Belt, disc, spindle & drum · review
The only machine on either half of this shelf to publish how fast it oscillates and how far.
The end of it Two machines in one, with the only oscillation figures on this shelf — and a belt size of its own.
Every figure below names its source. Each one is a manufacturer specification read off the listing itself. The judgments are ours.
The only oscillation figures on either half of this shelf.
Oscillation is the whole point of this machine. A spindle that only turns wears a band round its middle and polishes the work at that height; one that also moves up and down spreads the wear over the whole sleeve and leaves no band on the work.
Fifty-eight strokes a minute at 16 millimeters means the abrasive travels about 1.9 meters (6 ft) vertically every minute, on top of its rotation.
The published Scheppach OSM100 and Triton pages on this shelf publish the word and no number — and the OSM100 page names what oscillation delays: sleeves are a recurring cost and clog on resinous timber.
Opposite jobs, and most workshops want both.
A spindle sander cleans the inside of a curve. A belt sander takes material off a flat or a convex edge, to a line.
The published OSM100 page on this shelf is explicit about the limit of a spindle-only machine: does one job, inside curves, and does not replace a belt sander.
What the combination costs is motor. Three and a half amps driving both is less than the 450 or 650 watts the two European spindle sanders have for one.
A sanding machine is bought once and fed for years.
So the size of the belt, the disc or the sleeve it takes is a bigger decision than the motor: a common size is sold everywhere and cheaply, and an odd one ties the machine to one supplier at whatever price that supplier charges.
The published Scheppach BTS800 page on this shelf is recommended on exactly that ground — it publishes both consumable sizes, and both are the common ones — and the abrasives shelf in this catalog is where the arithmetic lands.
Four by twenty-four inches — 102 by 610 mm (24 in).
The published European machines on this shelf take 915 × 100 mm (36 × 3.94 in), which the abrasives shelf in this catalog stocks twelve of in one set.
So the width matches and the length does not. It is a common American size, sold widely, and it is not interchangeable with the rest of this shelf.
Half an inch, three quarters, one, one and a half, two.
Six pieces of 80-grit in the box: one for each spindle and one for the belt. Five throat plates, four rubber drums, a belt attachment, and somewhere on the machine to keep all of it.
The published OSM100 page on this shelf is credited for the same completeness — six sleeve sizes, drums and matching table inserts included — and the sleeve set on the abrasives shelf here exists because that is where the money goes afterwards.

Because oscillation is the whole point of the machine, and it is the one thing nobody measures. A spindle that only turns wears a band round its middle and polishes the work at that height; a spindle that also moves up and down spreads the wear over the whole sleeve and leaves no band on the work. Fifty-eight strokes a minute at 5/8 of an inch means the abrasive travels about 1.9 meters (6 ft) vertically every minute, on top of its rotation. The published Scheppach OSM100 and Triton pages on this shelf both publish the word oscillating and no figure, and the OSM100 page names the consequence in its cons: sleeves are a recurring cost and clog on resinous timber. Oscillation is what delays that.
One machine if the bench is full, which it usually is. A spindle sander cleans the inside of a curve; a belt sander takes material off a flat or a convex edge to a line. They are opposite jobs and most workshops want both — and the published OSM100 page on this shelf is explicit about the limit of a spindle-only machine: does one job, inside curves, and does not replace a belt sander. What a combination costs is motor: 3.5 A driving both is less than the 450 or 650 W the two European spindle sanders have for one.
That the belt comes from a different supplier than the rest of this shelf. Four by twenty-four inches is 102 by 610 mm (24 in), and the published European machines on this shelf take 915 × 100 mm (36 × 3.94 in) — a size the abrasives shelf in this catalog stocks twelve of in a set. So this machine's belt is a hundred millimeters wide like theirs, and 300 mm (11.8 in) shorter, which means it is not interchangeable. It is a common American size and sold widely; it is simply not the same size.
Between woodworking machines of the same category and nearby price. Shown: what they all state. A half-filled column says nothing.
