anyone tried these?
they are said to be just like the Babolat sensor clamps but are they?
or can anyone find a clamp that is really close to this that is good? but not the actual Babolat clamp
I have an Eagnas crank stringer that had the PN-1006 clamps that needed to be replaced. I bought the PN-1012s, and they are a big upgrade, but I can't speak to how they are compared to Babolat's. I'd guess not in the same ballpark, but they do the job for me.
And by looking at them they look like they fit universal clamp bases as well. is this true?
Meant to say do these clamps fit universal clamp bases?
i had them on my combo 910.
i broke one. The bolt used with the thumbscrew adjustment
sheared off of the lever assembly (IIRC).
It was out of warranty and i bought another. I've since sold the machine but other than breaking one, They worked well for me.
I'm not sure there is a "universal clamp base"?
If it's a lilly-lee machine, they should fit fine.
What's a lilly-lee machine? picture?
This is the shape of my clamp base(same as a lot of machines)
oops sorry picture didnt work
There is really no universal clamp base. Some may look the same, but different diameter. From previous posters here it was mentioned that Alpha and egnas were different size they look similar but are different, so do not go by looks , you need measurements. One person with the Alpha had to have a machinist alter the clamp to work, so it would not make it cost effective to machine an Eagnas clamp to fit if it is a different size.
I have a Pro Master machine now sold by xtremesportsmachines and that one was same size as the Babolat star 4 and the star 4 fit the eagnas so I knew that Eagnas would fit mine.
That said the eagnas is not that great of a clamp compared to the ones that came with my machine, I just keep the eagnas ones as back up in case something happens to my originals.The eagnas ones have some drawback where the orig. are rock solid. I also like the 5 tooth clamps over the 3 tooth.
Back to your question, there really is no universal base.
You could call Eagnas and let them know your machine and ask, but after viewing their web site I would hate to think of the response you would get.
I have these clamps on my Eagnas Flex 940. I like the clamps and have never had a problem with them. I string a lot with poly (Cyclone) and haven't had slipping problems.
I do not like the cone lock bases on this machine, tho, and plot ways to replace them.
Ok thanks guys. ill get to my point now. will these clamps fit in the same bases of a RAB stringmaster or a Pro's pro base?(both same shape, I cant post picture so if you want please have a look on the internet) or those kinda shapes
to me they look exactly the same as the ones on the Eagnas machines.
likely so, i think pro's pro and eagnas are both made by lily lee.
The Eagnas PN-1012 clamp is decent. The clamp is about 12 mm (about 1/2 inch) wide. If the base has an opening that wide then you are good to go.
Do not go by just looks, as some are different. You really need measurements, or verification by someone who used these clamps in a machine same as yours to be sure, otherwise you get responses like they should or likely so .
Like I said earlier, a poster here a while back purchased these Eagnas clamps and they did not fit the Alpha machine , but they still looked the same, and those had to be machined to fit.
Few years ago we installed 2 on a machine where the Pn-1012 clamps were larger than the base clamp sockets. Just grinded them down a little and they fit fine. Took about 5 minutes. Original replacement clamps for the machine were twice as much.
I used these clamps for about 12 years now and have had zero problems. Wish they were self cleaning, but hold tennis very well.
While this may be true, unless you grind it to exact specifications you can get slop, which can turn to drawback. If you do not grind them both exactly identical you will have one with more drawback than the other which can give inconsistent stringing, and consistency is what stringers strive for.
To the OP:
Why not get the proper size needed and do the proper job?
What Jim is talking about is the post diameter. Each manufacturer seems to have different post diameters, so their clamps don't fit other manufacturer's bases. They looked good to me too. I'm the one that had posts machined to fit my Alpha. They were good for about 40 string jobs, then they began to slip, no matter how good I cleaned them (except on polys). I still use 1 of them on polys. It has a very smooth action. The other one isn't smooth at all. I rarely use it. I do like the design though. Maybe it's just the metal isn't hard enough. Polys do tend to wear grooves in your clamps over time. Some of the old Alpha clamps are really good, but I'm not convinced the newer ones are.
Find and read the threads on replacing parts in the cone lock bases. People seem to be happier after "upgrading" those bases with new parts. Makes me happy I have the Eagnas Combo 710 with the spring-assisted clamp bases.
