    Changing Rocky Burrs?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I got some new Rocky burrs from Coffee Parts today. I decided to go ahead and replace them as I have had too much channeling and inconsistent grinds since the screw incident (pucks break up and arent solid as they previously were).

    Ive run into a problem trying to change them, I cant remove the old burrs. They seem to be screwed on too tightly. Is there a trick to this or should I just use more force?

    Thanks.

    Both top and bottom?
    Whenever I clean mine, the top one just unscrews.
    Perhaps the screw incident has harmed the thread.

    In the article on cleaning your Rocky on coffeegeek,

    http://www.coffeegeek.com/guides/cleanrocky

    he mentions that you need special tools to remove the bottom burr.

    Perhaps more research is in order.

    Fatboy, not the brass burr holder, that comes off, the actual burrs are screwed on with three flathead type screws, its these screws that are really tight.

    Hi Bloop,

    If you have an electric drill with a hammer function and variable speed, you may be able to attach a suitable (meaning tight fit) sized flat bladed bit to it and try to use the hammer action to break the screw free and allow it to unscrew. I havent actually tried this myself but it should work. I guess the only touchy side to doing it this way, if you dont have a suitable soft-jawed vice to secure the burr carrier, whore you gonna get to hold it for you :-?. Anyway, it might be worth a go.

    If this fails to work, maybe you need to apply some heat, in the form of a small hot flame from a small butane torch, around the periphery of each screw just prior to hitting it with the hammer drill. If none of this works, then Id just go to bed and ask one of the Pros tomorrow morning and see what they might do in your position. All the best mate,

    Mal.

    Id be more than a little hesitant to use a hammer drill. Visions of stripped screws within seconds...

    Going down the same route though, try and get your hands on a "manual" hammer-driver (or impact driver I think theyre called). Its a screwdriver that you hit the back of it with a hammer, creating the forward push and twist.

    Heres one... http://buy1.snapon.com/catalog/item....re&dir=catalog

    Of course, you dont need a Snapon one, you should be able to find them at most automotive stores like Repco, Auto Pro, Supercheap etc.

    Well,

    Ordinarily I would be too, but most domestic drills with a hammer function these days have a variable torque control too.... ours does anyway and so did a few of the others we looked at before buying one :-?. Its a valid point though and care must certainly be exercised.... would be terrible if one or more fasteners got broken or stripped. Proceed with caution is always a good maxim,

    Thanks for the tips fellas. Considering I have already partially stripped one of the screws, I think Ill just live with it for now... if it drives me crazy Ill give it another go
