The first visilapping machines in America came from Shor Those machines were quickly copied until very few remembered the origins.  Now Shor introduces a new kind of visilap hood- The WhirlWind. When polishing with a visilap, it is important to apply the jewelry to the wheel in the right place on the visilap wheel in order to direct the dust toward the intake hole in the hood.  Inexperienced visilap polishers (and experienced thieves) may direct the dust past the hole, causing the gold dust to accumulate inside the hood.  The intake hole on the WhirlWind Visilap hood extends along the entire left hand side of the hood, making impossible to steal gold dust by redirecting the stream.
