Always use the longest screwdriver handy for the work. More
power can be put on with a long screwdriver than with a short one, normally
because the longer screwdriver has a larger diameter handle. Hold the handle
securely in the palm of the right hand using the thumb and forefinger grasping
the handle near the ferrule. Using the left hand (if you are right-handed) brace
the tip and keep it pressing into the slot while renewing the grip on the
handle for a new turn.
When no hole is bored for the threaded part of the screw,
the wood is often split or the screw is twisted off. If a screw turns too hard,
back it out and enlarge the hole. A little soap on the threads of the screw
also makes it more comfortable to drive.
There is a regular procedure that is best used to secure two
pieces of wood together with screws: (1) find the positions the screw holes.
(2) Bore the first hole in the first piece wood slightly bigger than the
diameter of the body under the screw head. (3) Bore the second hole slightly
smaller than the threaded part of the screw. Bore as deep as half the length of
the threaded part. (4) Countersink the first holes to match the diameter of the
heads of the screws. (5) Drive the screws tightly in place using the
screwdriver.
