554D58390 link=1255773927/8#8 date=1258751458give it a good clean following the instruction link provided by Angermanagement and all will be well
What makes you think it is the grinder.... What else has changed or what have you not changed when/after moving to a Rocky ?
1: What was your previous grinder
2: What Coffee machine are you using ?

Re: Rocky problems after cleaning
Rocky is a simple machine, give it a good clean following the instruction link provided by Angermanagement and all will be well, had mine 8 years, dismantle it and give it a thorough clean every few months, never a problem.
Oh, and get rid of the finger guard/mushroom thingy, about the only thing it does is impede the flow of beans and cause blockages, mine went a couple of weeks after I bought the machine, without the bit of plastic there it is also easier to see when the machine needs a good clean out (no the burrs wont eat yer fingers if yer dumb enough to try to stick em in there)
