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.
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.
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.

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.
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.
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.)
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.
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.
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).
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.

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.
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.
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.

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.
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.
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.
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.
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.
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.
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 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.
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.
| Model | Material | Weight | Capital Investment | Material Cost | Shipping Cost | Appearance |
| H-shaped Base | 3 iron pipes welded together | Heavy | No | Low | High | Not great |
| X-shaped Base | 4 cast aluminium Legs | Light | Yes | High | Low | Attractive |
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.
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.
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.
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.
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.
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.
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.
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.
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:
The importer, Deuce Industries Ltd. in Canada (Silent Partner), claims that the red and gray color machines are as his own colors. Aside from Silent Partner machines, no other machine can use these colors. The Silent Partner also claims that any other machines coated with red and gray colors are fake and imitated. Let us check how many machines are in red and gray colors. In 1984 Winn Inc. imported the Winn Pro stringing machine (two color options: blue and gray, or red and gray). In February 1985 Maxline imported and displayed EAG-700 stringing machine in New York trade show. The EAG-700 has two color options: blue and gray, or red and gray. In 1985 Gamma Sports imported the red and gray 4000 stringing machine. In 1988 Maxline imported the red and gray EAG-960A stringing machine. In 2000 Deuce Industries Ltd. in Canada imported the red and gray DG stringing machine. Actually the stringing machine factory has the typical colors for all the machines. The typical colors are black, navy blue, blue, gray, purple, red, yellow and white. The gray color is the typical color for turntable and tool tray. If the importer does not specify the colors, the factory will ship the machines with the typical colors. The factory will print the importer's trademark and/or logo on the base for portable and table-top machine, on the column and the cover of the crank tension head. Currently Maxline has the following red stringing machines on the market: Eagnas DEN-3600, Eagnas 10, Hawk 20, Hawk 40, Hawk 880, Hyper 320, Hyper 480, Neon 21, Neon CX, Neon CX21 and Neon CXS.
| Time Period | Silent Partner's FAQ#2 |
| From 1999 to December 2000: During this period the Silent Partner just began to import and market the electric stringing machines. The Silent Partner emphasized these type of tensioners were very popular in the past. It implied that the electric tensioners were popular at that time. |
2) What is a "spring and brake" stringing machine? A machine with a spring and brake tensioner relies on a hand operated crank to pull the string. A spring deflects against the tension being applied to the string. When the pre-selected tension is reached, a lever is tripped stopping the tensioning operation, and a brake is engaged to hold the tension in the string. When properly calibrated, spring and brake tensioners are usually very accurate and they have been very popular in the past. Spring tensioners are a definite improvement over drop weights and they usually cost a fair bit more. Stringing machines with these spring and brake tensioners cost in the range of about $400 to $1,000. |
| From January 2001 to December 2001: In order to futher promote the electric tensioners, the Silent Partner needed to further degrade these type of tensioners. |
2) What is a "spring and brake" stringing machine? A machine with a spring and brake tensioner relies on a hand operated crank to pull the string. A spring deflects against the tension being applied to the string. When the pre-selected tension is reached, a lever is tripped stopping the tensioning operation, and a brake is engaged to hold the tension in the string (for this reason, these machines are also known as "lockout" machines). When properly calibrated, spring and brake tensioners are accurate although variations in the speed with which the operator turns the crank cause variations in the final tension of the string. Spring tensioners are an improvement over drop weights and they usually cost a fair bit more. |
| From January 2002 to Present: The Silent Partner began to import and market the "spring and brake" stringing machines. The Silent Partner needs to promote these type of tensioners. |
2) What is a "spring and brake" stringing machine? A machine with a spring and brake tensioner relies on a hand operated crank to pull the string. A spring deflects against the tension being applied to the string. When the pre-selected tension is reached, a lever is tripped stopping the tensioning operation, and a brake is engaged to hold the tension in the string (for this reason, these machines are also known as "lockout" or "instant off" machines). When properly calibrated, spring and brake tensioners are very accurate and allow fast stringing, which is why they are extremely popular in pro shops. Because these machines "lockout" as soon as they reach the reference tension, professional stringers usually set the tension about 10% higher than they do with "constant pull" machines (see FAQ 11 for an explanation of the difference between instant off and constant pull machines). |
In 1997 the stringing machine factory (Lily-Lee & Co., Ltd.), developed a new 6-point suspension mounting system. Then there are two series machines with this mounting system that were introduced into the market, the Neon and the Hyper series. The Neon series machines are electronic machines, such as Neon 21, Neon CX, Neon CX21, Neon CXS and King 3115H. The Hyper series machines are drop-weight and manual crank machines, such as Hyper 50, Hyper 100 and Hyper 500. Basically, the Hyper series machines are made for the European market. In September 2000 the XP series machines were introduced to the market, such as XP-45, XP-46, XP-600, XP-601, XP-650, XP-651, XP-8200S, XP-8201S, XP-8600S and XP-8600T. The XP series machines are designed for the Japanese and south Asian markets. In October 2001 the Hyper 480 was introduced to the market. The Hyper 480 is identical to the XP-650 except the colors. The XP-650 has the gray and light yellow colors; the Hyper 480 has the red and gray colors.

In 1999 Deuce Industries Ltd. in Canada began to import the stringing machines from the factory (Lily-Lee & Co., Ltd). The Silent Partner imported the base, mounting system, clamps, accessories, and shipping box of the Eagnas Hawk 20 stringing machine from the same factory. Then by attaching an electric tension head, an e.stringer machine is created. See the e.stringer clone history.
In May 2000 an ex-employee of the stringing machine factory (Lily-Lee & Co., Ltd.) began to copy Eagnas Hawk and Hyper series machines. Later on Silent Partner imports stringing machines from this startup company (Xpider Co.).

The answer is Eagnas Hawk 800 strining machine. Since 1997 he uses the Eagnas Hawk 800 to learn and to string his and his son's racquets. Even in 1999 he imported the stringing machines from this stringing machine factory (Lily-Lee & Co., Ltd.). But on the Silent Partner FAQ#5 mentions: One supplier of low cost stringing machines has acquired a very bad reputation for poor quality and customer service, and it is wise for customers to limit their shopping to reputable brands. In October 1997 he purchased the Eagnas Hawk 800 stringing machine described as poor quality and customer service. But two years later strange enough was he even importing those so-called poor quality stringing machines and marketing to the public. It is very ironic. What certifies his critic as a valid statement. See how he gets the stringing knowledge from Eagnas Hawk 800 stringing machine as follows.

I have seen your ad in TENNIS as well as your web page. I am looking to buy a stringer for my 10-year old son and the Hawk 800 looks interesting. Can you snd me more information about the stringer as well as about your company (your location and other products you may carry). |
| September 28, 1997 |
I am interested in buying an upright stringer that I and my 11 year-old son can use. I have looked at your FAQ information and all your models. The Hawk 800 looks like a great deal, but I would like to know what more I will get if I spend more for one of your more expensive non-electronic models. I have to assume that I would be paying more for something.
Your literature does not make clear what that would be. |
| September 29, 1997 Silent Partner uses this information as FAQ#16. |
The more expensive models, such as EAG-90 II and STAR J312, have the heavy-duty string clamps and the spring-action swivel clamp base. |

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.
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.
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.
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.
You can get string patterns from the racquet vendors, or you can get them from the internet. Here are some locations:
Dunlop Sports Racquet Stringing InstructionsA 660 ft. reel will string about 20 racquets.
No, we do not have the string comparison chart.
There are only few string manufacturers around the world. They are the OEM string suppliers to all the importers and wholesalers. The importers will create a special trade name for a particular string to distinguish it from the other importers' identical strings. By this way the importer can set up his own price structure. But we have no way to know which string is identical to the other strings. The string manufacturers will not supply this kind of information to the importers and wholesalers. It is their trade secret.
Therefore, one importer can mark up his string price for $15.00 per set. The other string suppler will sell this identical string with his own trade name for only $5.00 each. The difference is that the high-price string supplier have to recruit his heavy advertisement expensive, higher overhead cost, etc.
No, we provide the best prices on the stringing machines and strings. The string package means "forced purchase". The customers pay the higher price to get the stringing machine and string package.
The nylon is durable, but the performance is not that great. The Kevlar is very durable and the performance is better than the nylon. The Synthethic gut is not durable; but the performance is better than the nylon and kevlar.
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.
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.
No, no assembly needed.
The HAWK 10 can handle all the oversized racquets.
EAGNAS 10 stringing machine has the linear ball bearing string gripper with spring clutch (ratchet) and V-shaped side supports. The DEN-3600 only has the linear ball bearing string gripper and does not have the V-shaped side supports.
HAWK 800 has 2 dual-action swivel clamps. The swivel clamp base does not have the spring-action lever. It can handle fan-patterned racquets. But it will be slower than the EAG-700.
EAG-700 has 6 glide-bar clamps: 2 oversized, 2 standard tennis, and 2 badminton. You have to use the floating clamps to handle fan-patterned racquets. It will be faster than the HAWK 800.
HAWK 800 and EAG-700 have the identical crank spring tensioner. The only difference is the color of the cover. HAWK 800 has the black color; EAG-700 has the gray color.
HAWK 80 has 2 regular dual-action swivel clamps. The swivel clamp base does not have the spring-action lever. The string gripper does not have the ratchet device.
Y12-3 has 2 heavy-duty, dual-action swivel clamps. The swivel clamp base has the spring-action lever. The string gripper has the uni-direction clutch (ratchet device).
Y12-3 will be better, more convenient and faster than HAWK 80.
The PRO HELPER has the linear ball bearing string gripper, motor, chain, and electronic tension control circuit board. It has the more complex electronic design and construction. It is the floor model.
The HAWK 880 has the cam string gripper, motor and LED readout. It has the simple design and construction. It is the table-top model.
Therefore, the Hawk 880 has the complete different design and construction from the PRO HELPER.
The mounting system of the Neon 21 is called the suspension mounting system. The supports are the 4 V-shaped side-support arms. The head and throat mounting posts are only hold the racquet in place.
The other mounting system is called the hold-down mounting system. The supports are the head and throat mounting posts. The side-supports are only to hold the racquets in place. The Hawk 880 has this mounting system.
The Hawk 880 is identical to the Neon 21 except the mounting system. The Hawk 880 has the hold-down mounting system; the Neon 21 has the suspention mounting system.
Functionally the Neon 21 is compatible to the Neon CX except the cover and the base. The Neon CX has the pretty plastic cover and the steel base; the Neon 21 has the metal case and the cast metal base. The advantage of the Neon CX is that it can be mounted on the floor stand and can be converted into the upright model. The Neon 21 can not be mounted on the floor stand.
The Neon CX21 is identical to the Neon CXS except the base. The Neon CX21 has the H-shaped base; the Neon CXS has the X-shaped base.
The Hawk 800 stringing machine is identical to the GA stringing machine except the turntable and the color. The Hawk 800 has the cast turntable and the black color. The turntable of the GA is made from the sheet steel metal. And the GA has two swivel clamp tracks mounted on the turntable. The GA has the silver and blue color.
The Hawk 80 stringing machine is identical to the GC stringing machine except the turntable and the color. The Hawk 80 has the cast turntable and the black color. The turntable of the GC is made from the sheet steel metal. And the GC has two swivel clamp tracks mounted on the turntable. The GC has the silver and blue color.
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.
