USE/CARE OF HANDTOOLS & MEASURING TOOLS - OD1621 - LESSON 2/TASK 2
4 Hold the chisel lightly against the wheel and move it from
side to side evenly across the surface.
5 Frequently dip the chisel in water to prevent loss of
temper and softening of the steel. When placing the chisel back on the tool
rest of the wheel, use your forefinger as a stop. The grinding angle may be
25 to 35.
6 After grinding, whet the chisel as discussed above.
(c) Repairing Damaged Handle Heads. If the head of a woodworker's
chisel becomes mushroomed (figure 91), it can be repaired as described in 1
through 4 below.
MUSHROOMED CHISEL HANDLE.
1 Cut the head of the handle off square (figure 92 on the
following page) with a saw.
2 Using a lathe, turn down about 3/8 inch of
length, leaving a tip about 7/16 inch in diameter, as shown.
3 Cut leather or fiber washers to fit snugly over the tip and
glue them in place. Use enough washers so their total thickness exceeds 3/8
inch. Their diameter should be greater than the diameter of the handle.
