Frequently Asked Questions
- Why replace the OEM bobbin case with a Towa?
- Towa bobbin cases are manufactured to tight tolerances specifically for the demands of production longarm quilting. Many experienced longarm quilters report more consistent tension, better reproducibility with the Towa TM-3 gauge, and longer service life with Towa cases compared to standard OEM bobbin cases.
- Is the Towa 100100 compatible with my longarm machine?
- The Towa M-size bobbin case is compatible with all longarm machines that use M-style (Class M / 15J) bobbins. This includes most major longarm brands. Verify your machine uses M-size bobbins before ordering.
- How many bobbin cases should a production studio have?
- Most production studios keep at least 2–3 bobbin cases — one loaded and ready, one as backup, and one for calibration comparison with the Towa tension gauge. Having spares eliminates production stops caused by a damaged or dropped case.
- Does the Towa case work with Magna-Glide bobbins?
- Yes — Towa M-size bobbin cases accept all standard M-size pre-wound bobbins including Magna-Glide Classic and Delights.
- What maintenance does a bobbin case need?
- Clean periodically with a brush to remove lint from the tension spring area. Oil the bobbin case finger if recommended by your machine’s manufacturer. Handle carefully to avoid bending the tension spring, which would require case replacement.
