conveyor belt to
Drum Alignment
to ensure good sanding results, the conveyor belt
and sanding drum must be parallel with each other
from side to side (see the illustration in
figure 34).
otherwise, more material will be removed from
one side of the workpiece than the other.

the goal of this procedure is to bring the conveyor
belt and sanding drum parallelism within 0.05" dif-
ference from side to side.

to check and adjust the conveyor belt to sand-
ing drum parallelism:
1. Make sure the gibs are properly adjusted.
2. plane the board so that the thickness on each
side of it is equal.
3. take several light cuts through the sander
without rotating or flipping the board.
4. Make measurements at "a" and "B" as indi-
cated in
figure 34.
— if measurement "a" is less than "B", loosen
or remove the cap screws on the
right
con-
veyor support (see
figure 35) and shim
between the support and frame to com-
pensate for the difference between "a" and
"B".

— if measurement "B" is less than "a", loosen
or remove the cap screws on the

conveyor support and shim between the
support and frame to compensate for the
difference.
5. repeat Steps 2–4 to verify the adjustment.
if necessary, repeat this procedure until the
conveyor belt and sanding drum parallelism
is within 0.05" difference from side to side.
