Second Requirement

A kerf is a cut made by a bandsaw blade.

The raker setting is the setting of the teeth for most bandsaw

machines.

Raker tooth blades have one tooth bent to the right, the next

tooth bent to the left, and the third tooth set straight.

The pitch of bandsaw blade teeth is the number of teeth per linear

inch of the blade.

Annealing is the process or reheating metal and allowing it to cool

slowly, thereby returning it to an approximation of its original temper.

bastard-cut files are double-cut files of medium pitch, usually used

for filing steel and other hard metals.

Third Requirement

(a) Carbon Blades.

If a carbon blade is being annealed on the model

2612-1M bandsaw machine welder, press and jog the anneal switch pushbutton

until the weld is a dull cherry to cherry red in color.

Then allow the

blade to cool slowly by decreasing the jogging frequency.

(b) Dart Blades.

To anneal a Dart blade, heat the blade slowly until

the weld becomes a deep blue color. Continue to heat by jogging the anneal

switch pushbutton until the width of the blue color is one-half the length

of the band exposed between the jaws. Do not overheat or the temper of the

band adjacent to the weld will be damaged. Cool quickly by releasing the

button.
