24. SANDER, BELT (3x21” Craftsman 315.117131, Porter-Cable 352VS)

The Belt Sander is useful for sanding the surface and edges of pieces of wood that

are too large to be sanded on the disc sander. The Belt Sander can be used on flat

or curved pieces.

24.1. Safety Precautions

a. ALWAYS UNPLUG before changing abrasive belts.

b. SANDING OF LEAD-BASED PAINT IS NOT ALLOWED.

c. ADJUST TRACKING of the abrasive belt prior to sanding operation.

d. PRIMARY SAFETY HAZARD: Workers may catch their hands,

clothing, or jewelry in the in-running rolls. Also, contact with an

abrasive surface can cause abrasions and lacerations.

e. ALWAYS sand on the downward-moving side of the disk or belt.

f. WOOD splinters and chips may be thrown from the sanding action.

g. REPLACE torn, frayed, or excessively worn belts. A worn-out belt can cause massive heat

buildup, which can cause it to tear or break and pelt the surrounding area with projected bits.

24.2. Setup & Use – Belt Sander

a. Make sure the dust collection bag is securely attached before sanding, AND make sure the dust

collection valve is open to allow dust particles to be blown into the dust collection bag. After

long periods of sanding, or when first using the tool, check to see if the dust collection bag

needs to be emptied.

b. Start the sander above the material, then lower the sander so the back end makes contact first.

Move the sander back and forth in a straight line for best results.

c. Work through the “grits". This is the process of sanding a workpiece by using progressively finer

pieces of sandpaper to get a smooth finish. Each progressive piece of sandpaper removes the

scratches from the previous sanding. Skipping grits to save time is not necessarily a good idea.

You will often end up sanding longer just to remove the scratches left by the previous grit. This

is more important with harder woods like maple than it is with softer woods like pine.

d. For better-looking results, always sand with the grain of the wood, especially with coarse

sandpaper.
