USE/CARE OF HANDTOOLS & MEASURING TOOLS - OD1621 - LESSON 2/TASK 2
Usually the bevel angle can be determined by examining an undamaged portion
of the blade, but if the bevel has been distorted for its entire length, an
undamaged pair of shears of a similar type should be examined to find the
correct bevel.
The correct bevel angle could be determined by using the
above figures, if it is known specifically what materials will be cut by the
shears. When grinding, use a fine grain abrasive wheel, properly dressed.
Adjust the grinder rest to a position that will give the correct bevel.
Place the shear blade on the rest with the bevel side down and move the
blade into contact with the turning wheel. Move the blade from side to side
during grinding to ensure a straight cutting edge. Dip the blade in water
frequently when grinding to preserve temper; remove any wire edge on the
oilstone.
