  1. Where are Eagnas-Maxline stringing machines manufactured?

    EAGNAS stringing machines are manufactured in Taiwan by Lily-Lee & Co., Ltd. Lily-Lee & Co, Ltd. is one of the largest OEM manufacturers of stringing machines in the world, and has been recognized as a full line supplier of stringing machines since 1981. See attached Good Product Design Award and Certificate of Excellence, issued by Taiwan government. EAGNAS is a registered trademark of Lily-Lee & Co., Ltd.

    Stringing machines sold by Alpha Sports (also known as New Tech Tennis) and Gamma Sports are imported from Taiwan and manufactured in Taiwan. The spring tension head of Gamma ST stringing machine is an OEM product of Lily-Lee & Co., Ltd. Ektelon Neos 1000 and Prince Neos 2000 models are also manufactured in Taiwan. Czech Sports stringing machines are imported from Czechoslovakia.

  2. Why do most professional stringing machines look the same?

    The professional stringing machines with manual crank spring tensioners are "clones" of the Ektelon H model stringing machine. The earliest clone of the Ektelon H model is EAGNAS EAG-500 model. In 1992 Czechoslovakia began to manufacture stringing machines. Czech stringing machines use a similar design to those manufactured in Taiwan.

  3. How many different type of mounting systems are available on current model stringing machines?

    There are only two types of mounting systems: the hold-down (press-down) mounting system and the suspension (air-support) mounting system. The suspension mounting system uses the 4 V-shaped side-support arms to support the racquet. See Figure 3-1. The head and throat mounting posts are only hold the racquet in place.

    For the hold-down mounting system, the supports are the head and throat mounting posts. See Figure 3-2. The side-supports are only to hold the racquet in place to prevent from distortion. The hold-down mounting systems are more secured and stable than the suspension mounting systems.

  6. What type of support systems are available on current model stringing machines?

    Current model stringing machines use one of three possible support systems: two-point, four-point or six-point mounting systems. Two-point mounting systems offer both head (tip) and throat supports. The mounting supports are at the 6 clock and 12 clock positions. See Figure 6-1.

    Four-point mounting systems also provide a pair of supports to the side of the frame to prevent the racquets from distortion. The side supports are at the 3 clock and 9 clock positions. See Figure 6-2.

    The six-point systems offer 2 pair (or a total of 4) side supports. The side supports are at the 2 clock, 4 clock, 8 clock, and 10 clock positions. See Figure 6-3.

  7. What are the pros and cons of six-point mounting system over the two-point mounting or four-point mounting systems?

    The six-point mounting system provides the maximum supports and eliminates any racquet distortion. But it has the less operating space. The four-point mounting system provides excellent side supports to eliminates the racquet distortion. And it has excellent the operating space. The two-point mounting system provides only head (tip) and throat supports. There is no side support. But it provides the maximum operating space.

  8. What is the six-point inside mounting system?

    There is no such thing as six-point inside mounting system. It is 2-ponit mounting system with 2 extra support points at head and throat mounting stocks. See Figure 8-1. The extra supports are at the 1 clock, 5 clock, 7 clock, and 11 clock positions. The purpose of the multiple side supports is to prevent the racquet from distortion. The inside supports could not prevent the racquet distortion. Besides that the support points of all the six-point system systems are adjustable to accommodate all types of racquets except this inside support system. The position of the inside suports could not be adjusted. Therefore, it only can mount certain racquets. It could not accommodate all types of racquets. Sometimes the inside supports will block the grommet holes. See Figure 8-2. This inside mounting system is created by a startup company. In May 2000 this company began to manufacture the stringing machines. (If you are thinking about a stringing machine with the six-point inside mounting system, check with the vendor about its inside supports. You'll need to know how many types of racquets this inside mounting system can accommodate.)

  9. What is the difference between floating clamp, fixed clamp, and swivel clamp model stringing machines?

    Models with a floating clamp (also called a flying clamp or speed clamp) tend to be less expensive, but they need to clamp two strings at a time to maintain proper string tension.

    Fixed-clamp stringing machines are categorized as either glide bar-clamp or swivel-clamp models. Glide bar-clamp stringing machines have two glide bar clamps attached to the glide bar tray table; swivel-clamp stringing machines have two swivel clamps attached to the swivel turntable.

  10. What kinds of materials are used to make stringing clamps?

    String clamps are typically made of two kinds of materials - either metal or composite resins. Metal clamps are better, but they are more expensive. Composite resin clamps are less expensive, but occasionally they won’t be able to hold the string over 65 pound tension.

  11. What is the difference between single-action and dual-action swivel clamps?

    The single-action clamp is a one piece assembly - both the clamp and the base are attached to the turntable. Unfortunately, the brake of the single-action clamp wears out with frequent use, requiring regular maintenance.

    In 1990, the Wilson Sporting Goods Co. introduced its Pro Staff (Prestige) stringing machine, which was manufactured in Taiwan. It utilized the single-action swivel clamp assembly, and it had brake problems (as mentioned above). Wilson Sporting Good Co. discontinued its production 2 years later. Current model stringing machines, utilizing the single-action clamp, are actually clones of this particular Wilson Pro Staff (Prestige) stringing machine. (If you are thinking about a stringing machine with a single-action clamp, check with the vendor about its brake assembly. You'll need to know how often the brake assembly needs to be serviced).

    The dual-action swivel clamp has two parts. One is the clamp itself; the other is the swivel base, attached to the turntable. Stringing machines that utilize the dual-action clamp offer the advantage of being relatively maintenance-free (they do not have the brake assembly problems of the single-action swivel clamp stringing machines).

  12. How many different types of dual-action swivel clamp bases are used on current model stringing machines?

    There are two types - those with spring-action levers and those without it. The dual-action swivel clamp bases that have spring-action levers are better, because they are both faster and much easier to use. Without the spring-action lever, the swivel base will occasionally catch the string.

  15. Why do the spring-action levers make stringing faster and easier?

    The dual-action swivel clamp bases with spring-action levers make stringing much faster and easier, because they have the built-in springs. You do not have to use muscle to operate them. You just need one-eighth turn to lock and release the base. Without the spring-action lever, you need to use muscle to latch the clamp base to the turntable. The disadvantage of not having spring-action levers is: not easy to latch the clamp base, need half turn to lock and release the base, time consuming.

  16. I have a machine without spring-action levers. Could I purchase spring-action levers and install them on the machine?

    No, you can not install the spring-action lever on the clamp base without spring-action function. They are not compatible. You have to get a set of the spring-action clamp bases to install on the turntable.

  17. What type of string gripper is better, the linear ball bearing string gripper or the cam (parallel jaw) string gripper?

    The linear ball bearing string gripper is better, because it is much quicker and easier to use. All the professional stringing machines use the linear ball bearing string gripper.

  20. Why is the linear ball bearing string gripper better than a cam (parallel jaw) string gripper? How does the linear ball bearing string gripper work?

    The linear ball bearing string gripper consists of two metal blocks, 16 balls and a gripper housing. Two metal blocks are mounted against these 16 balls, 8 balls are for each metal block. Therefore, these two metal blocks will be able to slide to the left or right side smoothly. When they are at the left side, the gap between these two metal blocks is narrow. When they slide to the right, the gap is wide. When you place the string between these two metal blocks, these metal blocks will slide to the left and grip the string automatically. There is no bolt needed or muscle to use. The linear ball bearing string gripper will grip the string even before the drop weight rod is pulled. Therefore, you only need to use one hand to operate the linear ball bearing string gripper.

    The cam string gripper will grip the string only when the drop weight rod is pulled. You always need to use two hands to operate the cam gripper: one hand has to pull the string with muscle, and the other hand to operate the drop weight rod.

    The cost of the linear ball bearing string gripper is much higher than the cost of the cam string gripper. All the professional stringing machines use the linear ball bearing string gripper.

  21. In terms of speed and easy of use, what type of stringing machine is better?

    The manual crank spring tensioner is much quicker and much easier than the drop-weight tensioner. The fixed clamp is better than the floating clamp. The glide-bar clamp is faster than the swivel clamp. The linear ball bearing string gripper is quicker and easier than the cam (parallel jaw) string gripper. The linear ball bearing stringing gripper with spring clutch (ratchet) is better than the gripper without spring clutch.

  22. What type of clamping system is the best, glide-bar or swivel?

    The glide-bar clamping system is faster than the swivel clamping system. But you have to use the floating clamps to handle the fan-patterned racquets. The swivel clamping system can handle fan patterns. But it will be slower. If you do not have the fan-patterned racquets, the glide-bar system will be better.

  23. Which stringing tools do I need in addition to buying the stringing machine?

    The basic stringing tools are the needle nose pliers, diagonal cutter, and tennis awl (or badminton awl). Most of the stringing machine's packages do not include these 3 basic stringing tools. Some packages include the stringing tools. For example, The ST-200 has 2 awls, 1 diagonal cutter and 1 needle nose pliers. The packages of the EAG-90 II, PRO HELPER and PRO CRYSTAL include these 3 stringing tools and one starting clamp.

    The ST-106 tool kit has the basic stringing tools.

    There is another very useful tool. It is the ST-101 string guide. It is a very useful tool for guiding string through the shared grommet hole.

  24. Is it necessary to purchase the tension calibrator?

    The stringing machine is adjusted and calibrated properly before shipping out of the factory. But the tension setting might be off due to the ocean shipment and inland trasnportation. It is a good idea to get a tension calibrator to check the tension setting and to calibrate if necessary. In the future you eventurally will need the calibrator to calibrate the tension head.

  25. What other accessories should I buy in order to string both the tennis and badminton racquets?

    You need to purchase the additional two badminton string clamps (PN-3091P, PN-3091, PN-7066, PN-1004, or PN-1007) and the badminton awl (BS-909). Some of the stringing machine's packages include the badminton string clamps, such as EAG-550, EAG-700, EAG-700A, EAG-860, EAG-900, EAG-960, EAG-2120 and EAG-3120.

  26. What is the difference between plastic stoppers, V-shaped side supports, half V-shaped side supports, K-shaped side supports, and large L-shaped shoulder supports?

    One V-shaped side support provides 2-point supports; one point is on the top edge of the racquet frame and the other is on the bottom edge of the racquet frame. Four V-shaped side supports will provide 8 supporting points. One half V-shaped side support provides 1-point support; the support is on the top edge of the frame. One K-shaped side support has 2 half V-shaped supports. The Large half V-shaped side support is for the tennis racquets; the small half V-shaped side support is for the badminton racquets. One plastic stopper side support provides 1-point support; the support is on the outer side of the frame. The large L-shaped shoulder support provides the top edge edge support.

  31. What's the difference between the universal V-shaped side support and the single V-shaped side support?

    The universal V-shaped side support has 3 V-shaped jaws: The large jaw is for oversized tennis racquets, the middle jaw is for mid-sized tennis racquets, and the small jaw is for badminton racquets. It can accommodate any shape of the racquet frame. The single V-shaped side support can only handle the tennis racquets.

  32. What is the difference between the X-shaped base and H-shaped base?

    The X-shaped base has 4 legs made of cast aluminium. See Picture 32-1. Although the gross weight is not heavy, but the material cost is higher. It is mandatory for stringing machine factory to design and create the mold in order to cast the legs. The H-shaped base utilizes 3 iron pipes welded together which forms the base. See Picture 32-2. Since a mold is not required, it is cheaper to produce a H-shaped base than an X-shaped base. The gross weight of the H-shaped base is heavier and may increase the shipping cost. The X-shaped base is far more attractive than the H-shaped base.

  33. I have never strung a racquet before. Is it difficult to string a racquet?

    We have the step by step illustrated stringing tutorial guides for all Eagnas stringing machines. You shall be able to follow the tutorial guide step by step and learn how to string the racquets. It is not difficult to string a racquet. Basically you have to go through the learning period.

  34. Will it take a long time to string a racquet for a first time stringer to use the stringing machine?

    It will take about 1 to 2 hours to learn and string the first racquet on any stringing machine. Then it will be much easier to string the second or third racquets.

  35. I break strings at the rate of about 1 per week and a half. What would be the best stringing machine for me to purchase?

    To choose a stringing machine, you might take into consideration the following factors.

    1. What is your budget? How much money would you like to spend on stringing machine?

      A.  About $100.00 to $200.00:
          You can get a drop-weight stringing machine with 2-point mounting,
          cam string gripper, 1 drop weight and 2 floating clamps.
    
      B.  About $200.00 to $300.00:
          You can get a drop-weight stringing machine with 6-point mounting,
          linear ball bearing string gripper, 2 drop weights and 2 floating
          clamps.
    
      C.  About $400.00 to $500.00:
          You can get a drop-weight stringing machine with 6-point mounting,
          linear ball bearing string gripper, 2 drop weights, 1 turntable
          and 2 fixed clamps.
    
      D.  About $500.00 to $1000.00:
          You can get a crank stringing machine with 2 to 6 point mounting,
          1 crank spring tension head, 1 turntable and 2 to 6 fixed clamps.
    
      E.  About $1000.00 to $5000.00:
          You can get an electronic stringing machine with 6-point mounting,
          1 electronic tension head, 1 turntable and 2 fixed clamps.
    

    2. How many racquets are you going to string every year?

    For example, you have 30 racquets to string yearly. The average stringing charge of the pro shop is about $20.00 per racquet. The total cost to string 30 racquets is about $600.00. Therefore, you could purchase a $600.00 stringing machine, and get your investment back within one year. If you have few racquets to string, you might get the less expensive stringing machine.

  36. I break strings at least 15-20 times a year. Do you think it is a good idea to purchase a stringing machine?

    Yes, it is a good idea to get a stringing machine. You will get your investment back within one year. Otherwise, you have to pay for the re-string service anyway.

  37. What is the difference between the drop-weight, crank, electric and electronic machines?

    The characteristics of the deop-weight machines are cheaper, constant pull, not easy to use, very slow process, time consuming, and relatively maintenance-free.

    The characteristics of the electric machines are cheap, constant pull, varied tension on every pull, AC voltage deviation affecting every tension pull, very slow process, time consuming, and maintenance needed.

    The characteristics of the crank machines are not cheap, not constant pull, precise tension on every pull, very easy to use, very fast process, and relatively maintenance-free.

    The characteristics of the electronic machines are expensive, constant pull, precise tension on every pull, slow process, and maintenance needed.

  38. What is the difference between the 1 drop weight and the 2 drop weights? Will there be a difference in the output?

    There is no difference between them. The 1 drop weight is only for the tennis racquets. The 2 drop-weight machines have 1 drop weight for the tennis racquets; the other drop weight is for the badminton racquets.

  39. Why do you recommend one oversized floating clamp and one regular size floating clamp? What is the advantage of one over the other?

    The standard package of the floating clamp system has one oversized and one standard floating clamps. The oversized clamp is very easy to handle the cross strings around the head and throat area because the gap between the strings are wide.

  40. What are the pros and cons of getting an electric machine and what makes it better than a manual?

    The electric stringing machine is not worth to mention. Please refer to the FAQ for the answer. The advantage of the electronic stringing machines is constant pull, no muscle needed and precise tension on every pull. The disadvantage of the electronic stringing machines is slow process, and maintenance needed.

    The advantage of the manual crank machines is precise tension on every pull, very easy to use, very fast process, and relatively maintenance-free. The disadvantage of the manual crank machines is not constant pull, manual crank needed.

  41. What is the difference between the Neon electronic tension head and Silent Partner electric tension head?

    The Neon tension head is the electronic tension head, which makes stringing much faster and easier:

    The Silent Partner tension head is the electric tension head:

    1999 to 2001 model:

    Present model:


  42. What is the difference between the DC motor and AC motor?

    The DC (direct-current) motor needs more hardware to operate:

    The AC (alternating-current) motor does not required to have the transformer, regulator and filter:


  43. Does the Hawk electronic tension head need 5 minutes warm up time?

    No, the Hawk electronic tension head utilizes the DC (direct-current) motor. It does not need any warm up tume at all. You just need to turn on the power switch and start to pull the tension immediately.

  44. Does the AC motor need 5 minutes warm up time?

    Actually the AC motor does not need any warm up tume at all. You can connect the power input and start to pull the tension immediately. But when the AC motor gets warm, it lowers tension. It means that when the AC motor is cold, it put higher tension. When the AC motor is warm, it put lower tension.

    On the front panel of Silent Partner's AC motor electric tension head, it indicates that "RUN FREE FOR 5 MIN TO WARM UP". What is the reason? Just because the AC motor gets warm, it lowers tension. Silent Partner uses this statement to cover up this fact.


  45. I notice that most of the table-top or portable stringing machines are the drop-weight type. Is there any advantage of drop-weight over the manual crank type?

    The drop-weight machines are much cheaper than the manual crank machines. Generally speaking, the price of the portable machines shall be lower than the floor models'. Therefore, most of the portable machines have the drop-weight tensioners. The advantage of the drop-weight machines is: simple construction, cheap, constant tension-pull. The disadvantage is: not easy to operate, time consuming.

  46. I have a drop-weight stringing machine. How can I upgrade it to manual crank spring tensioner?

    No, you can not upgrade a drop-weight machine to the manual crank machine. They have different construction. If you really want to upgrade it, you have to purchase the manual crank tensioner, tensioner track, etc. They are very expensive parts. And you have to do some engineering works.

  47. I have an Eagnas fixed clamp stringing machine (glide-bar clamp system). How can I change the machine to a swivel clamp machine?

    Yes, you can change it to a swivel clamp machine. Basically you have to purchase the turntable, two mounting stocks, two swivel clamp bases and two swivel clamps. But they are very expensive parts.

  48. It appears to me that the best clamping system is the glide bar, but you do not offer it on too many models. Can you put the Eagnas EAG-960 top on the Pro Helper electronic machine?

    The gilde bar system is a very good system. It offers the fastest clamping and the fastest process speed. But this system has been on the market for over 20 years. There were models with the EAG-960 turntable on the Pro helper. But the factory does not produce this configuration anymore.

  49. Is it necessary to calibrate the machine when I set it up?

    The stringing machine was calibrated in the factory. But we do not know whether the shipment will affect the tension setting. Normally you do not need to re-calibrate the tension setting of the tension head when you set it up. But it is a good idea to verify the tension setting by use of the TCG-100 tension calibrator.

  50. What's the difference between the oversized (PN-3089) and mid-sized (PN-3090) floating clamp??

    The oversized clamp (PN-3089) is much easier to clamp the cross strings on head or throat side of the racquet due to the wide distance between 2 strings.

  51. Which is better hold-down mounting system or suspension mounting system?

    The hold-down mounting system is more stable comparing to the suspention system; but the suspention system is faster.

  52. I was wondering if you could string racquets with fan shaped string patterns with a stringing machine that has glide bars not swivel bases?

    You can use 2 floating clamps to handle the fan-pattern racquet stringing.

  53. Do the stringing machines come pre-assembled, or are they to be self assembled?

    All the Eagnas stringing machines have been assembled and tested in production line. After passed the inspection by the quality control department, the stringing machines were disassembled into a few major components and packaged into boxes for shipment.

  54. What is the benifit of 6 point mounting system compared to a 2 or 4 point?

    The 6-point mounting system provides more supports on the shoulder to prevent the racquet distortion.

  55. I was wondering how many racquets your stringing machine is capable of stringing before it starts to wear out?

    This a a very good question. We can not give you a definitely volume answer. But you can Click here to view customers' comments on our stringing machines. There are lots of customers using our machine to string thousands of racquets.

  56. What are the advantages of glide bar vs swivel clamp?

    The glide-bar clamp system is an old configuration. It has been on the market over 25 years. It is fast; but it will not handle the tear-shaped racquets. The swivel clamp system is the new configuration. The speed is a little bit slow; but it can handle the tear-shaped racquets.

  57. What is the difference between portable and table-top machines?

    The portable machines are designed to be light-weight; the table-top machines are heavier than portable machines

  58. Would you refer a machine to a first time stringer, or is it a little to much for a beginner?

    There is no such thing called the beginner's model. All the machines will do the same job. You will need to consider what is your personal preference.

  59. Is it possible to do a side-by-side comparison of machine features on the website, especially the portable ones?

    You could Click here to view comparison of machine features on our stringing machines.

  60. What is the HAWK 10 made of?

    The body and 2 bases are made of iron pipes. The tensioner post is cast steel. The mounting stocks are made of cast aluminium. The swivel bar and string gripper are steel.

  61. Does the HAWK 10 need to be bolted or clamped to a working surface (table or other) during operation?

    No, the HAWK 10 does not need to be clamped onto the table. You just need to place the Hawk 10 on the table, then start to operate. No bolt needed either.

  62. Does the HAWK 10 need to be assembled before the first use or before every use?

    No, no assembly needed.

  63. Can the HAWK 10 string oversized racquets or only midplus sizes?

    The HAWK 10 can handle all the oversized racquets.

  64. Can the Hawk 10 be used to string badminton racquets?

    The tension range of the Hawk 10 stringing machine is from 20 pounds to 80 pounds. If your badminton racquet is in this tension range, you can use the Hawk 10 stringing machine to handle the badminton stringing.
