How to Use an Edge Sander: Setup, Technique & Safety

A stationary edge sander is one of the more straightforward machines in a shop once you know its two or three key settings — but those settings (horizontal vs. vertical, platen angle, table height) trip people up the first time. Here's how to set one up and run it correctly, using our own Laguna 6|89T as the example.

What This Machine Is (and Isn't)

Worth clearing up first, since the term covers two very different tools: this guide is about a stationary shop edge sander — a benchtop or floor-standing machine with a continuous abrasive belt, used to true straight edges, square up glue joints, and smooth panel and component edges in cabinetmaking and furniture work. It's not the same machine as a handheld or walk-behind edging sander used to refinish the edges of a hardwood floor near baseboards — different tool, different technique, different industry. If it's a shop edge sander for truing lumber and panels you're after, that's exactly what's covered below. For the fuller picture of what this machine is and how it compares to a belt sander, see our companion guide: What Is an Edge Sander?

Setting Up an Edge Sander

Before you turn the machine on, get three things set:

• Table height. Set the front table to a comfortable working height for the stock you're running — on the 6|89T, the table adjusts from 38" to 41".
• Platen angle. For a square edge, the platen should read 0°. For a chamfer or beveled edge, tilt the platen to the angle you need — the 6|89T's platen tilts 0° to 90°.
• Belt tracking. Before feeding any stock, briefly run the belt and confirm it's tracking centered on the platen and rollers, not drifting toward either edge. Most machines have a tracking adjustment knob near the top roller for exactly this.

Connect dust collection before you start — an edge sander throws a steady stream of fine dust, and a 4" port needs a dust collector sized to actually pull it, not a shop vacuum straining to keep up.

Horizontal vs. Vertical Operation

A swing-belt edge sander like the 6|89T can run in either orientation. Vertical is the default for most edge work — the belt runs straight up and down, and you feed the workpiece's edge into it while the piece rests flat on the front table, which is the setup for truing a straight edge or squaring a glue joint before assembly. Swinging the belt to horizontal changes the sanding plane to flat-on-the-table, useful for face-sanding small parts or working the end table (10" x 12" on the 6|89T) for shorter pieces and angled cuts that don't need the full 30" of front table support. Get comfortable switching between the two — most shops end up using both regularly rather than settling on one.

Sanding Technique

Feed the workpiece steadily into the belt rather than jamming it in and holding still — a moving workpiece sands evenly, while stopping in one spot burns the wood and can groove the belt. Keep the piece flat against the table and, for a straight edge, guide it in one continuous pass rather than sanding in short back-and-forth strokes, which tends to round over corners that should stay square. Light, even pressure does more than force — let the belt speed do the cutting. An oscillating belt (the 6|89T oscillates 1/2") helps here too, since it moves the abrasive up and down across the workpiece as you feed, which spreads wear across more of the belt and reduces loading compared to a belt that runs in a fixed track. For edge work that curves rather than runs straight, an edge sander isn't the right tool — see our guide to the spindle sander for inside curves and cutouts instead.

Grit Selection

For truing a rough or slightly out-of-square edge, start around 80 or 100 grit to remove material efficiently. Once the edge is flat and square, step up to 120 to clean up the coarser scratch pattern before glue-up or finishing — most glue joints don't need anything finer than that, since the surface will be hidden once clamped. See the grit range this kind of work typically uses in our Sandpaper Medium Grit collection, or read our full breakdown of what grit counts as medium sandpaper if you want the full picture.

Safety Checklist

• Wear eye protection and a dust mask or respirator — fine sanding dust is a real long-term exposure risk, not just a nuisance.
• Keep fingers clear of the pinch points where the belt wraps the rollers, and never reach toward the belt to clear debris while it's running.
• Know where the emergency stop is before you start — the 6|89T's control panel puts it within easy reach of the operating position.
• Don't force a workpiece into the belt to speed things up — forcing it increases kickback risk and is more likely to gouge the piece than actually save time.

FAQ

How do you use an edge sander to true a glue joint?

Set the platen to 0° for a square edge, feed the board's edge into the vertical belt in one continuous pass with the face flat against the table, and use 80–100 grit to remove material, then 120 to clean up the surface before glue-up.

What's the difference between horizontal and vertical operation on an edge sander?

Vertical is the standard setup for edge work — feeding a board's edge into an upright belt. Swinging the belt to horizontal changes the sanding plane to flat-on-the-table, useful for face sanding small parts or working the end table on shorter and angled pieces.

How do you use a sander machine like this safely?

Wear eye and respiratory protection, connect dust collection before starting, keep fingers away from the belt's pinch points, know where the emergency stop is, and feed stock steadily rather than forcing it or letting it sit still against the moving belt.

Is a shop edge sander the same as a floor edging sander?

No — a shop edge sander like the one covered here is a stationary machine for truing board edges and glue joints in cabinetmaking and furniture work. A floor edging sander is a different, handheld tool used to refinish hardwood floors near walls and baseboards.
