The belt sander is a valuable ally of the handyman even when he is a beginner. Powerful but easy to tame, it is ideal for flat surfaces.
The basics for working with a belt sander
Equipped with a continuously rotating belt, this machine whose power varies from 600 to 1100 W must be controlled not to dig the material.
The sander must be moved smoothly and evenly.
The steel sole that defines the contact surface when sanding must be wide enough to provide good performance.
The current sanders are equipped with an electronic dimmer which allows the speed to be adjusted according to the desired sanding and the nature of the material. Slow speeds are used primarily for working on heat sensitive surfaces.
The abrasive slips on a sole between the two rollers. To facilitate the circulation of the band, it is sometimes lined with a graphite canvas.
The electronic variator makes it possible to adapt the speed to the type of materials.
Slow speed for heat-sensitive coatings, fast for hardwoods.
The tape has a direction of scroll markable by an arrow.
To avoid tearing, match it with the one indicating the direction of travel on the machine.
To remove a used band, rotate the side lever to compress the spring and give slack to the fabric.
Pulling it on each side makes it easy to clear.
To align the belt, turn on the sander.
Using the wheel, change the angle of the rotation axis of the front roller for parallel scrolling.
Even if the sander has a built-in suction and a bag, connect it to a vacuum cleaner to better evacuate the dust and preserve the bands.
Start the engine at full speed before approaching the surface to be sanded.
At first contact, hold back a little the machine that tends to go forward.
Do not press on during work; the belt sander could dig the wood.
Just guide her in the direction of the fibers and let her weight do the rest.
On some models, a support plate is anchored on one side and screwed on the other.
If the non-slip pads are not enough, lock the plate with clamps.
To plan rough woods with a short sole, treat the wood guide against the parallel guide and the sanding surface, machine turned upside down.
If the sander is attached to a workbench, a stationary machine is available.
Associated with a lateral guide and angle, it becomes a practical vertical tool.
A metal sole can sometimes be added: very practical for sanding parquet, it makes it possible to limit abrasion and avoids digging the wood.
This sanding frame is attached to the soleplate by pins. You must unscrew the depth adjustment knob to engage the pins.
Once the frame is in place, the machine is raised or lowered by turning the adjustment knob to change the depth of the sanding.
