Hi Lindsay,

    It's hard to judge from a written description exactly what is
    happening, but it seems to me that one possible cause of your flex
    shaft's vibrating MAY be overloading it, asking it to do too much. I
    also have a TX, and I do use it hard - grinding alabaster with an
    approximately 2" diameter wheel in the 1/4" handpiece and using the
    desktop speed control. When I put pressure on the grinding wheel the
    shaft jerks and stutters rythmically. Since there is elasticity in
    the shaft I believe this is to be expected and constitutes a sort of
    innate warning signal. On one occasion in fact when I kept on
    grinding anyway the shaft jerked so hard it pulled itself out of my
    hand & wrapped itself into a knot. I thought "oh-oh, so much for
    that shaft" but after untwisting it worked just as before. 

    Mike Zagielski are you monitoring? What does it mean when the shaft
    stutters and goes rhythmically jerk-jerk-jerk? 

Cheers,
