For the Model G0459 Drum Sander to function properly, the sanding drum must be aligned in two directions: (1) parallel to the conveyor belt and (2) perpendicular to feed direction.
The drums can be adjusted in fine increments at the pillow block bearings and in larger increments by using the table lift screws (Page 33).
While adjusting the drum, keep in mind that hav- ing the drum parallel to the conveyor belt is critical to the sanding operation. Care should be taken to make the tolerances as close as possible (within 0.002" from one side to the other) when adjusting the drum height.
The tolerances for having the drum perpendicular to the feed direction are much more forgiving, even allowing up to 1⁄8" difference from one side to the other before causing problems.

5.Raise the table until the gauge blocks just touch the bottom of the sanding drum.
Note: A good way to know when they are touching is to rock the sanding drum back and forth while raising the table until you hear or feel contact with the gauge blocks.
