Bead and flush on both sides . .16 For every additional quarter of an inch in thickness, add .005 to the rate per foot super.
If the panels are raised on one side, add .002 ; and if on both sides .004 ; and if an astragal or ovolo on the rising on one side, add .003 ; and if on both sides .006-to the rate per foot super.
If the price of a foot of a square door, and the number of pannels, are given, and the price of a foot of a door square on one side, with the same number of panels, and with extra work on the other side ; then, the price of a door with the same number of panels, and the same extra work on both sides, will be found by subtracting the rate of the first from that of the second ; and adding the difference to the second, will give the rate per foot extra on both sides.
Thus the rate per foot super for 11-ineh two panel door, square on both sides, is .06 ; and the rate for 11 inch two panel door, square upon one side, with quirk, ovolo, and bead upon the other, is .1, their difference which added to .1, gives .14, for the rate per foot of 11-inch two panel, with ovolo and bead on both sides of the framing.
The difference of workmanship between square-framed door-linings, backs, elbows, soffits, or wainscoting and doors that are square on both sides, supposing the panels and thick ness to be alike in both cases, can only arise from planing the panels and the framing on th'e other side of the door : therefore if the difference of the rate per foot of a door square on both sides, and one square on one side, with any extra work on the other, be added to the rate per foot of door linings, backs, elbows, soffits, or wainscoting, framed square, will give the rate per foot for dour-linings, window-liuings, or wainscoting with the same extra work.
In these rates the styles or rails are supposed without reba ting. Framed linings for walls or apertures, may be made of stuff+ of an inch thinner than doors. In common eases, the thickness of linings may be about an inch, as they are ren dered sufficiently stiff by being fixed to the wall ; this, how ever, must depend upon the distance that the panel recedes from the face of the framing, or upon the depth which the mouldings are run in the thickness of the said framing.
