I designed this to mount a rotary to my work table and use it for burnishing, sanding etc. on small items that require precision work. Designed for a 27mm benchtop thickness, though it can be remixed to suit your needs. Requires two short bolts, one long bolt and nuts.

A reinforced design for high-RPM and torque work can be found here:
