Every figure below names its source. Each one is a manufacturer
specification read off the listing itself. The judgments are ours.
It tells you when you are pressing too hard
Which is the commonest error with a belt sander, and the only feedback mechanism
on either half of this shelf.
A belt sander cuts by belt speed, not by weight. Pushing down slows the belt,
loads the motor and digs a hollow — and the hollow is invisible until a finish
goes on it.
Every book on the subject gives the same instruction: let the machine’s own
weight do the work.
A warning that fires when the pressure is excessive is that instruction turned
into a feature. What it is not is a limit. It warns; the leaning still has to
stop.
Auto-tracking
A belt that wanders rubs the housing and shreds, or runs off the platen and
stops.
Manual tracking is a thumbwheel adjusted while the belt runs — reset every time a
belt is changed, and sometimes mid-pass as the belt warms and stretches.
The published WEN 6307 on this shelf publishes the same feature on a much smaller
tool: an auto-tracking belt system requiring no tensioning or adjustments.
Flush on one side
So the belt reaches into a corner, right up against a vertical face.
On a portable belt sander that is the difference between finishing an inside
corner and hand-sanding it, and it is published on one listing out of fourteen on
this shelf.
And no belt speed
Which is the figure a belt sander is judged on.
A slow belt burnishes. A fast one cuts. This page publishes six amps instead,
which is an input rather than an output.
The published Makita 9403 page on this shelf has the identical gap in its cons —
no motor rating and no belt speed published — and three of the seven American
machines here do publish one.
The abrasive is the running cost
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.
Three by eighteen inches
Seventy-six by four hundred and fifty-seven millimeters, which is a common
portable size and is not the size of anything else on this shelf.
The published Makita here takes 100 × 610 mm (3.94 × 24 in). The WEN 6502T takes 4 × 36 in. The
Scheppach machines take 915 × 100.
Four machines, four belt sizes, and only two of them share one.
