Sanding Drum &
Conveyor Parallelism
The sanding drum and conveyor must be parallel to one another to obtain accurate sanding results. This setting is made at the factory and should not have to be made again. However, if it is necessary to adjust the sanding drum and conveyor parallel to each other, follow the procedure below.
This process involves multiple accurate measure- ments, patience, and
Using a dial indicator is probably the most accu- rate method of taking measurements for this pro- cedure. However, you can use gauge blocks and feeler gauges to attain acceptable results.
To make gauge blocks, square up a 7' long 2x4 (refer to your jointer manual for detailed instruc- tions), then cut it in half.
To check the sanding drum and conveyor par- allelism:
1.DISCONNECT THE SANDER FROM POWER!
2.Remove the sanding belt from the sander.
3.Record the precise measurements between the lowest point of the sanding drum and the conveyor from
To adjust the sanding drum and conveyor par- allelism:
Note: Use the measurements you recorded when checking the parallelism in the previous procedure.
1.Loosen the four mounting cap screws on the right side of the column base shown in Figure 35.

2.Tighten or loosen the upper or lower jack screw to bring the sanding drum and con- veyor parallel to one another to within 0.005" from side-to-side.
—To raise the left side of the sanding drum up, tighten the upper jack screw.
—To lower the left side of the sanding drum, tighten the lower jack screw.
3.Evenly re-tighten the four mounting cap screws.
4.Plane a 15" wide piece of stock, then send it through the sander until it is flat.
5.Use a caliper to measure this workpiece from side-to-side. If these measurements differ more than 0.005", repeat Steps 1–4 until you are satisfied.
