Belt/Disc Sanders

What safety tips does one need to keep in mind before using a belt & disc sander?

• Use eye protection to prevent injuries from woodstock kickback or sawdust that flies off the surface.
• Most machines produce high levels of noise and a continuous hum can be uncomfortable and damaging to ears. It is better to use hearing protection while operating a disc or belt sander.
• Use caution while handling workpieces secured to tools. Keep your fingers away from the sandpaper which might rip off your skin within an instant.
• Avoid wearing loose fitting clothes as they can get caught in spinning drums while working.
• If possible, start sanding with grain as it helps prevent wood from slipping off the belt while in motion. Always sand in a downward position and avoid upward movement for better control.
• Proper operation and maintenance of dust collection equipment is essential for effective dust minimisation.
• Workpieces must be large enough to be held while keeping body parts away from moving abrasives.

How to clean up a disc / belt sander?

• Disassemble any fixtures, clamps, etc used in the sanding operation. Return all parts to their proper locations.
• Disconnect the dust collection hose and return the sander to its original location.
• Clean up the area. You can use a shop vacuum to clean up any additional sawdust.

What is the difference between a disc and belt sander?

Belt sanders are much bigger in size than bobbin & disc sanders. Its long, flat surface makes it ideal for flattening and levelling long pieces of timber, such as panelled doors.

How to maintain belt / disc sanders?

First, make sure that the belt is oriented properly. Some belts have a preferred direction, indicated by an arrow on the inside. Non-directional belts can be installed either way. The operator will have to adjust the tracking to keep the belt centred on the roller. Hold the sander up, turn it on, and see if the belt either rubs against the housing or starts working its way off the rollers. With the trigger on, adjust the tracking knob until the belt is centred on the rollers. You might have to make a slight adjustment when the sander is on the wood. Some sanders have variable speeds. You can go at the maximum speed most of the time, but you'll want to throttle it back for delicate work.
