Xpider Down Pressed Clamp Base

Good day stringers,
Recently I received new down pressed clamp bases from Xpider Co.,Ltd. Whole set consists
of 2 clamps, 2 bases with rails. My stringing
machine is Tourna 300-CS. I changed crank
mechanism on Wise 2086 electronic tension
head and installed new clamps set. This up-
grading works very well. New clamp bases really increase speed and comfort of stringing
process. Bases moving is easy and smooth.
Fixation of bases by palm is comfort. There are 3 ways for release of bases: clamp drop,
releasing button pressing, lever lift by fingers.
Xpider video is available on YouTube.

Product: down pressed clamp base.
Regards
Vladimir Kalmykov

Thanks for sharing, Vladimir!

I also have a 300-CS. How long did it take you to swap out the original base clamps and install these new ones and was it an easy process?

Had a look at the video and the base action is very nice...the lock/un-lock mechanism looks fast and easy. I especially like how the base lock releases when the clamp drops down. For those interested, video on YouTube is here:


Again, thanks for sharing!

Would you be willing to share how much they cost? Were the rails straight, or curved as in the video? I'm also curious about dimensions... but that might be an ask too far!

Took the words out of my mouth. I’m wondering if these would fit an Alpha Axis Pro...

I've sent an inquiry out to Xpider to get pricing and purchasing info. Will also try Tourna support to see if they can order...AFAIK, Xpider does not have a US distributor.

Will post back if I hear anything...

I’ve also messaged them and then messaged the UK Supplier who I’m still waiting for a reply from
Very interested in the outcome, as I'm also in the UK. You either have contacts or better googling skills than me to have found a UK supplier!

More like they told me haha! He doesn’t have the bases I. Stock as they’re super expensive. Has clamps. If you message me your email I can pass the details across.

Looks cool. But looks expensive, too. I'll be much more interested if the price is around $100.
I'm thinking a set of them would probably be in the $300-$400 as the replacement lever-locking clamp bases for my machine (which Xpider makes for Tourna) would be about $200-$250 for a set. I will post what I learn once I get in touch with Xpider or the distributor.

With @MattCrosby 's intel, I called the UK supplier. He doesn't stock the base clamps because they'd be £350 a pair, which he thinks is crazy money. The conversation continued 'I've told them maybe £250, but even then...'. I did buy a pair of string clamps off him, and will write a review of those after dinner. Probably in another thread, because they're deserving of some attention.

I was curious about our OP's motive to create an account, make this thread and then abandon us, so did a little googling. He also posted in a badminton forum, and provided two further responses there. Apparently one of them contained a price before being edited: the claim is that he said $510 for the full set of base clamps, string clamps and rails.

@Dags - Thanks for the info, Dags! $510 for the bases, string clamps and rails...steep, but I can see that price if you need to buy the string clamps and rails as well. Like you mentioned earlier, wonder if they have straight and curved rail sets available? I'm hoping since Xpider makes my machine, I'll be able to use these with no issues...

Just as an afterthought - that £350 figure for the bases would include VAT @ 20%. The $510... who knows.

It’s a pretty good deal. Not that I’m getting it right now but it’s good to know. I use my coarse made Eagnas for a while.
I can vouch for the clamps. Really nice. Didn’t spring for new bases, as mine appear to have some life left.

What machine do you have? Depending, not necessarily a given that the clamps and/or bases are interchangeable between brands.

Mine is Smart 909. It’s not much different from other models. The thickness of the rails could be a little unmatched for those bases. I can change rails all together of course while they are one of the concerns, too.

Hello all!

I just received an email from Ms. Wedny Chu at Xpider who confirmed that Tourna/Unique Sports should be able to order these clamp bases for us in the US. I have emailed Tourna and will update with pricing and ordering info once I hear back from them.

According to Ms. Chu, Xpider has a lot of demand for these clamp bases, with many owners of the Tourna 300-CS/Xpider Pro 690 having already purchased the base clamp kits.

Just heard back from Mike from Tourna: They can order these base clamps from Xpider and that they are priced at $400 for the pair. They do not have them in yet as a stock product, but are ordering some sets to test on 300-CS and 600-ES machines. He also confirmed that these bases and their clamps now come as standard equipment on the Tourna 800-ES machine and that they are "quite nice".

Edited for clarification...

Unless all drawback has been removed gravity release clamp bases are a bad idea.
These clamp bases can be released three different ways: lifting up at the bottom end of the locking-lever, pressing down on the top end of the locking-lever or allowing the string clamp to release the base clamp when it lowers into the base clamp.

Aside from the actual mechanism of how this base clamp locks and releases, how is it less secure than the rotating lock usually found? Don’t I still only release the clamp once tension is applied and the other string clamp is secure?

Asking for clarification...Thanks!

You should always clamp the string first then lock the base without preloading the base so the tension is equal on both sides of the clamp, then you should be able to release tension on one side. So now after you weave the next string tension should the equal again on both sides of the clamp before you release the clamp so the string does not slip through the clamp. The only way to know for sure the pressure has equalized is to release the base first then the clamp. Especially with a LO machine the tension on the previously tensioned string could be a lot lower depending on how the machine is used, and maintained.

@Arvin_C, this is pure speculation on @Irvin's part. He's never used gravity release clamps and doesn't have them; therefore they are not desirable. I can tell you first hand that they are a boon to stringing as far as I'm concerned. They facilitate less movement on the stringer's part, work great and are in no way detrimental to the string. I have used mine on all types of string including natural gut. If they were such a bad idea, why are they now standard on all upper level machines? @Richard Parnell uses them on his Wilson Baiardo in the video where he demonstrates an ATW pattern. They are a great option on any machine, including lock outs.

@Rabbit - Yes, was wondering if I just didn’t understand Irvin. I, myself, do not have experience with gravity-release bases, however I do know that Baiardo’s, Yonex Precision’s, Babolat Sensor/Racquet Station’s etc. all feature them as standard equipment. Figured with my intention to customize my machine to “pro” levels, might as well go all the way and get these along with the Wise...

Thanks!

Those types of machines are not lockout machines. When clamping, clamp the string first then lock the base. When you release the clamp, release the base first then the clamp.

Your "analysis" of lock out machines is pure speculation, and reasoning with faulty logic. Lockout machines would work perfectly with gravity release clamps. I can probably cite you 10 different things you've railed against that now you think are great.

It'd be pretty dadgum difficult to lock the base and then clamp the string. Yeah, I'd release the base first if I didn't have gravity clamps. But since I have gravity clamps, I release the clamp first and it handles releasing the base. It all depends on the tool set you have available.
