Delta 31-460 disc sander - type 2 Parts

Pricing for a Delta 31-460 disc sander (type 2) varies widely based on condition, included accessories (disc, table, guards), and whether it’s new, used, or refurbished. For the most accurate current price, compare listings by the exact model number and verify what’s included before buying.

Because this is a power tool and many units are sold used, prices usually fall into these buckets:

• As-is / needs work: lower priced; expect missing parts or electrical issues
• Used, working: mid-range; normal wear, complete guards and table
• Clean, serviced, or with extras: higher priced; may include sanding discs, jigs, or a stand

These checks help you judge value quickly on a Delta 31-460:

• Motor behavior: starts quickly, no burning smell, no excessive sparking at brushes
• Vibration: disc runs smoothly; wobble often points to arbor, bearings, or disc issues
• Table and trunnion: table tilts and locks firmly; no cracked castings
• Switch and cord: no intermittent power; cord jacket intact
• Dust collection and guards: present and not broken (safety and cleanup)

With sanders, the purchase price is only part of the cost. A “cheap” unit that needs bearings, a switch, or wiring repair can quickly cost more than a solid used machine.

When you shop, match the tag to 31-460 exactly (Delta made similar sanding centers and disc sanders). For parts lookup and model-based searching, start with the model page parts list, then use Sears PartsDirect to search by model number and compare options.

For a Delta 31-460 disc sander (type 2), belt size is determined by measuring the belt’s width and overall loop length. The most reliable method is to measure the old belt (or the roller path) and record the size as width x length (for example, 4 in. x 24 in.).

• Measure belt width: Measure straight across the belt’s back (the non-grit side).
• Measure belt length using the old belt (most accurate):
  • Cut the old belt straight across.
  • Lay it flat and measure end-to-end.
  • If you cut it at a point other than the factory seam, double the flat measurement.
• Measure belt length using a string (if the belt is missing):
  • Wrap a non-stretch string around the rollers where the belt rides.
  • Mark the overlap point and measure the string length.
  • Use that measurement as the belt’s loop length.
• Write it down as: width x length (in inches).

• Belt won’t go on: length is too short.
• Belt goes on but is very loose: length is too long.
• Belt walks off the rollers: width is wrong, tracking is off, or rollers are worn/misaligned.
• Belt stalls under light pressure: belt is too long (low tension) or the drive system is slipping.

A correctly sized sanding belt keeps proper tension on the rollers, tracks straight, and transfers motor power efficiently. The wrong width or length can cause slipping, poor sanding results, and premature wear on rollers and bearings.

Once you have the width x length, use the model number 31-460 to search compatible belts and other replacement items on Sears PartsDirect.

Yes; a 4x36 belt sander works well for knife making tasks like profiling, rough shaping, and handle shaping, but it is slower and less precise for grinding long, even bevels than a 2x72 grinder. If you own a Delta 31-460 disc sander (type 2), it is a strong companion tool for squaring and flattening.

A 4x36 belt sander earns its keep on jobs where speed and perfect bevel geometry are less critical.

• Profiling the blade outline before heat treat
• Removing forge scale and surface rust
• Rough shaping handle scales (wood, G10, Micarta)
• Rounding handle contours and easing sharp edges
• General cleanup sanding between steps

These limitations are why many makers eventually move up to a 2x72.

• Lower belt speed and power than typical 2x72 setups, so stock removal takes longer
• Shorter belt length loads up faster, so belts need changing more often
• More heat at the edge during bevel grinding, especially after heat treat
• Less control for crisp plunge lines and consistent bevels on longer blades

Your Delta 31-460 is a disc sander, not a belt sander; it shines on flat, square, repeatable sanding tasks that support knife making.

• Start coarse (36 to 60 grit) for shaping; step up gradually for finish work
• Use fresh belts; dull belts create heat and waste time
• Quench often to protect temper and reduce burn risk
• Use light, consistent pressure to avoid waves and gouges

Knife grinding success comes down to control and heat management. A 4x36 can produce quality knives with patience and good technique; pairing it with a disc sander like the Delta 31-460 improves squaring, flattening, and cleanup.
