PART 3: Drum-to-Conveyor Height
For this adjustment, you will find a reference
height for the front drum and then adjust the
rear drum so it is 0.007" to 0.010" lower than the
front drum. See
Figure 27
.
To adjust the drum-to-conveyor height, do these
steps:
1.
Lower the conveyor table, and position the
30" gauge block to one side of the conveyor
belt and flush with the end of the feed
conveyor drive roller. See Figure 28 .
2. Raise the conveyor table so the gauge block
barely touches the front drum and mark this
height position with tape on the handwheel
at the 12:00 o’clock position. See
Figure
29 .
3. Turn the handwheel counter-clockwise exactly

4. Unlock the rear-drum micro-adjusting lock
lever and turn the micro-adjusting knob so
the rear drum lowers until it just barely
touches the gauge block.

at both ends of the rear drum.

NOTICE
Make sure you use the same part of the 30"
gauge block at the opposite side of the conveyer
belt when adjusting the drum-to-conveyor
height. Otherwise, the adjustment may be
inconsistent.
NOTICE
Once the rear drum height is set, the height
can be fine-tuned later without having to
complete all four parts of this section. However,
you must make sure that when you adjust the
rear drum height you adjust it equally on both
sides so it stays square and level with the
conveyor table. Using a pencil, mark a squiggly
line on the workpiece and sand it to test for
even sanding. Look for uniform removal of the
line. If the line is not removed uniformly,
readjust the sander accordingly.
