When using a measuring tape, the metal tab at the end can become
loose. If you push and pull on it, it can move by up to 1/8" of
an inch. When making precise measurements, keep the tab in the
same position when transherring the measurement to avoid gaining
or loosing distance.
Always use the same tool when measuring. Otherwise, small variations
between tools may result in inaccuracies in your results.
Don't start measuring from the end of a
tool, instead start from the 1 inch or other mark. The end
of the tool sometimes is not properly marked or can become worn
down, making it inaccurate.
Place masking tape over the cut line to prevent tear-out
from damaging the wood's surface.
Stacking scrap wood on top and bottom of a piece being cut will
prevent tear-out.
When cutting an inside corner into a board, leave the last bit
to be cut by hand with a dove tail saw or a chisel.
