    Help, we don't know what size tumbler to get. We've decided on a
    vibratory tumbler which I believe would be faster than rotary for
    polishing, and poss quieter. And we like the ones with a clear lid
    and the way you can check the work easier. 

    However we do have to deal sometimes with quite big stg pieces:
    55x30mm leaf shapes (2 1/4"x1 1/4").

    Ruth saws the shapes out and files the edges, and the stg shape
    backs a titanium/niobium leaf shape which is matt-surfaced, not
    polished. 

    What would you say about the SIZE of tumbler needed? Does the size of
    workpiece dictate size of machine? 

    Polish? I suppose there are thoser who would say there are several
    degrees of polish. What sort of polish do we mean? Well, at the
    moment we use white rouge on a 6" cloth mop on a slow (1400rpm)
    motor. It's not a super-high polish. 

    As it's a big investment for us any help would be appreciated. 

Brian
