If you’ve ever played with a yo-yo for an extended period of time, you’ve had problems with the string. Perhaps your string becomes knotted or tangled or perhaps it just snaps. Instead of buying a new yo-yo every time your string breaks, however, try to restring your own yo-yo.
The method for untangling a yo-yo string depends on the type of yo-yo you have. With a transaxle or ball-bearing yo-yo, just pull the two discs apart and untangle the knot. If you have a fixed axle, however, straighten a paper clip and try to insert the paper clip into the knot and loosen the know. Otherwise, use a pocketknife to cut the string below the knot. Whatever you use, be careful not to scratch the axle.
In addition, however, you should replace you string from time to time. Most strings last for six to eight hours (fewer if you’re doing tricks), but a new string will be more springy and will sleep better. To remove a string, let the yo-yo hang, and then spin it counterclockwise to widen the loop until it’s big enough to slip off the yo-yo. Then, cut a new string to the desired length, make a loop, slip it onto the yo-yo, and spin the yo-yo clockwise to tighten the loop over the axle. If you have a transaxle yo-yo, you should put in two to three loops.
Most yo-yo problems can be fixed by replacing the string, but in some cases, the yo-yo may not come up properly, which means you don’t have enough friction. If you have a transaxle yo-yo, try adding a little Vaseline to your axle (not the covering sleeve).
