Re: ATM - Polishing & Pitch Lap Questions

                        Hi John,

 

                It looks like you have the "hang" of polishing techniques &

            you're on the way to make a good one.

 

                It looks like your lap is in good shape [the partial pitch

            squares are no problem as long as they don't crumble off &

            cause "sleeks"] SO, my 2 cents worth, Just brush your lap

            {with a brass wire brush]  recharge & press.

 

                To create a good sphere [and polish clear to the edge] work

            part of the time TOT. If you alternate MOT with TOT at 1/3 dia.

            strokes most of the stroking errors will cancel out & you will

            arrive at a good sphere. Contrary to what looks like common

            sense, polishing TOT will not create TDE [it can actualy cure it]

 

                                    Hang in there & good luck, Yours, Bob Allen
