    Hand Grinder

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi,
    I just got a Armin Trosser hand grinder today and admit to not knowing much about them.
    it has slight rust and i was wondering if any of you here have some good hints on best ways to clean it...is it necessary to take it apart, I am hoping NO!
    anyway, i will appreciate any suggestions you may offer.
    thanks

    Re: Hand Grinder

    Which bits do you want to clean? Rust on the top, handle etc?

    Re: Hand Grinder

    sorry, i should have been a bit clearer.
    slight rust on the top and handle, a bit more on the bolt connecting handle and top...going down inside to the burrs...
    so pretty much a general cleanup...
    any suggestions would be helpful as i havent done this before....and thought there would be some valuable hints here....

    Re: Hand Grinder

    Thats what I thought.

    As it happens, we (well my wife mostly) were just doing
    one tonight, after it arrived at the PO this afternoon.

    Following a hint from a friend (who is an expert in these
    matters) she used something very simple -- toothpaste
    and a toothbrush. Seems to work very well -- the grinder
    looks much better than earlier this evening.

    Re: Hand Grinder

    This might help, depending on the extent of the rust and the surface...

    Try wrapping some aluminium foil around your finger, shiny side out, and give the surface a rub, then rinse and dry thoroughly.

    I also recall something about rubbing a slice of onion on the surface once its been cleaned and can only imagine that the onion might have some chemical in it to help neutralise the oxidisation???

    Re: Hand Grinder

    there great tips, just what i needed to hear...i have actually used the toothpaste on something a long time ago but certainly did not think of it for this...
    as for the alfoil i came across a similar suggestion only it included using coke...
    so thanks very much i will give it a try,,,the rust does not look too bad...probably the bolt going down into the unit needs a bit more work...
    i tried the rice idea i came across in my search...and i can notice a difference with the burrs...only i seem to have altered the pressure now...and havent been able to adjust it again...
    i cant seem to be able to download a couple of photos which would have helped you with suggestions...

    thanks again

    Re: Hand Grinder

    If the above dont work you could also try some fine wet and dry paper (use it with some soapy water) available at any hardware store. The higher the number, the finer the grit, so suggest using 1800 or 1400 if thats not available.

    Most hand mills have an adjustment knurl at the bottom of the mechanism, hidden inside the box. If you remove the drawer you should be able to feel the knurl up inside the body of the mill to make adjustments.

    Re: Hand Grinder

    well it is certainly cleaner than it was, but still needs some work.
    i think i found the adjustment knurl but it is outside....part of the bolt going inside the box....is that correct,,,,that part is pretty rusty
    i havent been able to remove the handle, i did try last night
    hope this makes sense
    the handle is attached to a large bolt which goes into the box and is attached to the burrs.
    along the handle there is also another slightly smaller bolt which attaches to a 4 leaf clover shaped thing ( it has 4 holes) i think this part is what you called the adjustment knurl...

    sorry for this over simplistic attempt to explain...

    Re: Hand Grinder

    The adjustment knurl should be able to turned by hand Janine.

    I think the only way youll ever know if what youve located is for adjustment is to give it a slight turn and see if it makes a difference. ;)

    Re: Hand Grinder

    Yes a pic would be good!

    Quite often the adjustment is at the top. Im looking at one at
    the moment -- there is a disc with five notches cut into it threaded
    onto the bolt, a bar that goes into one of the notches and up into
    the end of the handle, above which is knurled knob threaded onto the
    bolt and holding the handle etc in place. I think this is what you have
    but with four notches. In that case, you adjust it by removing the handle,
    adjusting the notched disc, then putting everything back to hold the
    adjustment. Try screwing it down tight at first by having the burrs touch
    and turning with some difficulty; that should be just a bit too fine for
    espresso, but may be OK on yours. Backing off a couple of notches should
    be fine for plunger. Experimentation is needed!

    Lets know how it goes ...

    Re: Hand Grinder

    thanks to you to hazbean for all that info...
    i am pretty sure mine is like the one you described. i have sent the photos over to Dennis and he is going to post them here for me
    i am starting to work out how the thing should come apart...but i am not having any luck removing the handle at this stage...everything else (washers etc) i am able to move now. i think if i could remove the handle all the other bits will be able to be removed.
    good thing is i guess i am learning more this way....
    thanks to you and Dennis i have gotten this far, and am actually enjoying trying to take it apart now...yesterday, i didnt even want to go down that path.
    so thanks very much for your help...now dont go to far away because Dennis is going to post those photos...

    Re: Hand Grinder

    Here is a picture that I had on file of one of our grinders.

    Its an example of one that you adjust from the bottom -- a small
    lever underneath that you access from below, as Dennis described.

    The type that I mentioned above has the additional notched disc / washer
    below the handle, with the bolt threaded to allow adjustment. In those,
    the nut at the top comes off easily, as does the handle.

    PS you need to scroll the picture down as there are two combined

    Re: Hand Grinder

    yes, it is very similar to that one. i can undo the bolt at the top, which looks like the handle should just unscrew anti-clockwise. But it wont budge beyond a certain spot.
    it does not appear to be that rusted at all...so i dont know
    By the way, that is a very nice looking grinder, dont want to swap the little gem i have i suppose...only joking!!!

    Re: Hand Grinder

    OK, if it is like that one, there is no need to get the handle off for adjustment,
    as that will be underneath. My wife just mentioned that she has tried on
    another one to get the handle off (the nut is OK), without success due to
    the way its threaded.

    Yes it is a nice grinder -- rather attached to it Im afraid :)

    not about my generous offer to swap...

    Re: Hand Grinder

    I remembered that I read something about cleaning Trosser grinders a few
    months ago, finally remembered where. There is a report here from someone
    who succeeded in dis-assembly; there may be some helpful clues.

    See *http://tinyurl.com/4kxc7l

    (scroll up and down the page as there are a few relevant postings and pictures)

    Re: Hand Grinder

    Welll just thought i would let you know that the grinder is coming along really nicely....certainly much better than when i got it...
    last night i rubbed it up a bit with artist putty....it is a soft eraser that can be softened by molding it... very similar to blu-tac....
    anyway, it really brought the shine out...just thought i would share that, someone else may find it helpful...

    thanks again
