    Iberital Maintenace

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Seeing were all into grinder maintenance, has anyone attempted to dismantle the conical burrs on the Iberital? The problem is removing the nut which holds on the top burr --- turning the nut also turns the motor shaft on which it sits, defeating the purpose.

    I want to remove it to give the burrs a thorough clean.

    Try and see if you can jam a screwdriver in via the coffee exit chute to keep everything stationary- will give you some leverage if it can be achieved ;)

    Thanks for that advice. However, Im seeking to avoid having the burrs chewing on metal. I was hoping there is some secret and more gentle way.

    Use something made of wood or plastic. Try a pencil or pen and see how you go.

    Hi Robusto,

    I used to own a Lux grinder, with the same burr-set as the Ibertal. In all the time I had it, I found that just setting the grind to a coarse setting, adding about a quarter of a cup of uncooked rice then letting rip until all the rice was exhausted out of the chute, did a great job of cleaning the rotating burr (the stationery burr and everything else inside for that matter).

    All this left for me to do occasionally, was to then just remove the stationery burr carrier and get stuck into all crevices, nooks and crannies with the small nozzle attachment on a vacuum cleaner and it came up beautifully clean, and with a minimum of fuss and bother :). I think the less often you disassemble the component parts of a machine, so long as its consistent with being able to maintain it properly, the better. Unnecessary disassembly and reassembly will ultimately run the risk of causing more problems than it solves....

    Cheers,
    Mal.

    Tried the rice -- came out very nicely. Many thanks Mal, saved me potential damage to the burrs through dismantling.

    As a bonus, we now have a way of milling rice if ever the menu calls for it!

    Re: Iberital Maintenace

    Gentlemen. A little advice from left field.

    There is absolutely no need to dismantle coffee grinders and get into the burrs unless the burrs require replacement. In domestic use this is a rarity.

    I wouldnt put anything other than coffee in my coffee grinder, otherwise you could end up with the residue from the cleaner material in the grinder, instead of coffee grinds!

    If you wish to clean a grinder, use a small artists brush and use it wherever it will get into. Then use a vacuum cleaner from either end of the grinder ( ie inlet / throat end, or outlet end) to suck all the dislodged grinds away.

    If this is done often enough the left over grinds wont turn into an oily paste, and nothing more will be required!

    For the rest of it...wipe it over with a clean soft cloth.

    Regardz,
    FC.

    Re: Iberital Maintenace

    Going back to my previous life as an electric water pump repair guy, if the burr is at one end of the motor spindle, look at the other end of the spindle for 2 opposing flat surfaces that a shifter can hold still while you remove the nut - after all when assembling it, the installer (machine or person) has to hold the shaft still to do the nut up.

    Otherwise if the shaft is round, try using vicegrips (those locking plier thingys) ONLY repeat ONLY repeat again ONLY if that surface is not in contact with any other surface when the machine is assembled - ie that part of the shaft is not being used as a bearing surface.

    Obviously dont force anything in case the spindle bends.

    Caveat: This is only advice from me, the best thing about advice is you dont have to take it.

    If you stuff it up, your fault not mine ;-)

    Hope I havent scared you off

    cheers

    Re: Iberital Maintenace

    Is there any chance the burr is held on by a left hand thread?

    That might be easy to check. If I were designing something like that, Id look at the way the burr rotates and use a thread that tightens the burr when subjected to vibration.

    A lot of cars use this method on engine cooling fans. One loosens them by undoing the nut in the same direction as the item rotates.

    So, if the item rotates anti-clockwise (viewed from the shaft/threaded end), undo it in an anti-clockwise direction (RH thread).

    If the item rotates clockwise (viewed from the shaft/threaded end), undo it in an clockwise direction (LH thread).
