Completing an Estimating Sheet-­‐‑
Net Size-­‐‑refers to the actual or finished size.
Standard thickness of ¾”for solid and plywood with only a few exceptions.
Drawer fronts, backs and sides are ½” thick. Drawer facing is 7/16” thick.
Material-­‐‑
Solid lumber is oak or low-­‐‑grade lumber.
Plywood is oak except for the drawer sides…they are ½” Baltic Birch.
Stock Size-­‐‑refers to the rough size.
Procedure for calculating Stock Size. See page 30.
Solid Lumber:
Thickness and Width… round up to the next inch...
I.e. ¾=1, 2 ¼=3…
Length… round up to the next inch and then add 1”...
I.e. 21 ¼=23, 24=25…
Plywood:
Thickness… no change. ¾ stays ¾.
Width and Length…round up to the next multiple of 6. …
Footage-­‐‑
Calculating Footage-­‐‑use BD. FT. (BFM) and SQ. FT. formulas.
Loss Factor-­‐‑compensates for knots, waste, etc.
Solid Lumber:
Multiply the Footage by 0.3.
Plywood:
Zero… do nothing...
Total Footage-­‐‑Footage plus Loss Factor
