68Z0220 - Drum-Sander Bearing Support
Mounting a drum sander on a drill press is a convenient way to sand, but there are two shortfalls. First, the bearings on a drill press are designed for axial loading – side loading causes quill wear and run-out. Second, extra-long drums tend to deflect as you apply pressure when sanding, producing a sloping edge on the workpiece.
Our drum-sander support system solves both problems. The bearing support (with a live center) engages the matching center in the bottom of our specially drilled shafts. All you do is lock your quill so there is sufficient pressure on the bearing support to prevent it from sliding on the drill-press table. For drill presses that don't have locking quills, just raise your table to provide the same engagement.
To use the bearing support, a modified shaft is available separately to retrofit 1 1/2" or 2" long sanding drums.
A screw-in fitting is also available separately to adapt our large 3" × 3" sanding drum.
Made in Canada.
Drill press bearings are designed for axial (up-and-down) loads, not lateral (side) loading. Using a drum sander creates sideways forces that cause quill wear and introduce runout over time, reducing the drill press's accuracy for drilling.
The bearing support, which includes a live center, is placed on the drill press table. The specially drilled shaft of the drum sander engages the live center at its bottom. The quill is then locked, or the table raised, to apply enough downward pressure to keep the support in place. This transfers lateral forces away from the quill bearings.
With the modified shaft (available separately), the bearing support works with 1 1/2" and 2" long sanding drums. A screw-in fitting (also available separately) adapts the system for the large 3" × 3" drum. The drums themselves are not included with the bearing support.
No. For drill presses without a quill lock, raising the table to provide the same downward engagement against the bearing support works equally well.
If your existing drums are standard 1 1/2" or 2" drums, you will also need the modified shaft (available separately) to retrofit them. For the 3" × 3" drum, the screw-in adapter (available separately) is required.
