DIAMOND ROD MESHS   30/40 40/50 50/60 ... 600

LARGE SPHERE MACHINE
New design requires no springs or clamps. Gravity holds ball in place and assists in obtaining best roll control.

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.  $2000.00 Plus Shipping
