William,
I do my initial polish with a wheel. Even though it is a special jeweler's
wheel with special bearings and other things to reduce vibration to almost
nothing, I still must do the final buffing by hand with two buffs. I cannot
explain in words how to polish a dag plate. One must be shown by an
experienced daguerreotypist. A poorly polished plate not only gives a poor
image but is not as sensitive as a properly polished one. I have read
somewhere that the early daguerreotypists had machine powered leather buffs.
Perhaps something could be devised but I do not know how well they would
work. During my training I was taught how and where to place my hands during
buffing and how to get an even polish. Also how to know when the plate is
correctly polished. It struck me as being similar to mirror grinding for
astronomical telescope mirror when the final stage is also done by hand.
