Choose the tool for the question you have

Use the Finder before buying when drive type, stated capacity or table fit will decide the shortlist. Use the remaining-yarn calculator when you have the original label and can weigh the same yarn. Use the checklist while setting up a hank, swift and winder so a missed tie or unstable clamp is easier to catch.

The Finder and calculator keep inputs only for the current page session. The checklist saves checked items in this browser, can export a JSON copy and has a clear button. It does not create an account, sync between devices or send reminders. Every result is a starting point: confirm exact-model specifications and follow the manufacturer instructions before using equipment.

What to bring to each tool

For the Finder, measure the usable thickness of the table edge rather than its full decorative profile. For the calculator, use the label’s original length and weight plus the current yarn-only weight. For the checklist, read every securing tie before opening the hank and keep the yarn path clear. If winding has already gone wrong, start with the troubleshooting routes.
