View Full Version : Problems stringing Natural Gut

Since I bought my stringer last October (Eagnas Combo 710, a dropweight with fixed clamps and 6 point mount), Ive mostly strung my racquest with Natural Gut mains and Isospeed Pro Classic crosses.

For the most part Ive had no issues and Ive used the following varietys of Gut with no problems:

Pacific Toughgut
Pacific Classic
Pacific Imperial (my favorite, too bad it's discontinued)
Global Gut (17 gauge in black)

I use the KProOpen racquet which has main tieoffs at 6B, and cross tieoffs at 5T and 12B (which is the 3rd cross from the bottom).

This weekend I reluctantly decided to cut out my last Imperial Gut setup which had been strung in late April because I had a indoor match coming up and I always have issues with my serve going long when I have a old setup in a indoor match in the middle of the summer.

I only had 3 half sets left:

Pacific Primegut (I have yet to get this to work, although the first time was with no grommets, it does seem very sensative though)

Pacific Classic

Global Gut

I started stringing the Primegut. I did the mains and tied them off with what I thought was no issues.

Then I did the Isospeed crosses from the top, got all the way to the bottom and clamped the last cross (which goes over where one of the main tieoffs are).

Then when I tightened the knot for the cross, I heard a "CRACK", and then seconds later the main in 6B snapped right at the main tieoff.

I proceeded to string the Classic and something similar happened again. This time I heard a "CRACK" when tying off the last cross, but only a couple strands of the main broke off. It seemed more like it was scored right where the fixed clamp intercected it then necessarily on the main knot.

I took it off the machine and about 10 minutes later the main snapped.

Which leads me to wonder:

1) Was this gut maybe of poorer quality?

2) Did I pull the knots too tight and weaken them. I did use my hand but I did also pull them tight enough to try to pull all the slack string thru. Maybe I would be better off just securing the knot and letting that slack string tighten up when I remove the clamp? The weird thing is the other main string at 6B doesnt break though, just the one on the same side as the cross tieoff.

3) Is my fix clamp drawing back and cutting thru the mains somehow? It seems hard to avoid drawback on the last cross.

I went to the Global Gut the next day and it worked just fine. But this time rather then pull really tight to cinch the knots for the mains I just pulled tight enough so it was secure around the string and I let the slack tighten up on it's own when I released the clamp. (which actually is more like I did most of the other jobs, it's a new phenomenon where I pull extra tight)

Any ideas?

It's tough to visualize your situation but sometimes the grommet has the sharp edges that may be cutting into your gut. So check the edges and make sure.

It is highly unlikely that you had two separate batches in poor quality.

Check the usual suspects.

* Grommets for cracks or unusually sharp turns or ends.

* Clamps -- too tight and crushing the string?

* Gripper -- Does it make the string bend at a very sharp angle? My previous dropweight had a linear gripper that was wreaking havoc on strings.

* Pull speed -- Do you let the dropweight down very gently?

Probably following would help:
1.Were packages sealed?
2.What were tensions/gauges?

What was your rationale to put a gut in mains instead of crosses?

1. They were half sets in zip lock bags

2. They were all 17 gauge. Ive done 17 gauge before.

3. I dont really need a rational, I like it that way. I like my setup to feel mostly like Gut, not like something else....

Ive been playing with something like this setup for 3 years, and I used full Gut before that.

I like Pacific Gut a lot, but I have to admit, I've had problems with it in the past. I think at any given gauge, it's thinner than Klip (the other gut I use a lot of). As for Global, I've never used it, so really can't comment a lot, but I've read that it's thick (at a given gauge). Gut is more sensitive around the knots. I use a type of "deadman's" knot for gut. Plus, I don't use a starting knot any more. I go back and tie it off like the rest of the knots.

Thanks.

I dont use a starting knot either, I use a starting clamp.

So do you think it's okay to just pull hard enough to make sure the knot is formed but leave some slack between the knot and the fixed clamp?

After this it seems safer then pulling tighter to get rid of that slack string.

It seems like when you release the fixed clamp that slack string goes away probably because the lack of tension spreads out onto that last main or cross.

And also, I really like Pacific string as well. Ive had no luck however with Prime, it's most expensive kind. (0 for 4)

I am going to try the "new" Klip Legend Tour that is black and see how I like that. I used regular old Klip Legend in a full job of both 16 and 17 gauge before but I didnt like it. (mostly because back then I mostly used a full job of Wilson Natural Gut and there are worlds of difference between those strings)

My Gaucho Gut came in ziplock bags :shock:. It snapped 3 times in a row for me while stringing crosses

I didnt buy them in ziplock bags.

I strung half of a full set that was in a sealed package, and then I put the other half in the sealed package and put that in a ziplock bag. And then I put the ziplock bag in my closet where it suffers the least amount of tempature varience.

Ive done this with tons of sets of gut over the years and havent had a problem with it.

clever sir

But I know what you mean. If I bought them from anyone else and they were in ziplock bags, I would be ****ed. There no reason to buy them that way. (not when it's super cheap for a full set of it that is sealed)

Yea I'm probably never going to use or string cheap gut anymore

try the babolat tonic 15 for the mains. All the feeling and quality of bab gut, very durable, and less than the vs. I've never had it break when tying off any knots and it lasts a long time. I hybrid it with gamma zo twist 16 in the crosses and it works great. Also works well with bab rpm blast

Strange, never heard of that before-- sure you got it from the manufacturer?




OP:

I'm sorry to hear so much gut go to waste :( I would check the gripper and the grommets-- usually the two main suspects. If not, I suppose you'll have to tie off a touch looser on your last pulls or up the tension 3-5 lbs to compensate for the slack.

Best of luck
