You can put this solution on YOUR website!
Let c = count of runs through the planer. Thickness removed for c runs is 0.015c.\r
\n" ); document.write( "\n" ); document.write( "Thickness of board if starting 0.875 inches thick is 0.875-0.015c. Wanting the resulting thickness of the board to be 0.74, then makes the statement:\r
\n" ); document.write( "\n" ); document.write( "\"0.875-0.015c=0.74\" and you would make a sensible judgement in case c is not a whole number.
