dressing the Wheel

New wheels frequently are not true

and during operation often become

grooved, glazed, out of round, or

misshapen. At these times, they will

need dressing. You will need a grind-

ing wheel dresser for this operation.

Dressers are available from Harbor

Freight Tools.
Standing to the side of the wheel, let

the Bench Grinder run for a full min-

ute with no load. If the GRINDING

WHEEL runs straight and true, you

will not need to dress it prior to op-

erating. If it is not, proceed with the

following steps.

With the Bench Grinder running, grip

the handle of the dresser firmly with

one hand and the arm of the dresser

with the other.
Using the TOOL REST (7) as sup-

port, apply the dresser evenly to all

surfaces of the GRINDING WHEEL.
Continue step 3 until the GRINDING

WHEEL is straight and true.
