    That's the one, I think it's the same system as the Star 3

    That's the one, I think the Star 4 calibration is the same.

    Just wondering, what is the brake function on the keypad used for?

    Me too, I would really like to know if the brake function electronically turns on by the press of that button or even automatically brakes the turntable when you start tensioning?

    The button does not brake the turntable.
    There is no electronic brake for it on this machine.
    Unfortunately I am clueless what the button is used for.
    Maybe the device could work with an electronic brake machine and the button is just preinstalled for that case?

    After stringing happily for quiet a while now, I came to really like the self centering tower system.
    However there always have been the idea in the back of my head, that I would like the top and bottom support to be separately adjustable in a more convenient way.

    With all the lockdowns going on I figured it was finally time fore some modding.:cool:

    Lets cut right to the chase, here is the before and after.

    Before:
    1 adjustment wheel for side support
    2 adjustment wheel for tower distance
    3 hole with a hex screw in it

    To adjust the top and bottom support, I had to take an Allen key, put it in the hole, unscrew the support, move it in position, tighten the screw again and put the Allen key away.

    It was good enough to work but not very precise and limited in range.
    Also the support was able to turn, so I had to double check if it was upright before fastening the screw again.

    After
    1 and 2 same as above

    3 new adjustment wheel/knob for the top/bottom support

    Now I got far more range to work with, along with better precision.
    And all it takes to adjust it, is a little twist on the wheel/knob.
    All in All it is a little rough around the edges but I already strung my first racket with that setup and it worked really well. So totally worth it for me.

    Here is a short overview how i did it.

    pic 1 - some parts that i used

    pic 2 - modified support arm:
    - drilled a hole in the arm
    - put a thread insert at the end (metrical fine thread with a pitch of 1 mm)
    - made one side completely flat

    pic 3 - new parts
    - put a knob at the end of a thread rod (same size as thread insert of the arm)
    - made a connection part that prevents the rod from getting pulled in or out

    pic 4 - all parts together

    pic 5 - inlay for the tower
    - the little bolt sits where the hex screw was and holds the plate inside of the hole for the support arm.
    -the plate aligns with the flat side of the support, preventing it from turning


    Biggest challenge was, that the wheel for the side supports partially covers the hole of the main supports.
    Unfortunately those wheels are extremely tight (probably glued in) so that I was afraid that I couldn’t remove them without damage.
    I found a way to work around it but that involved some non centric drilling which was more complicated because I didn't had the popper machines for it.
    Still worked out in the end so whatever...


    I may have gotten some technical terms wrong here and I apologise in advance if my descriptions are to confusing, but I hope you get the idea...

    Does the machine come with two different sets of 6/12 arm supports? (two shorter arms for tennis, and two longer ones for badminton) Or did you somehow modify yours to be longer, than the ones you see on the official pictures on Pro's-pro's website?

    It comes with 2 pairs of supports. Long for badminton and short for tennis.

    I'm sure the Star 3 had a high/low screw pair - you'd get one right and it would nudge the other one.
    Cue fifteen minutes of seesawing.

    Yes it did.. nightmare when i thought it was a good idea to do 2 full turns on one. Then i had to do a reset with 22 turns and 11 the opposite way as the numbers were massively off lol.

    According to the manual:
    Brake: Control the turntable rotation or stop.

    Yes, I've seen that in the manual but it does not seem to do anything.

    I guess it doesn't do anything because this one is not equipped with an electronic turntable what so ever... Perhaps a future 2.0 version...???

    4 years and 100+ Stringjobs later it's time for an update.

    The machine is still working well but I did make some adjustments here and there.

    Clamp base problem
    About an year ago one base started to trouble me. Sometimes when I tried to lock it the lever would snap right back and unlock the base. This worsened over time and really annoyed me but at first I couldn't figure out the reason.
    I tried to adjust the base but it didn't help so I started to disassemble it.
    The way the locking mechanism works is pretty simple. On the bottom of the leaver there is a little notch (red arrow) and underneath the lever is a spring loaded pin (yellow arrow) that shoots up when the lever is pushed. The pin holds the lever in the locked position until you push down the pin by dropping the clamp or pushing the release button.
    Imagepipe_95.jpg
    Upon closer inspection I found out that the edge of the notch was uneven and rounded of. If the pin went up all the way or still locked the lever but if the pin got stuck even a tiny bit it would slip off and release the lever.
    A little bit of grinding with a Dremel and the edge was sharp again. After that the base locks reliable again.
    Upgraded clamps
    About 2 years ago I replaced the clamps with these
    Imagepipe_97.jpg
    The new clamps are slimmer and fit better between the Badminton strings.
    Also they don't need those diamond dusted inlays like the original.
    Not a much needed upgrade but a nice improvement in quality and feel for sure.
    The clamps were a little too long for the machine so I had to cut the shaft by about 1cm.​

    Upgraded side support
    Just recently I bought these
    Imagepipe_98.jpg
    This is a huge improvement!
    The original supports are bulky and would even get in the way of the clamps from time to time.
    The new supports are much smaller and so much more pleasant to work around. They grab on the frame really nice and won't allow for any unwanted movement while still protecting the paint of the racket.
    If you only string badminton rackets I highly recommend them.
    However, I recently had a chat with @baddynerd who send me this picture.
    Imagepipe_105.jpg
    It looks like the tomcat nowadays comes with new side supports. The new silver pieces seem to be less bulky and probably fit better for Badminton then what I got with my machine.
    Maybe we can even get them as spare parts?
    That would mean there is less need for an upgrade but I still really enjoy my new side supports.
    Shrinking tube on the side support arms
    for better grip and looks...

    Did you ever wonder what the inside of the tension head looks like?
