    The problem with using a vibratory tumbler for steel shot is not the
    power of the tumbler as much as it is the contour of the bowl, the
    small gemstone works well with it's angled bowl, but it is my
    understanding that they no longer make this modle, We purchased a
    larger gemstone tumbler and it worked very well for several years,the
    motor burnt out so we bought two 3 Quart ultravibe tumblers and were
    very heart broken when we tried to use Stainless Steel Shot, it
    wouldn't work the shot just vibrqated in place, OK so I put the
    orange bowl from the gemstone tumbler and got more than sufficent
    cavitation to produce great results, So Lesson to be learned is if
    you look at the Raytech tumblers they have bowls specifically
    designed for tumbling with steel shot if you look at those bowls the
    sides are not as convex as are the other tumblers designed for
    abrasive finishing, Possibly see if the gemstone still make a 3 quart
    bowl it will easily accomodate 20 to 25 pounds of shot and has an
    excelent cavitation, also y9ou can set up your own flow through
    system using truck tire inflAtor valves the kind the are threaded on
    the outside and have a rubber grommet on the inside , a cheap water
    pump from a garden supply (the kind used for small fountains and two
    small water valves for controlling flow in and out Outward flow is
    very important so you dont loose too much solution, also I quit
    buying the Expensivwe stainless steel burnishing compound liquid and
    started using Simple green at 1/2 cup per 2 gallons of water for both
    abrasive tumbling and for polishing with Stainless shot, It works
    very well and is a lot less expensive. The medium size gemstone
    tumblers are great units as the bases are made of plastic and don't
    rust out loke the ultravibe bases do, But maybe I expect things to
    last too long any way. Raytech is excelent but you will pay what
    seems to me to be a very high price for minor differences, I really
    shouldn't whine about the ultravibes the one left is still over 10
    years old and still works and hasd had very limited care. Kenneth
