You are constructing a chest with drawers such as the one shown in the figure below using

flatsawn sugar maple. Assume that shop conditions put your lumber at an EMC of $7\%,$ but

your experience has determined that with the light oil finish you plan to use, the EMC of the

finished piece could go as high as $14\%$ in summer weather. The height of the drawer front $($F$)$

should be no greater at $14\%$ MC than the $9$ inch vertical drawer opening $($D$/$O$).$ How much

shorter than the drawer opening should the drawer front be at the current moisture content

of $7\%?$
