The Effective Use of the Bobbin In our last column, we talked about thread control. Let’s expand on that a bit by going into more detail about fly tying bobbins and how to use them. Learning to use the bobbin effectively is the essential foundation upon which most critical fly tying procedures build. You should devote sufficient time to practice to ensure that you have a good command of this vital skill. As with any other issue in fly fishing or fly tying, you will encounter many different opinions regarding the selection and use of bobbins. I can only offer my own take on this subject, for what it’s worth. I recommend a spring steel, “Matarelli-style” bobbin with a ceramic or titanium insert. A bobbin of this type will usually retail for a cost in the neighborhood of $8 to $14 and is well worth the price. The only non-insert bobbin I can recommend is the genuine Matarelli brand. Cheaper bobbins without inserts are available, but increased problems with thread breakage make them a poor bargain. As a novice tyer, you do not need additional frustration caused by inferior tools. You can buy very fancy bobbins, at fancy prices. Bobbins are made that are spring-loaded and will automatically “reel in” excess thread. You can also find bobbins with mechanisms that allow repeated tension re-adjustments. I certainly wouldn’t discourage you from experimenting with such things if you are so inclined, but I don’t use them and don’t find them necessary. I know several professional fly tyers who also don’t bother with these “bells and whistles.” In my opinion, so-called “adjustable tension bobbins” limit the tyer’s ability to change thread tension as needed for different steps in the tying of a fly and interfere with the development of a tyer’s touch and feel with the working thread. From this point forward, I will assume that you have acquired a Matarelli-style bobbin and that it’s in new condition. The first thing you need to do is adjust the tension by carefully bending the spring steel arms. I’ve never seen a new, off-the-shelf bobbin that did not require significant tension adjustment. Otherwise it is impossible to feed thread from the spool without breaking it or maybe even bending the hook in the vise! To adjust your bobbin, first install a spool of thread between the arms. Hold the bobbin by the base of the tube, grasp the thread and try pulling gently. You may not be able to move the spool at all before the thread breaks. Remove the spool from the bobbin. Brace both thumbs against the point at which the arms meet the tube, and gently bend both arms outward slightly. As you do this, be careful not to put stress on the solder joint there. Replace the spool and test again. Repeat this bending and testing procedure until the desired tension is achieved. Go slowly, and don’t bend too much at a time. It’s better not to overshoot the desired tension and have to try to re-tighten. Once your bobbin is properly adjusted, you should never have to change it so long as you stick with standard size thread spools. My preference is to reduce the tension sufficiently that lightest thread I plan to use will feed easily without risk of breakage. Once you’ve adjusted the bobbin, you’ll need a way to pass the end of the thread up through the tube. Some tyers use what’s sometimes referred to as the “suck method.” They will start the end of the thread into the base of the tube, then put the other end of the tube between their lips and suck madly until the thread comes through. I have done this a few times when I did not have a bobbin threader of some kind handy, but it’s not my first choice. It doesn’t always work, and when it doesn’t it’s usually because the tube has become partially obstructed with wax that’s built up from the tying thread. You sometimes you wind up inhaling particles of this wax as you try to suck the thread up through the tube. I used to like using the little blue monofilament loops sold in drugstores as dental floss threaders. With them, there was no worry about scratching the inside of the bobbin tube, as with the commonly available wire threaders. Unfortunately, many bobbin inserts now do not run the full length of the tube, but consist of just a plug at each end. This creates an internal ledge that the dental floss threader tends to hang up on. So I’ve been forced to resume using the stiffer wire threaders, which are easier to get past the insert plugs. Simply insert the wire loop down through the bobbin tube from the tip toward the spool. Pass the thread through the wire loop and pull it up and out the end of the tube. The above-mentioned wax build-up inside the bobbin tube can become serious enough to require remedy. The Griffin company, a manufacturer of tying tools, markets a set of three implements consisting of a bobbin threader and two tube cleaners. The cleaners are simply a length of stiff wire sized to be just a tiny bit smaller than the inside diameter of common bobbin tube sizes, with a plastic bead on one end to serve as a handle. Whenever I notice a lot of thread breakage, the first thing I check is to see if the bobbin tube has a wax build-up. It’s pretty amazing to pass a cleaner wire through the tube and watch it punch out a little plug of wax. Be careful with the newer bobbins, though, that you don’t punch the insert out of the end of the bobbin tube. Sometimes a wrap of thread will slip off the spool and get around the arm of the bobbin. Many people pull the thread back down and re-thread it, or remove the spool to get rid of the offending wrap. Neither of these things is necessary. All that’s needed is to take the loop of thread down off the arm and take a turn around the spool to put it back in the proper orientation. How to hold the bobbin is another important issue. I’ve watched many beginners simply ignore the bobbin, grasping the thread with their fingers and allowing the bobbin to dangle uselessly below. As intuitive as this may seem, it’s not a good approach. You should use the end of the bobbin tube to guide the thread onto the hook. Thread placement is much more accurate, and rough fingers will not fray the tying thread. I like to let my index finger rest in the little notch formed by the wire of the bobbin arms where it joins the tube. The thumb then falls naturally on the opposite side of the tube. Allow the thread spool to rest in the palm of the hand. Use the middle, ring, and pinkie fingers to hold the spool and stop it from turning when you want to prevent thread from feeding out. When you wish to feed thread out, simply relax the grip on the spool with these fingers and pull gently allowing the spool to rotate. Once you have adjusted your bobbin to proper tension, a good drill is to grasp the thread with your off-dominant hand and gently pull down with the bobbin allowing thread to feed out. When you’ve fed about a foot of thread, grasp the thread spool and rotate it against the tension of the thread, reeling the thread back onto the spool. Repeat this exercise several times. This is a very good way to get comfortable with the bobbin and work toward having proper handling become second nature. Best control of the thread while tying is achieved when there is about one inch distance between the hook and the tip of the bobbin tube. As you make your thread wraps while tying, develop the habit of periodically feeding thread out to maintain this approximate distance. You should not be making huge circles with the bobbin around the hook, nor should you wind the tip of the bobbin tube right up to the hook. While tying, you will always hold the bobbin in such a way as to either feed or not feed thread. There is no middle ground, it’s either yes or no. The amount of tension applied to thread and materials is determined by how hard you pull against them with the bobbin hand when the spool is held firm and not allowed to rotate. Generally, you will want to bind materials to the hook as firmly as possible without breaking the working thread. You will quickly learn to judge appropriate tension. Using this method allows you to have precise control over how much tension is applied to the thread at any step of tying a fly. I hope that this information proves useful to you. Good tying!
