To lap parts parallel, ensure that the lapping plate is flat. Ensure the machines hand pressure weight is also lapped flat on the plate. Avoid using felt pads or non-skid-faced weights. For best results, lap an uneven number of parts, such as three, five, or seven, and use dummy parts to make up the number.
