OK.
The elongation figures of a string show the most important quality of a string, it shows what the player feels on ball impact and also has an important influence on the durability of a string.
Which one of these is correct?

Yes this is very strue.
But when you compare strings the sbs has to be the same because that is what the player feels most.
@Stringway Official,
I’m pretty sure I searched throughly and could not find a straight answer. This is for the T92 clamp system. I know it is pretty obvious but I need to ask before I make a decision on a stringing machine.
Question: what prevent the base of the clamps from moving in the opposite direction of the tension after you clamped a string and let go of the string from the tensioner? I saw a thread from someone saying that he owns a ML100 with T92 clamp system and he said that after closing the clamp (without holding any string), he could move the clamp in both Y and X axis. The T98 is a double action clamp so I understand that one action is to secure the base of the clamp to the turn table. Thanks.

It is a very logic question funny that we did not get it more, while we make the system since 1992.
The system locks because of the relation between the distance between the string and the shaft and the length of the guiding bush. The bigger this distance the more difficult the bush will slide.
Therefore it is important to push the system around low.
For minimum drawback we advise to push the clamp back before closing it.
The good thing about this is that there is no mechanism that can wear so very old systems still work very well.
The Pacific machines use this same principle
When you have anymore questions please let me know.

@Stringway Official,
Who is your distributor in the US? New Tech Tennis? Is there a coupon or discount from the factory/distributor I can use to purchase a stringing machine? Unfortunately, tennis is an expensive sports and everything that comes with it has a big tag price. So whatever you can do to help, is well appreciated. Thank you

Yes there are discount options but I am not allowed to tell about them on this forum as a company official.
Please send me an email to stringway.fred@gmail.com and I will tell you more.

Can you please post a full list of the conversion range from the Kg/cm to RDC, for frame stiffness, based on RDC ratings here? For example, I have some frames that are supposed to be around 90 stiffness, but I couldn't reverse engineer the formula to figure out what that converts to on your Kg/cm scale.
Additionally, some of the numbers listed, see highlighted in pink numbers, in the Excel Spreadsheet you posted do not match the scale on the right side.
7.09 = ~50 RDC listed as 61
7.51 = ~53 RDC listed as 61
9.24 = ~62 RDC listed as 66

Some more information about this:
The table shows tests done by a stringer who had all systems so he could compare, so we do not know the reason for the differences.
Important to know is the following:
- The RA system measures from 100 downwards. This means that the deflection for 90 (=10) is 3 times smaller than for 70 (=30).
So a racquet with an RA value of 90 is 3 times stiffer than one with RA value 70.
I have never heard of racquet with RA80 or higher.
This means that the RA scale is very unlinear and less accurate for higher RA values.
The formula that made the graph is RA=100-351/ST2
Meaning:
For ST2 = 12 >>> RA=70.7
For ST2 = 35 >>> RA=89.9

HAPPY BADMINTON STRINGER
Hi guys,
Just want to share this message with you coming from a badminton stringer with a ML100-T92.
Of course this kind of feedback makes a designer proud and happy.
Hi Fred,
Its Marc, I ordered the ML100 stringing machine with badminton racket support set a few weeks ago and i just wanted to say that the stringing experience is simply very nice. I have to admit, I don't have any experience with other stringing machines, so I cannot really compare, but I don't see how this machine can be improved in any way. Everything is so thought through and just works perfectly, just like a well oiled machine (haha
). Even though I study engineering, it is still a mystery to me how you managed to make the drop weight lock out in the upwards position only when no string is currently clamped in the pulling system. It is just amazing.

I would like to share the message I received this morning.
It may prove that you do not need a big machine to string accurately.

Hi guys,
A Dutch owner of a very old Ektelon machine contacted us because he lost the racquet supports of his machine.
I would like to help him and make the parts, but I need the dimensions of the parts.
Is there anybody with an Ektelon and a caliper who can make a sketch of the parts with the dimensions.
Thank you
Fred

Clamp systems T98 and T92.
Every now and then people find pictures of our double action clamp system and ask about it;
Hereby some more information:
We do not make the T98 system anymore because the T92 system is better in every detail:
- It moves around easier.
- The guiding system locks “automatically” without any mechanism.
- There are no parts that wear, even very old (30+ years) still work without a problem.
- It is stiffer so less deformation and less loss of tension.
- The clamps are the same.
If you have anymore questions let me know

Quote From another thread:
This week a customer sent a Stringlab 2 back because he thought that the system could measure the stringing tension instead of the string bed stiffness.
The advantage of measuring the SBS is that it is a reference for the playability of the string bed.
Disadvantage of measuring the stringing tension is that the tension is different in every string:
- The tension in the mains is higher than the set value because these are tensioned extra by the cross strings.
- The tension in the crosses is lower because of all the friction with the crosses.
The translation between SBS and stringing tension depends on the size of the racquet and the number of strings, this is “built in” our online Tension Advisor.
On page 3 you enter the racquet specs to calculate the tension for a certain SBS

We also have it in KG’s if you are interested

Trick for the MS140LS on a stand.
The light weight MS140 can be used on a stand but it is important to know how to use it.
When the machine is used on higher tensions the lifting force on the lever may lift the stand off the floor.
You can prevent this in 2 ways:
- Add extra weight in the tube of the stand.
Like a long tube (long stocking) with some kg’s of grind in it.
- Put your foot on the toe of the stand. The front leg is supplied with protection.
To fix the machine on the stand there is a key hole in the bottom of the frame.

CALIBRATION OF THE STRINGLAB 2
A German customer was worried about the calibration of his Stringlab 2.
The picture shows how we calibrate every system with 2 calibration springs.
Once the calibration is done there is no reason that it would change.
We sent a calibrated coil spring to the customer.
This morning we received his message:
IF you use a Stringlab do not worry about the calibration.
If you have questions let me know.

Hi,
How narrow the ms140’s mounts can go ? I have a Sabre Tennis racquet from functional tennis (37 inch sqft), i’m wondering i can mount this racquet on the ms140 or not.
Thank you.

the racquet is 37sq in, my bad, it’s a training racquet with a tiny head size.

For a training racket wil a small head why not just hand string it?

These pictures show the maximum and minimum racquet head length which fits on the MS140LS-tennis.
For the badminton machine hese dimensions are 100 mm smaller.
The recommended tension for the racquet is 25-35 lbs so i think it is best to string with a machine for a consistent result.

Shipping the MS140 to Australia is 45 % cheaper than the ML100-TH-Th18.

G.O.A.T.
I wish the MS140 had been available when I first purchased my ML90. I love my ML90 and have had it for over 10 years, but I do not have an area designated just for stringing, so every time I want to string one of my racquets, I have to lug my stringer out of my closet and put it on my kitchen counter. I think the MS140 only weights about 7kg. My ML90 feels like it must be around 15kg.

MS140LS light weight for badminton and tennis.
We get quite a lot of inquiries for the MS140LS, for tennis and badminton.
Because the tension range of the MS140 is limited it is not possible to string badminton and tennis on the MS140.
The differences between both machines are:
- The springs are lighter for the badminton version, the tension range is 8-16 kg (18-34 lbs).
The tension range for the tennis machine is 12- 28 kg (28-62 lbs)
- The little weight (=hybrid system) raises both ranges by 4 kg (9 lbs)
- The tension scale for badminton is different.
- The clamping range of the racquet support is different. The Spindel is connected to the inner guiding arm on one side and to the outer on the other side.
