Troubleshooting
Incomplete Micro-Bevel
This is most likely caused by a combination of two factors:
a) the edge of the thick platter has been mushroomed
either from being dropped edge first on a hard floor
or the PSA backing on the abrasive disc is peeling
on the edge; and
b) while grinding the primary bevel, the blade was
traversed partly over the outer edge of the abrasive
disc. (See
Chapter 4, How to Sharpen a New Tool,
Step 2: Create the Primary Bevel
.) To fix the problem,
it is necessary to start again with 100µ abrasive.
Motor Troubleshooting
Drive Train
If the V-belt jumps off the motor pulley, it is probably
due to the misalignment of the motor pulley and
turntable pulley. Check that the pulleys are aligned.
Place a straight edge across the top surfaces of the two
pulleys (see
Figure 4
). If they are not aligned, loosen
the set screw in the motor pulley and align them.
V-Belt Tension Adjustment
Loosen the three motor mount screws. Pull the motor
pulley as shown in
Figure 3
to tension the belt. Tighten
the motor mount screws. The V-belt doesn’t need to be
any tighter than you can comfortably set by hand.
