    What's an rancilio MD 40 worth?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I'm going to look at an older rancilio md40.
    I'm able to get it cheaply.
    Not sure how old until i look at the actual machine.
    But it doesn't have the brown plastic, it got the blue one.
    (not able to find info on when the blue is introduced)

    It is definitely in some need of tlc, and i'm more then happy to give it some.
    Gives me a chance to learn more about the grinder.

    But after i'm done with it, i probably won't keep it as is an commercial grinder.
    And not really suited for home usage so i was wondering what is it worth?

    Nothing wrong with it as a home grinder mate, so long as you can clean it up, it works Ok and has plenty of life left in the burr-set.

    For your info, it is the same basic grinder as the Rancilio Rocky but not quite as flash...

    Hi mal, thanks for your reply.

    What's a good way to see/test if the burr set had plenty of life?
    And do you have any idea of the second hand value if it works properly?

    Our kitchen is small and the grinder has a fairly large footprint.
    So purely size wise i reckon it's not a keeper.
    But it doesn't stop me from having it temporarily and have some fun...

    I already had to sell my la cimbali Junior cause it was too big. ( i know....)
    And currently got the breville with built in grinder.
    Does the job just fine until we got a bigger kitchen.

    I picked it up today .
    It turns out not to be a md40, it's an md50
    An md50/at to be precise.
    And it's a big beast.

    im not experienced with burrs blades , but 'm guessing they are worn out.
    They are $50 new at coffeeparts.com so nothing mayor , but I am not planning of spending that much on them as it's really to big for home use.
    This beast is better of at a shop .

    There are some other small issues wit it , but nothing mayor.
    It definately has had some good usage.

    Ah yes, an MD-50 is a fair bit bigger than the 40....

    If you were going to hang on to it, I would have advised you to buy an OEM burr-set from a genuine Rancilio parts retailer, rather than a generic set. They are made from better quality steel and will last a lot longer.

    Basically, the best way to check if the current burr-set is up to scratch, is to just grind some freshly roasted coffee for espresso, and then see whether or not there are a lot of fines (dust) present. Burrs in good condition create very little fines. You could try the method of dragging your fingernail against the direction of rotation near the perimeter of the burrs, to see if the burrs are sharp enough to shave a little wafer of your fingernail off. Not a very reliable way of doing things though....

    Anyway, an MD-50 in working condition, cleaned up and serviced is a desirable enough grinder for any aspiring CoffeeSnob as it is quite capable of doing a good job, if you have the room of course. Maybe spruce it up and then list it in the 4-Sale section, someone will want it....

    Cheers,
    Mal.

    Are the burr sets on coffeeparts.com.au not oem?
    If not, where would i find one that does sell them?

    I done the 'finger nail test' and it does shave my nails, but more so on the inside.
    The more i go to the outside it won't shave my nails.
    But it does have some shaving capabilities so it's not all bad.
    Grounding coffee sound like a good plan but before i start grinding coffee, it needs a really good clean.
    It needs to be dissembled, and been trying to google info on how but have not found anything yet.

    I did find a thread on here about a refurb, but no info as to how, just some work in progress shots.

    I find when servicing grinders that the fingernail test is the most reliable assessment of the level of wear of the burrs.

    No marks on your fingernail = blades worn and require replacement.
    Scratch marks on your fingernail = blades worn but still serviceable.
    Scratch marks on nail plus bits of nail scraped off onto blades = nice and sharp, new or near new.

    It's important though, that people recognise that the area of the burr-set that needs to be sharp, is that section with the narrowest gap, just before the grinds enter the discharge chute. That section closest to the centre (or at the top in the case of conical burrs) doesn't really matter so much as this area is mainly for breaking the beans up before entering the fine cutting section...

    Thanks for all the feedback guys.
    I appreciate it.

    I'm currently in the process of dissembling.
    Got most bits off with exception of doser, as i'm lacking the tool to do so.

    While I'm on the subject of doser.
    When i use the lever to do one turn, it doesn't make the full turn.
    When giving the inside a little nudge it clicks and i can make the next turn.
    What the best way to go about looking for a solution?
    Is there a way to adjust this?

    Hey Dam,

    With the dose not clicking, mines doing the same thing. I think it's because the mechanism at the bottom of the doser is gunked up with old stuff and the grease has lost its lubricating properties and just become a greasy paste. I reckon that once this mechanism is removed, cleaned and relubricated it should be ok. But that's just my thoughts, someone else here might know something I don't and it might be some crazy Italian engineering feature (I mean, anyone worked on an Alfa before?) I had a laugh.

    I never thought of lubraction, thanks or that.
    I did have a fiddle and noticed that the centre moves if I stabilize that it works a lot better.
    Maybe that has something to do with it as well??

    Yep I would think so because if the main shaft isn't aligned properly the rest will be out of alignment too.
