    ...how fast does your Yamaha grind coffee?

    (I am picturing quite a mess and expect you are related to "Tim the Tool man")
    probably just a fraction quicker than your new climax...nice pick up

      May not be all bad, looks like that large gear is replaceable, may have been designed to be the weak link, to save worse damage to the motor.

      Usually with electronic gear it is the other way around.

      I have seen a $10,000 communications controller turn into a bar heater just to save a ten cent fuse.

      But then comms controllers are not much use, they cant grind coffee

        Hi all
        This morning I had a stone in some beans for the first time. It was some Costa Rican Tarrazu which I had bought already roasted. Here is the story ...

        My wife knows everything. When I mentioned that this Tarrazu originates in Costa Rica she suggested that the soil was probably from the Arenal volcano.

        Its pretty impressive.

        Later that day the grinder made an awfull noise and I turned it off immediately. Tipped everything out and found a small stone about a bean size. Jill looked at it under the microscope and its looks pyroclastic, with small feldspar crystals.
        So she probably has a nice sample from the Arenal volcano thanks to my coffee habit. The grinder is still fine.

          Does Jill like your grinder?
          Im the suspicious type.
          It seems awfully coincidental that she knows so much about the Arenal volcano and the next thing you know theres a piece of it in your grinder.

            At 5500 rpm and the full 115 horses released I reckon I could do the entire coffee snobs stock pile in less than 2 minutes!!! I should know better than to use marine/automotive examples on this site!! (even in the presence of several petrol heads)

            Cheers

              Maybe the risk of stones and nuts and other foreign objects in coffee beans can create a demand for the next coffeesnob "must have" accessory. A flat, shallow coffee bean tray, just to visually inspect the beans. The tray will have one end taper shaped into a chute so that the beans can be easily tipped into the hopper without losing a bean. The deluxe tray will have a magnetic base for trapping metallic objects, but this will be more expensive compared to the basic model. The tray will be white in colour, so it makes it easy to spot the foreign object and non stick.

              How does this sound?
