    Irregular threading?

    I'm building an activated carbon filter for filtering cheap vodka for use in making liqueurs. I'd like to be able to screw the end of a tube (preferably copper) on to the end of the bottle directly, but they seem to use a rather wonky sort of threading. Can anyone make any suggestions as to a way I might go about this?

    Joseph,
    Why? Just make the opening in filter big enough so that you can pour it streight into it. If you fit the filter directly onto the bottle the liquid will not come out unless air can get into the bottle. Think about a water bottle upside down in a hamsters cage.

    1) use some epoxy putty and 'cast' a socket for the bottle threads. Use plenty of wax or something to make sure the epoxy doesn't stick to the threads. You could then turn the epoxy to make it look nicer and thead the other end for a copper fitting.

    2) Use a rubber cork.

    3) Use some sort of rubber bung you could drill just slightly undersize to the bottle.

    I didn't see anywhere in his thread where he said he was making "cheap hooch"! He is not wanting to spill a drop, so it is either so potent it will cause a fire or eat a hole in the floor, or it is more expensive than gold!

    Actually, he said he was "using cheap vodka." Could you just pour it through a Brita filter?

    Guys, this is Joseph we are talking about here...

    I've got a feeling he has a little higher design in mind!

    I made some Drambuie from vodka once. It gave everyone at the party hives.

    I helped make a Hairy Buffalo once. Ate one or two slices of the apples floating on top before I passed out.
