Plexiglass and diamond paste flattening
Sanford Levy
>Has anyone tried laying a piece of plexiglass, or other plastic, down on a flat piece of plate glass for flattening the backs of planes etc with diamond paste? The glass is flat, and the plexiglass on top will therefore be. But the plexiglass is sort of soft so that the diamond bits can (I assume) stick into it the way (as I understand it) you want for flattening yor plane. (If I understand right, the inability of the particles to stick in regular glass is one of the problems with diamond past on regular glass. The reason some people use a maple block is so that the particles will stick nicely.) You could use a separate sheet of plexiglass for each grit so there is no problem of contamination. If the plexiglass wears out it can be discarded. It is not very expensive anyway. I have not tried this, and it may be one more of my dumber ideas! Sanford
