Sherwood OS-100 Spindle Sander — and the Amazon Alternative
Sherwood is Timbecon's brand, sold direct. An oscillating spindle sander is the machine class, and Triton's is the Amazon one.

Sherwood is Timbecon’s machinery brand, sold direct in Australia rather than on Amazon. The machine class is common and the Triton scored here is the version Amazon stocks.
Why oscillation is not a gimmick
A sanding drum that only spins does two bad things. The abrasive at one height does all the work and wears out while the rest of the sleeve is still fresh. And because the same grit passes the same point continuously, it burnishes and burns — leaving a glazed band on the workpiece that will show through finish.
An oscillating spindle moves up and down as it rotates, typically 15 to 20 mm of travel. Every part of the sleeve does some of the work, so the sleeve lasts several times longer, and no point on the workpiece sees continuous contact with the same grit, so it does not burn.
That is the whole argument, and it is the reason a drum chucked into a drill press is not the same tool.
Cast iron table
The table is what the work references against. A flat, heavy table keeps the edge square to the face; a thin pressed one flexes under hand pressure and rounds the edge over.
This is the specification to check on any machine in this class.
Sleeve economics
Sleeves are the running cost, and the small ones go fastest — a 12 mm spindle turns far more times per minute at the abrasive surface than a 50 mm one, so it wears out sooner while doing the fiddliest work.
Buy sleeves in multi-packs of the sizes you actually use, and rotate sleeves end for end when one end loads up.
Do not sand to the line
A spindle sander removes material fast. Saw close to the line, sand to it in light passes, and check often. The machine will happily take you past the line before you have noticed, and there is no way back.
What works
- The oscillation is the feature: the spindle moves up and down as it turns, so the abrasive wears evenly and cannot burn a groove into the work
- A cast iron table stays flat and gives the work something solid to reference against, which pressed steel does not
- Multiple spindle diameters mean one machine sands a gentle curve and a tight internal radius
What doesn't
- It is a single-purpose machine that takes up bench space for a job that comes up in bursts
- Sleeve costs add up, and the small-diameter sleeves wear out fastest because they turn the most times per minute
- Dust extraction on all machines in this class is mediocre — the port catches some of it and the rest goes on the floor
