How to wax a bowstring and perform other basic string maintenance
Think of your bowstring as the engine that drives your bow, whether it’s a compound, a recurve or a longbow.To get energy out of the bow to propel an arrow, you must put energy into it. And to do that, you have to draw the string.Your car engine needs regular maintenance to keep up with wear and tear. Same goes for a bowstring.(And our discussion of bowstrings here includes the cables on a compound bow.)WAX ON, WAX OFFThe simplest thing you can do to maintain your string is to wax it. How often should you wax it? That depends on many factors – humidity, how often you shoot, the presence of dirt, etc.Basically, you should be able to touch your string at any time and feel a slight tackiness to it. That’s a well-waxed string. If it feels slick and dry, give it a shot of wax.When you see “hairs” start to stick up from the strands of the bowstring, like the string is getting furry, it’s time to apply some wax. If you see individual strands sticking out, that’s a damaged bowstring, and it has to be replaced.Applying wax to a bowstring is simple. Most bowstring wax comes in a stick, like deodorant. Just rub the stick up and down the string to apply wax, and then rub it into the string by running your thumb and forefinger up and down the string. Use enough pressure so that your fingers heat up. That will cause the string to melt between your fingers as you work it up and down the string.When you’re done, there should be no visible chunks of wax.Do not apply wax to any serving material. The wax can work its way under the serving material, causing it to slide and separate.Be sure you don’t over-wax your string. This can adversely affect performance.PROPER SERVINGClosely inspect all of the serving on your strings and cables. Serving is thread that’s tied in over top of the string.All bowstrings have serving in the nocking area. The ends of strings, where they attach to the cams or the limb tips usually are served. Also, most compound strings and cables have serving anywhere they touch a cam, roller guard or string stop.You want the serving to sit in tight coils, neatly stacked one on top of the other, on top of your string.Any separation in the serving in the nocking area must be addressed ASAP. This can affect accuracy.Slight separation of the serving coils in other places isn’t a pressing concern, but it’s only going to get worse, and it will have to be fixed at some time.If the serving breaks, it must be fixed no matter where it is on the string or cable.Your local archery pro shop can fix serving issues, or you can learn to do it yourself. Reserving some area on compound bows, however, will require a bow press.Be aware that serving thread comes in different thicknesses. Serving thickness is most critical in the nocking area, since you want to use whatever thread allows for proper nock fit.STRING STRETCHRecurve archers will want to constantly measure their bow’s brace height to check for string stretch. The brace height is the distance between the throat of the grip and the string. Over time, the brace height on a recurve can shrink if the string stretches – especially within the first few days after a new string is put on a bow.In that case, unstring the bow and add twists to it until the brace height is where it needs to be. Twisting the string will increase the brace height.On compound bows, archers need to check cam timing to determine if there’s been any stretching of the cables. You want the cams on dual-cam bows to roll over perfectly in synch. If they are out of synch, accuracy will suffer. Twisting a cable will bring out-of-synch cams back together.If you have a single-cam bow, check with the manufacturer to find out how to determine proper cam position for your bow. The fix for cable stretch still will be to twist a cable.
