Hey guys,

We have a Prince NEOS 1500 and it is leaving marks on the strings. I have not figured out how to recalibrate the tension head and wanted to show you guys pictures to see if you had any suggestions.

Fold a business card or cut down the paper string packaging to fit into the gripper head.

I am not sure how your string is getting damaged and I can't see any damage in the picture. There are basically two ways the string could be damaged. Either by the gripper or by the clamps. First make sure they are both clean as a string slipping through either will cause damage. Then make sure they are adjusted properly. If either is too loose the string slips through if they are too tight they mash the string.

I have the same marks happening on my Neos 1000. They are from the tension head.

I know this is a proven work-around. But it is just ludicrous that any professional machine should require this.

^^^ I did not start doing it until recently, and I do notice that the hard polys don't get marred when using this card. The other alternative is to sand down the gripper surface but that kinda defeats the purpose. I would first try to adjust the gripper space adjustment, before using the card.

That is correct, they are from the Tension head not the clamps. I have tried adjusting the head, nothing works...

I will try the business card method and report back...

^^ Yeah, it's pretty redicilous that a proffessional machine such as the Neos requires the use of a business card.

The Neos should not require a business card. Sounds like the machine is not clean or adjusted properly. I recommend cleaning the tension head gripper throughly with denatured alcohol (I use a cotton shoelace and a long bristled toothbrush--use the soaked shoelace to get a good bit of alcohol into the gripper, let sit a minute or so, scrub with the toothbrush and buff with the soaked shoelace, repeat, and then dry with a dry shoelace). Then, the tension head can be adjusted utilizing the tension head screw--counterclockwise to tighten and clockwise to loosen. It should be adjusted so that the string is held without being crushed (some softer strings may get slight ghosting but a good stringer who knows what they are doing can minimize that as well). Many of today's strings are coated with all sorts of materials that leave residue on the machine--you should clean the clamps, the glidebars (if applicable) and the tension head pretty often.

I agree. When I went back to gut, I noticed some discoloration of the string where the tension head gripped it. I adjusted the tension head gripper and problem solved, the gut was pristine.

As one poster said, the Neos 1000 does the same thing. The Neos 1500 and 1000 use the same tension head. I have a Neos 1000 and it leaves slight waffle marks on my string after each pull.

Although it does leave a slight mark, it's not damaging the string unless you're gripping them too tight. I have mine set at the lowest grip strength without slippage.

If it's really bothering you there are 3 ways to fix the problem

1. Use a folded business card in the tension head. This will eliminate the problem but will cause you to string slower. Also the business card needs to be replaced every 4-5 string jobs.
2. Send the entire string machine to Tennis Machines. They will sand off the coarse grip surface of the tension head. Usually at no cost. This a hassle because you need to package the whole thing and you also need to wait to get your machine back.
3. Sand the waffle pattern on the tension head yourself. This is not recommended because if you create an uneven surface you wil need to replace the tension head clamps.

what is the process of sanding exactly?

Maybe sanding wasn't the exact term I should've used.
More like filing off...

I don't know the exact process but Tennis Machines told me it will be done so the tension head clamps are even and parallel.

If you want to do it yourself you can either
1. take apart the tension head and file it off
2. Stick a nail file in between the clamps and file it off.

The difficult part is that you need to file off the coasesness and keep the clamps even.

I really DO NOT recommend you doing this yourself. After all you paid a lot of money for the machine. It would be a shame to ruin it just because the clamps leave slight marks.

After I got home, I looked at the pictures. I agree this isn't damage and really shouldn't be anything to worry about.

With regard to filing the tension head, I would very much argue against that. I would imagine there is a reason Prince added the feature to the gripper. One would imagine that long ago, the gripper was smooth. The waffle pattern must have been added to correct a defect or enhance the tension head's effectiveness.

Again, I don't see any damage to the string, certainly nothing that would shorten its life. When I used the delivered lockout head, I had adjusted the string gripper to its loosest setting and had no trouble with slippage.
