support casting (Fig. 21) on both the right
(inboard) side and the left (outboard) side of the
machine. Compare these measurements; they
should be within 1/16". If not, disengage the
miter gear on the right (inboard) side of the cross
bar. Adjust the conveyor bed height using the
height adjustment handle to get the same measure-
ment on both sides. Then re-engage the miter gear
on the cross bar.
If the conveyor table is still difficult to raise or
lower, the table support castings may need to be
recentered on the column tubes. To do this, loosen
the bolts in each table support casting, adjust and
tighten the set screws to hold the casting in
position. Then tighten the hex head bolts and
loosen the set screws.

After any adjustments of the castings on the
columns, check to make sure the sanding drums
are in alignment. To begin realignment of the
sanding drums, first remove the abrasive strip
from the drum. Release the V-belt tension from
the motor by loosening the pinch bolt of the
motor support casting.
Loosen two screws in lower belt guard. Slide the
motor mount up the column tube and retighten
the pinch bolt. After the feed table has been lev-
eled, loosen all four tension roller suspension bolts

(see Fig. 26). Raise the tension roller suspension
assembly to its highest position so that the
tension rollers are positioned higher than the
bottom of sanding drum(s). Then retighten the
four tension roller suspension bolts to hold the
tension rollers in that position during drum
alignment.
Primary Drum Alignment.
Using a flat piece of
wood or a steel rule as a thickness gauge, insert it
between table and primary (front) drum and
adjust the table height to gauge the thickness.
Raise the table just so the drum can be barely
turned by hand. Measure at both sides of the
drum to check that the primary drum is parallel to
the table. To adjust the primary drum alignment,
loosen both set screws at the front of the right
(inboard) drum support casting (Fig. 22) and raise
or lower the casting on the column tube to correct
drum alignment. Retighten the set screws and
recheck the alignment.
Note:
Do not loosen the
set screws of the left (outboard) drum casting as
this will cause miter gear misalignment.
Achieving a very precise primary drum align-
ment can be accomplished by disengaging the
right (inboard) miter gear (Fig. 23) from the
height adjustment cross bar, and using the height
adjustment handle to finely raise or lower the
inboard side of the table to achieve parallel align-
