Do Prince Neos 1000 Clamps Wear out?

Curious if the clamps on the glide bars of a Prince Neos 1000 machine ever wear out? I'm getting a loss of tension and have checked to make sure my tension head is calibrated. I've cleaned the clamps with rubbing alcohol thoroughly. I've also adjusted my clamps to the point where they are even barely crushing the string and I'm still getting some unusual loss in tension. Is there some texture or coating that comes on the clamp that gets smoothed out over time where the clamp needs to be replaced?

Indeed they do wear out. I replaced mine after about ten years. I think TM charged me $75 for 2.
The glide bar is made of steel and the clamps aluminum. This is by design as the softer clamp “yields” to the bar which allows it to gain traction and not slip. Over time, the edges of the clamps smooth or round and they tend to slip.

Thanks for the info. I think the feet of the glide bars are tight but they are still a bit loose in the track. Could it be that the track is worn out?

Don't sweat it. I try to forget my HS and early daze in College. Definitely do not remember the info I have posted in this forum. [Someone is grinning and says "You have many Senior Moments" and other rude ageist comments.]

Wait, I take it all back! I went to the top and read down....you inserted the old thread into this new thread after my post! I did not have a senior moment (this time). The clamps do wear out.....

Vindication is mine!

OK, now you all have peaked my interest. I get more than 1/4" drawback, sometimes more, on some syn guts on my NEOS 1000. Is this normal? I have cleaned, adjusted the feet, and lubed the feet and rail slots. I realize the difference between CP and a lockout. I have nearly zero up and down movement of the feet in the rails but I have, regardless of adjustment a bit back and forth between feet and rail slots. I keep the glide bars and glide bar clamps or the string clamps clean and dry.

@graycrait how old are your clamps? It may be time for new ones. You can buy then individually. You could try one... I think they’re about $37 each

@Rabbit , even though I purchased this used through Tm only about 5 yrs ago, who knows how old the rail bars and/or clamps are. Who knows how old the cast table/rail slots are? But if you have over size feet then you can eliminate all side to side movement. To eliminate unwarranted drawback you need a narrow clamp track v rail diameter plus little side to side movement.

I suspect the cast table rails slots might be worn to a level that does not allow elimination of most of the the side to side movement. What I think I need are glide bar feet that are larger than OEM to make up for the loss of material in the rail slots over time. Or I need a new NEOS 1000 "table" that has fresh glide bar rails.

Where do you buy them for 37 each? I think I also have the same problem as graycrait, the slots that the feet sit in may have been worn out so the feet aren't tight in the slots anymore.

@CosmosMpower I got mine from TennisMachines.

And my bad, my remembrance was $75.....but it turns out after a quick check at TM, that was for one. You'd pay $79/each now. But that is still relatively cheap.

The rail is made out of stainless steel, so I don't think it'd wear out.

I was hoping it was 75 for 2, 79 each isn't that cheap considering I bought the machine used for about half price. Even though the rail is steel I think the feet are also. How do you adjust the feet to tighten them down, just turn the bolts on the feet? I checked and mine are all tight as can be.

This is an old thread on making those adjustments. OP's issue was the bars were too tight. Yours are perhaps too loose. @Rabbit contributed to the discussion though he may not remember it. I would try this before contacting TM.

Check out the thread in @esgee48 's post. I had explained it in there. The rails can get out of alignment, but that really shouldn't have anything to do with clamps moving after tension is released. If you're looking to adjust the rails, the bottom bolts aren't the ticket IIRC.

What makes you think you are getting a loss in tension?
Racquet tune readings. My string and string factor is always the same and my tension head settings are the same and the calibration is still accurate. The reading coming off the stringer is 3-4 pounds lower than normal using the same frame, string, string factor and tension.

Aaaa @10shoe, the problem appears to be at the other end of the clamp, either in the glide bars or where they rest on the table? :cool: OP is not complaining about the string slipping thru the clamp teeth.

I disagree @esgee48 . OP is complaining of tension loss and asks the following:
I would agree, but there are 2 areas where the clamps wear out. There is the string to clamp area and the clamp to glide bar area. The clamp could be slipping on the glide bar because of wear or the string could be slipping in the clamp.

BUT we’re talking about a lockout machine here and tension loss can come from changes in operation also.

I'm trying to address the loss of tension from all possible angles. My original thought was perhaps the clamps wore out due to loss in texture/coating. I did also notice that the feet for the glide bars aren't 100% tight in the table rails that they slide in. Would obviously like to address any and all areas that might be causing a loss in tension.

I am a bit mystified at the OP's issue. Absent some technique issue (which I cannot fathom), tension loss would typically because of string slippage in the clamp--with a Neos if the glidebars are clean and both ends of the clamps are clean (i.e., the string gripping end and the bar gripping end), the string should not slip (unless the clamp has truly worn out (I've probably got over 13-15k string jobs so far out of my Neos clamps, without a problem). Neos clamps have no real texture. @10shoe already showed how to see if that is happening. OP indicated that the machine was properly calibrated which itself seems to deflect clamp slippage (the calibrator is held in a clamp on one end--did it not slip?). I might make sure the tension head is really clean and double check the calibration. The other thing could be excessive drawback, I guess (maybe it doesn't fully even out) but that should be readily observable. I also think it's unlikely it is cause by the feet in the rails--there should be some play there anyway. If all else fails, call TM and see if they have a better diagnosis. Good luck.

Hrmm, I haven't checked that the end of the clamp gripping the glide bar is tight so I'll do that. What's the adjustment mechanism to make sure the clamp is tight to the bar on that end? I'd guess my machine has nowhere near 13K string jobs. I thoroughly cleaned the clamps and tension head with an old cotton t shirt strip and rubbing alcohol. There is some drawback but in my opinion it's not excessive.

What I meant by the feet not being tight in the rail is that when I clamp the string and release the tension head, there is some slack that is taken up as the feet shift in the channel and finally lock.

Same adjustment as that for the clamp. Look inside the base of the clamp where it grips the rail and you will see the rectangular points where the clamp grips the bar. Make sure the bar and the pads inside the clamp are clean.

Quick update, it was the adjustment in the feet of the glide bars. I found out because I accidentally dropped a glide bar on the floor and it bent in one of the feet a bit so I couldn't get it into the rails. I loosened the allen keys on both feet, adjusted them and tightened down. Now the feet are much tighter into the channel than before. I don't think the issue was the clamps afterall.
