I own an ancient Delta-Milwaukee "Toolmaker" surface grinder ...

months of idleness, the surface finish after taking only a light 0.002-inch
pass is terrible. I have no operating manual or parts book; can't even find
the serial number.. The brass nameplate says "Only use balanced wheels".
Any suggestions as to a remedy, and who can balance a grinding wheel?
Thanks, Dave Anderson

I don't believe they are capable of the smoothness of a normal surface
grinder due to flex in the bolt-on round column that supports the
swivel head. Mine only gives a smooth ripple-free finish if I feed it
one division (0.0005") or less and turn the Y feed slowly so left and
right passes are slightly diagonal to break up the self-reinforcing
washboard-road effect.
