[Illustration: Wiring Forms Prevents Bulging.]
The first consideration in planning Forms is the use to which they are
to be put. Neglect of this point means waste of money and time. If they
are for work afterward to be covered with a veneer coat, the finish of
the surface is of small consideration, while the alignment of the Form
is all-important.
If a tank or retaining wall is to be built, the fact that the Forms are
not in exact alignment will hardly be noticed.
In planning Forms for large structures, the oftener each section is
used, the less the cost. You save money if they are rigid in alignment,
and well surfaced. In other words, if you count on using your Forms
over and over again, the more nearly perfect they are, the more often
they can be used, and the cheaper they become.
If Forms are to be used only once, as is generally the case on the
farm, they should not be nailed so securely as to prevent their being
readily taken apart, and the lumber used for something else. If often
pays to put them together with screws. If nails are used, do not drive
them home.
