• Slabs can be rolled in either direction and clay can be added or subtracted at any time.
• Roll slabs up to 16" wide.
• The length of the slab is limited only by the space and canvas available.

The PortaRoller was designed for ceramic arts teachers who are moving from classroom to classroom and for studio potters who
need a fully functional slab roller but have limited space.

Like the other North Star slab rollers, the PortaRoller has two rolls, much like the wringer of an old-fashioned washing 
machine.  Both rolls have a small diamond pattern ("knurling") machined directly into the metal to grip the canvas.  The 
bottom roll is turned by the handle, but cannot move vertically.  As it turns, it drives the top roll through a train of 
gears.  The upper roll both turns and can be adjusted up and down.  The two rolls turning together pull slabs through easily,
and the vertical adjustment of the top roll gives an easy-to-set and infinitely adjustable thickness from paper-thin to over
2 inches.  A reference scale allows setting and repeating openings to within 1/100 of an inch.

The design gives great flexibility in making slabs.  Very thin, translucent porcelain slabs and thick, heavily textured 
architectural slabs are equally easy.  A wide variety of other texturing materials and objects can be passed through the 
machine along with the clay. Slabs can be rolled either direction or reversed on all North Star machines.

CONSTRUCTION

The PortaRoller body and rolls are made of cast and carefully machined high-strength special alloy aluminum.  Gears are made 
of the strongest material available for this application, nylon or steel.  Bushings are nylon and the remaining parts (except
plastic gear covers and knobs) are machined steel.  The Table Toppers are made of moisture-resistant Medex with a melamine 
surface.  Metal surfaces are zinc plated or coated with a durable powder coat finish.   Virtually no maintenance is required,
and the simplicity of the design ensures that any repair ever needed will be quick and easy.
