  We describe a new type of torsional oscillator, suitable for studies of
quantum fluids at frequencies of $\sim$ $100$ Hz, but capable of reaching high
velocities of up to several cm\,s$^{-1}$. This requires the oscillator
amplitude to exceed $100$ $\mu m$, which is much too large for a conventional
capacitor-driven device. We describe the new geometry for the oscillator,
discuss its design, and report our initial tests of its performance.
