Bobbin Case Towa M Size TM3 Tension Gauge Tool Longarm

The Bobbin Case Towa M Size — TM3 Tension Gauge is the M-size bobbin case specifically designed for use with the Towa TM-3 tension gauge, allowing longarm quilters to measure and set precise, consistent bobbin tension readings. Using a dedicated bobbin case for tension measurement preserves the calibration of the production bobbin case and ensures tension readings are taken in controlled, repeatable conditions.

Frequently Asked Questions

Why use a separate bobbin case for tension measurement?

Using the same bobbin case for production and tension measurement introduces wear variability. A dedicated measurement case maintains known, stable characteristics for consistent Towa readings. The production case tension can then be set relative to the calibrated measurement readings.

Is this the same as the standard production M-size bobbin case?

It is the same M-size format but designated specifically for tension measurement use with the Towa TM-3. It is kept clean and well-maintained for reliable measurement readings.

What tension reading is standard on a longarm?

Standard longarm M-size bobbin tension typically reads approximately 180–220 on the Towa TM-3. Specific recommendations vary by machine, thread, and batting combination — consult your machine manufacturer for specific guidance.

Does the Towa TM-3 come with this bobbin case?

The Towa TM-3 and bobbin case may be sold separately or together. Check the current Linda’s listing for bundle availability.

How often should tension be checked?

Checking bobbin tension at the start of each project and after any thread or bobbin change ensures consistent results throughout production.
