Description

I’ve not seen one of these before.  Patented by  one Isaac Rommer of Newark, NJ in 1910,  this uses a cam-type action to put pressure on the workpiece.  The adjustable depth is done by means of a toothed rib.   The total capacity is around 3 or 3-1/2 inches.

These look like they’d be most useful to luthiers.
