**Stringway – information – Questions – answers**

Is the MS200 still available? Would it be possible to order it through new tech tennis?
I am sorry to tell that it is not likely that we will produce the MS200 again.

There is not enough interest from the market to justify a production series.

The MS200 is in the same price range as a lot of electronic machines from China and stringers probably prefer these ☹.
 
I have the Stringway triple and double, and find them to be less accurate than the PS Claw 2.0, because the dial is looser and does lose the setting easier.

I think this is important to know for users of the Stringway flying clamps.

There is a “built in friction” which should avoid changing of the setting.
The friction is provided by a small piece of string in the aluminum pull rod.

If the adjustment knob turns too light just put a new piece of mono string in.

Can you give guidelines to "update" older clamps?

Or is this not possible...
 
Pretty frustrated with my ML100 right now. My racquets keep sliding from the throat mounts when I tension the crosses.

I started noticing this about a month ago and it’s gotten progressively worse. I’d say the center of the bridge will move up to a half an inch on each side as I tension the crosses. I strung a racquet today where the racquet began moving as I tensioned the 5th top cross. As I progress down the throat towards the last few crosses there’s more racquet movement.

Initially I thought I just needed to clean the points of contact where the mounts touch the racquet but it didn’t work. I’m concerned I’m damaging my racquets, because there’s a creaking noise that occurs when the racquet is moving as I tension the crosses.

I don’t have any issues when I string racquets that require the Babolat retainer, but I think that’s because the retainer locks the bridge into place. I’ve tried tightening the clamping hooks and experimenting with their positioning but haven’t had any consistent results.

I’ve been using my machine for 3 and 1/2 years now without issue. I’ve double checked the manual and online videos to make sure I’m not improperly mounting the racquet and I believe I’m doing everything correct. It’s a confusing problem because the mounting mechanism seems so simple, that it’s difficult to see what the point of failure could be.

Any thoughts/suggestions would be appreciated. I can post video if that would help. Thanks!

My racquets keep sliding from the throat mounts when I tension the crosses.
This happens (rarely) to me when stringing the last 3 crosses.

I understood this could happen when the "balance" between main- and cross-reftension is "off".

The main purpose of the frame-support on a Stringway, is to protect the frame against the force of the tension of the mains.
The crosses balances the mains. And when all crosses are done, you could lift the frame tension-free from the supports.
But when your first 10 crosses already "balance" the mains, then at that moment the frame is tension-less in the supports, and every next cross will pull it sideways.

Did you up your X's ref.tension?

Since I've owned the machine I've been stringing my racquets with the Ms and Xs at the same tension or doing hybrids where I might be stringing the Xs 2-3lbs lower than the mains. No changes in tension recently that would line up with the bridge sliding.

I know Stringway is big into promoting their tension advisor calculator but to be honest I've never really looked into using it. Perhaps a different X tension would minimize the sideways frame movement?

You can add the friction by just replacing either the alu pull rod or the hole eccentric set when you do not have a vise to push the cross pin in,

IT is of major importance that the (throat) supports keep in contact with the frame until all strings are tensioned.
This depends on the difference in tension in the mains and crosses.
That is the importance of the tension advisor.

I think that Mathieu R explained this very well.

You can also use the Babolat retainer which will limit the sliding.

STRINGLAB 2 ACCURACY
0scg8nj
Yesterday we got a question about the accuracy of the Stringlab 2 in relation to other string bed tests.
Hereby an explanation:
The answer in one line is simple: “Accuracy and reliability through simplicity”

HjhSzv.jpg


pnxdVDQJj

By switching the lever the system creates a certain deflection of the string bed.
The force transducer measures the force needed to create that deflection.
The system is calibrated to translate the test result into string bed stiffness.

The electronic system is the same simple system as in a digital scale.
The Stringlab can be recalibrated mechanically with a screw but that is never necessary because the electronic system does not shift at all.

If you have questions let me know.
 
When using the stringlab 2, it is possible to convert the dt value with an ERT300 disk ?????

The Stringlab 2 and the ERT both measure in kg/cm.
With the ERT they call it Dynamic Tension but it is both string bed stiffness (SBS)

So our table does the same as the ERT table only more accurate.

Someone tested the sbs on different systems shown in these results

There can be a difference in result as explained in this earlier message:

There is a principle difference between the RDC, Stringlab2 and the “vibration test”:
With the RDC and the Stringlab the string bed is deflected so the string has influence on the test result.
The ERT measures the “surface stiffness”.

Thanks for another detailed response. Please see my notes below:
Hello @BravoRed691
It is good to share issues because we can respond and advise then:

1) Clamping Hook Slippage? “
I assume this happens when stringing the crosses. Yes
It is not the intention of the “clamp down hooks” to prevent the racquet from slipping, They are “only” meant to keep the racquet behind the main supports. The racket at the throat can slip completely off the "clamp down hooks" requiring the racket to be completely restrung.
So do not overtighten them.
The racquet slips when there is not enough pressure between the racquet and the supports. This can happen when the tension on the crosses is too high so that the racquet head becomes longer and moves away from the supports. Does this mean there are some tensions that I will not be able achieve on certain rackets? I am stringing in the mid 50 lbs.

Adjust the racquet support so that there is minimum pressure between the frame and the supports and this should be the same after stringing.
Check if the racquet remains in contact with the supports while stringing the crosses if not lower the tension on the crosses. It indeed does not remain in contact with the throught side supports.

Do you use our Tension advisor to calculate the tensions? Not yet but i will consult it. Does this mean there are some tension that I will not be able to achieve on certain rackets? I am stringing in the mid 50 lbs range.

Are the friction pads still in good condition? My model has these rubber strips. Does it function the same as the friction pads?

2) Automatic Lock System:
Can you check if the lock still works well when you wait 10 seconds before you lower the lever after taking the string out. I did not see an significant difference after waiting 10 secs before lowering the lever after taking the string out.

If that works well the tension head “springs back” too slow and needs lubrication:
Add some grease on the pull rod where it passes through the U-shaped casting and under the nylon washer on the disc. I can still try this. Is there a type of grease that is recommended?

3) Tension Head Pin:
When the shaft of the tensioner moves out you only have to tighten the locking screw in the disc. This works! Though the locking screw will still work itself loose. Not a big issuge. Thanks!
pnY6Qt6Rj

Misc
1) I somehow lost one of the two, small, flanking/side pins, just under the clamping teeth.
We will be happy to send you some pins it is easy to insert them. Yes, please, i would be happy to pay for shipping to receive the proper part. I noticed this part is not shown in the manual under "Overhaul of a Stringway Clamp."

2) The Single Action clamps do not glide equally well on the guide rails/track.
Because this is only a shaft and a hole there is no reason that this changes in time by using it.
Take care that everything is clean and dry also the inside of the holes.
Polish the shafts with Scotch Brite this will improve the locking and moving around. There is a hex screw under/in the base of the clamping apparatus that goes over/around the glidebar that has come loose. Tightenin this helped a bit. There is still a difference in the ease of gliding between the two clamps but it has been improved and I think the difference is acceptable. And there is probably a range of tolerances to be expected when they machined the glide bar and the base of the clamps.

Hello @BravoRed691
I do not understand what this pictures shows / means.
Please explain
I was hoping to show how my tension head is having trouble locking well into the starting position. The "Disc S10" barely catches the locking bar. A couple of times, it missed the locking bar completely and the lever with the weight would crash down; hopefully no damage was caused. My walkaround has been to manually pull up or hold the locking bar's lever/handle on every single lowering of the bar after releasing the string from the gripper. I'm so used to doing this now that i dont think about it but i think it's costing me a few seconds on every string and it takes away from stringing experience.

I will try greasing the "pull rod where it passes through the U-shaped casting and under the nylon washer on the disc". Any other ideas and is there a grease that is recommended?

Tks!

Hola All!

How much play should the turntable have on the shaft? When stringing with some stretchy strings, the lever/bar will bottom out. Double pulling does not help to take up enough slack. I noticed that some of the extra slack is being pulled in the other direction by the turntable tilting away from the tensionhead. In this case, I need to manually title the turntable towards the tensionhead and I clamp and lower the lever/bar. My model does not have the Concord System yet it naturally tilts down and away from the tensionhead and wobbles as it turns. Just wondering how much wobble is normal; hard to quantify I know.

And what is the purpose white piece shown below. It was never installed when I got the machine, nor do i know how to install it properly.
I see it in pictures and videos so i assume it does in the round hole directly beneath it in the pic. Note: It doesn't affect the wobble of the turntable. And in the pics above, i simply slide it in the hole, it is not secured.

Hello @BravoRed691

This is a clear picture showing the clear problem.
In the good situation the height of the locking surface between the disc and the locking bar should be 5 to 6 mm.

In your case the locking bar does not move up far enough to reach that situation.

The reason for this is probably that the bolt which holds the release button is bent. This can happen on older machines when the string brakes and the weight drops down.
On newer machines there is an end stop which catches the tension head

These pictures shows how to bend the bolt back without change of braking:

@ BravoRed691

Check if the shaft is moving in the frame.
I will get back with you after dinner showing how to solve this it is easy:
On the non Concorde machine the shaft is fixed with the main screw and the nuts (mutter) 1 and 2.
If the shaft is not fixed well unscrew nut 3 a little.
Tighten nut 2 firmly.
Tighten nut 3 a little less tight.

Make sure the the half sliding bearing is pushed well into the frame.

The nylon bush on the screw is the table stop it prevents the table from hitting the tension unit

Thank you, Fred. I think I will need to try this solution again. After I tried to push the locking bar upwards like in the picture, it seems like the issue is / could be solved. The disc contacts the locking bar more. However, after the first pull, the issue returns with the disc catching the locking bar only a little. I also now notice that there is a "small bump" / protrusion on the curvature of the disc, perhaps inhibiting the disc from returning back into the locking position fully? Or maybe the bolt which holds the release bar is more damaged than originally expected? Either way, luckily, I can still manually manipulate the release knob to push raise / push the locking bar up towards the disc.

Thanks for this as well. The shaft appears to be fixed fairly securely. There is some movement/play back and forth but it's minimal and does not seem to be enough to allow the turntable to tilt / wobble as much as it currently is. Regardless, I adjusted mutter 2 and 3 and was able to secure the shaft even more firmly. The movement of the shaft was reduced even more.

What is the "half sliding bearing"? All nuts and bolts are secured well within the frame.

I've seen videos of this (or similar models) machine being used by others and my turntable certainly has a much greater degree of tilt and movement than the others. I'm thinking of packing the hole (with a sponge?) in the turntable which goes over the shaft to remove see if it make any difference.

I think there can only be 2 causes:
- The locking bar can not move up far enough to reach the 5 mm height of the locking surface because of the bent bold.
- The locking bar moves up too slow because of friction.

I do not think a small bumb on the disc will cause the problem.

I looked at your picture more closely and saw that you have 100 % sliding bearing between the shaft and frame.

About the clearance: How much does the turntable move up and down because of the clearance? Keep in mind that there is a huge lever action in this feeling. When the clearance in the bearings is only 0,1 mm it feels like a lot of movement at the end of the big casting.
 
ALL ML100's OUT OF STOCK (n)

pdPnfqFbj
We received quite some questions because we had to put all our table We received quite some questions because we had to put all our table top drop weight machines on “out of stock”.
The reason is simple:]
We no longer have any main frames in stock.
We miscalculated our sales last months and didn't think about the long holidays of our laser cutter.
It will take 3 to 5 weeks before we can ship again. ☹

Question for @Stringway Official and other stringers.

On my ML90, which I have had for 12+ years, I removed a bolt inside the base that limits the table from rotating 360 degrees. So my table can rotate 360 degrees. I did this many years ago when I first got my stringer.

Are there any downsides to this? I like the table being able to rotating 360 degrees and more in line with the direction the string is being pulled (for some parts of the racquet when stringing).

There are no downsides, on the frame that we use now you can slide the table stop away in the L slot.

But that is particularly meant for badminton stringers so that they can mount the racquet the other way around (what we advise)
65badmalt5klj

I don't know what you mean, but 360 degrees rotation is impossible on a Stringway (and I think on any dropweight)

I agree with MathieuR because the tensioner will be in the way. The handle of the racquet can not pass the tensioner without the Concorde System,

There is a fundamental reason for the tensioner being “in the way”:
We want to pull tension on all strings horizontally with minimum friction in the grommet.
