Grind setting conversion
Fellow Opus vs Timemore Sculptor 064
Conical against flat — the Opus's scale curves where the other runs straight. The Opus is numbered 1–11; the Sculptor 064 is numbered 0–16.
| Opus | Sculptor 064 | |
|---|---|---|
| Brand | Fellow | Timemore |
| Scale | Numbered dial | Numbered dial |
| Dial range | 1 – 11 | 0 – 16 |
| Burrs | Conical | Flat |
| Espresso → filter | 3.3 numbers | 3.5 numbers |
| Filter → coarse | 5 numbers | 12.5 numbers |
The same number means different things
Both grinders use a numbered dial, which makes it tempting to copy a number straight across. Setting 6 sits at grind index 60.7 on the Opus but 50 on the Sculptor 064 — far enough apart to change the cup.
Converting a setting
If a recipe quotes a setting for one of these grinders, read across for the equivalent on the other. Rows are spaced evenly by grind size, not by dial number — on a conical burr those are not the same thing.

The shape of each dial
Where the connectors bunch, that grinder’s dial is compressed and single steps count for more. Comparing the two shapes tells you which gives finer control, and where.
Fellow Opus
Timemore Sculptor 064
Dialing in the Opus
Marketed as all-purpose, and it genuinely does cover more range than the Ode, but the espresso end is workable rather than good — expect to chase it. Where it earns its place is the coarse end: cold brew and French press come out notably even. If you bought the Opus mainly for espresso, dial it as a brew grinder first and judge it there.
Dialing in the Sculptor 064
Timemore's move upmarket into electric flat-burr grinding, with a genuinely usable espresso range unlike their hand grinders. Single dose oriented, and noticeably more consistent through filter than the C-series it sits above.
