LARGE SPHERE MACHINE
New design requires no springs or clamps. Gravity holds ball
in place and assists in obtaining best roll control. Will make
medium to large spheres up to 14 inches (possibly larger but I don't
care to lift them). Comes with one set of self-made diamond cups.
Rotates at 157 RPM. Requires 16 Amp, 115VAC, 60 cycle electric
service. No need to pre-grind points; this machine will do it for
you. Uses 1 inch pipe thread fittings for grinding cups.
