Thread: lapping problems

Lap your Norton on some 220 wet/dry sand paper. Rotate the Norton lap around several times through the process. When lapping you hones also rotate the hone around from time to time and also the lap. If your Norton lap is flat within reason your results on the hones should be just as good. Rotating them while lapping will improve the results. Flat is a relative term. DMT's may give better flatness if rinsed while lapping. With the Norton, I don't rinse very often and allow the slurry built up on the lap to assist in the lapping process. Rinse when the groves in the lap are close to full with slurry. That works best for me.
