To saw a straight line, tilt the saw forward slightly. Then the cut
already made will help guide the blade, and it is easier to sight
the straight line along the blade.
To saw curves, keep the blade perpendicular to the metal. Tilting
the saw forward while rounding a curve will pinch the blade causing
it to break prematurely.
To make a sharp turn, continue the same up and down rhythm without
any forward pressure. Then slowly rotate the metal around the
moving blade. On each downward stroke, make a slight sideways cut
until you reach the new direction. Brad Simon CMBJ www.BWSimon.com
