I’m at the moment studying string. One matter I don’t fairly perceive is knots. What’s one of the best ways to make a tie-off knot? If you happen to’re stringing in two items, how do you suggest tying a knot that begins the crosses?—Peter S.

These are necessary questions, Peter. Knots are an important endpoint when stringing. Incorrect approach can compromise a string job by inflicting it to lose pressure. Furthermore, in worst case situations, unhealthy knots may even trigger a stringbed to collapse utterly—not one thing you wish to occur while you’re in the course of a match.
So let’s begin along with your first query: Tie-off knots. For many stringers, these knots, which safe the ends of major strings and/or crosses downstream of pressure, are greatest tied utilizing a double half hitch. Because the U.S. Racquet Stringers Affiliation makes clear, “To tie a half hitch, keep in mind the phrase ‘OUT.’ Thread the string Over, Beneath after which By means of—then repeat the process once more and also you’ve accomplished the knot.”
Certainly, doubling up on the half hitch is necessary, as single hitch knot is liable to return unfastened or sink deep into the grommet, as a consequence of its easy configuration and small dimension. When putting in a really skinny string, like an 18 or 19 gauge, it could even be advisable to tie a triple half hitch—that’s, three consecutive half hitches—simply to be sure that the knot doesn’t slide down into the grommet gap.
Additionally keep in mind, after tensioning the final major or cross, to go away your self not less than 10 to 12 inches of string to tie-off with. There’s nothing extra irritating than being unable to complete the knot, since you’ve clipped the string too quick or measured your entire size of string incorrectly. To tighten the knot, the most effective strategy is to make use of hand-held pliers. Whereas some use the stringing machine to pressure knots, if not achieved with care, the tensioner can place an excessive amount of stress on the knot, inflicting it to interrupt. Lastly, after the knot has been secured, clip the tail down beneath the racquet’s sidewall, in order that it’s about 1/eighth to 1/4th an inch lengthy. Reduce the size too lengthy and depart it above the sidewall, and the tail might reduce the participant; reduce it too quick, and the knot might slip misplaced.
As to your second query: A distinct knot, other than the half hitch, is required when tying knots initially of crosses. (These knots are solely essential, as you be aware, when working with two items of string.) Beginning knots, in contrast to tie-offs, are designed to be bigger to, once more, stop towards slipping down into the grommet gap, in addition to resist breakage upon first tensioning the string. (“A beginning knot,” the USRSA explains, “doesn’t place stress on the anchor string.”)
Stringers, over time, have devised quite a lot of completely different beginning knots. The “figure-eight” and “fishing” knots are two which are generally used; the previous is among the many bulkiest, and is nice for stringing racquets with massive grommets, whereas the latter has the benefit of being, in USRSA phrases, “free floating,” which means that “it may be pulled towards the body with out tying the knot to an anchor string [as] you’re tying it towards itself.”
For diagrams of the usual tie-off knot, a.okay.a. the double half hitch, in addition to three viable beginning knots, see the above diagrams, excerpted from the USRSA’s Racquet Service Methods Guide.
