Looks like a really well built machine, never heard of that brand before tbh.

Are you stringing badminton rackets on that machine as well? The main towers appear to be very far apart.

It is from an Italien company, i would say they are using Parts from the same OEM as Gamma. This particular Maschine costs ca. 4000 Euro, cheaper as the Gamma 8900 or 9900. I string mostly only Tennis Rackets

I built my own. I've been using it for about a year and a half and have strung a couple dozen rackets with it.

Curious to see how it works !

It works quite well, actually. It pulls slower than a commercial machine and the clamps aren't quite as convenient, but for a couple hundred dollars in electronics, hardware, wood, and 3D printer filament, I'm very happy with the results. I string my rackets and for the group I play with. It's a hobby, not a commercial endeavor, so it gets the job done. And I like the convenience of being able to try different strings and tensions with different rackets on a whim.

But that doesn't mean I'm not looking for a good price on a good used stringing machine!

I told you how well it works, but I didn't tell you HOW it works.

Basically, it's an Arduino single-board computer connected to a stepper motor controller and the guts from an electronic luggage scale. I set the pull weight when I turn it on (in 0.5 pound increments), wrap the string around the clamp, and push the button. The stepper motor turns a threaded rod which pulls the clamp assembly. It pulls at three different speeds depending on how close the measured tension is to the desired tension, slowing as it gets closer. Then it holds at that tension until I clamp the string and press the release button.

I initially calibrated it using free weights, so it's quite accurate.

Could you post a video/clip of you mounting and pulling tension on it please? Also very curious to see it in action!

Someone posted a 3D printed one a while back - looks like yours is similar or based on the same project

KhordUino (badminton stringing machine)

Stringing machines usually comprises of a sturdy metal frame, clamps to hold strings in place and a tensioning system to tighten strings. Electronic models have control panels for precision stringing but do cost a lot more. The KhordUino design is quite different from most metal frame stringing...

Looks like a neat project for sure

You can also get parts CNC out of metal using a service is PCBway if you want something more durable

Yes, mine is based on this project, though I have made a number of customizations and have modified the code to some extent.

I've looked into getting the spreaders machined, but it's pretty expensive for just two of them. However, I just backed a desktop-sized CNC on Kickstarter, and I'm going to see if I can make them myself when it arrives. Those are the only parts I've broken, so I've printed a bunch of spares. Fortunately, even if one breaks, I can finish stringing the racket before having to replacing it.

I may try to design and machine some improved clamps as well. They don't break, but there is definitely room for improvement with aluminum.

忘了说了，它还附赠了Toyozouki的男士羽毛球夹！！太棒了！！！

我偶然看到了您关于GOSEŃ GM1300的帖子，想问问您是否有这台机器的使用说明书？能否提供图片版？谢谢！

Other than the clamps, made from whatever I could find in my garage.

How is the strength to counteract the mains?

If you can see from the second image I used chopsticks to brace the posts from moving toward the center. This was all an experiment to see if I could come up with a way to string my Wilson Zephyr from the 60's. It evolved from there but tension is too low for modern rackets. I'm using a Klippermate these days.

i have couple ppl from my club that did hand stringing for those rackets and still can do it if i ever need one strung - but yes, the tension would be very low compared to doing it on a machine

So I did a thing...

Since I haven't been tweaking my StringMaster Deluxe for an unsual amount of time now, it started itching again a couple of months ago.

Reason:
The string constantly got caught at this corner which started driving me nuts, so I thought, why not add a 3D printed plate or something to fill the corner?


But why not using the addidional space for an extra tooltray? And with the sensational support of fellow BC member @Mr Arc2 who made the basic 3D construction and a clubmate who printed the thing, I ended up with V1.0 (PLA):




Didn't like the color (obviously), but the rest turned out to work as expected. So with a bunch of minor changes and myself ending up buying a 3D printer myself (of course... ), please meet V2.0 (PETG-CF). And I also added a printed inlay (TPU):





Again, the design changes were working as expected, the only thing still bothering me were the small pieces of scrap string to unblock blocked grommets that kept tangling up and always getting in the way somehow.

And behold, V3.0:



Strung a couple of rackets now with this version and so far, I am 100% happy with that solution. Handling the scrap string pieces now is so much easier and I really enjoy the extra tool space.

Never stop tweaking!

I also need something for the other side to cover the break lever which I don't want to remove because it's a pain to put it back if needed

someone needs to make string scrap replicas out of silicone.
