THE LARGE CYLINDRICAL POST-MOUNTED VEE BLOCK (OUR PART NUMBER VB-2000-CPM) IS A VERY HEAVY LOAD-CARRYING DEVICE.

IT IS BUILT AROUND A TWO-INCH DIAMETER CYLINDRICAL ENVELOPE.

THE CYLINDRICAL MOUNTING POST IS PRECISION GROUND, TO THREE QUARTERS OF AN INCH (3/4" 0.750", 19.05 MM) IN DIAMETER, PLUS OR MINUS .003" (.0762 MM) AND IS THREE QUARTERS OF AN INCH (3/4", 0.75", 19.05 MM) LONG.

THE ADJACENT FLAT FLANGE IS PRECISION GROUND FLAT AND SQUARE TO THE POST.

THIS DEVICE IS DESIGNED FOR UNIVERSAL MOUNTING FROM EITHER THE FRONT OR FROM BEHIND.

THE CENTER OF THE POST IS DRILLED THROUGH AND THREADED TO ACCEPT A FASTENER THAT IS THREE EIGHTHS OF AN INCH (3/8", 0.375", 9.5 MM) DIAMETER BY SIXTEEN THREADS PER INCH. THIS CAN BE USED TO HOLD IT DOWN FROM THE REAR.

THE DRILLED CENTER HOLE OF THE VEE BLOCK IS COUNTERBORED IN THE FRONT TO ACCEPT A FIVE-SIXTEENTHS ( 5/16" ) OF AN INCH (7.9 MM) DIAMETER SOCKET HEAD CAP SCREW.

THIS ARRANGEMENT CAN BE USED TO CLAMP IT DOWN FROM THE FRONT.

THIS DEVICE IS COMPATIBLE WITH LOAD SPHERES FROM ONE AND ONE QUARTER ( 1 1/4" ) OF AN INCH (32 MM) TO TWO-INCH (51 MM) DIAMETER.

THE INCLUDED ANGLE OF THIS VEE BLOCK IS 90 DEGREES. THE FLAT PRISMATIC SURFACES OF THIS VEE BLOCK ARE PRECISION GROUND WITH THE FACE OF THE GRINDING WHEEL NOT THE PERIPHERY. THIS TECHNIQUE BREAKS UP THE LAY OF THE SURFACE TEXTURE AND GIVES THESE VEE BLOCKS FAR SUPERIOR REPEATABILITY.

THESE VEE BLOCKS ARE MANUFACTURED FROM A VERY HIGH CHROME, HIGH CARBON, MARTENSITIC STAINLESS STEEL. THIS ULTRA FINE-GRAINED MATERIAL IS HARDENED TO 58 HRC MINIMUM.

THESE VEE BLOCKS ARE HIGHLY MAGNETIC.
