    Few months ago I thought that construction of stringing machine isnt’t complicated and should’t be very difficult to make it in home. I watched of photos and some stringing videos, spoke with stringers and of course read threads on BadmintonCentral. Then I drawed some project, collected pieces, and get down to work.
    Tension: 6-15KG (13-34LBS)drop weight- not level horizontal, but something like in StringWay/LaserFibre “constant pool”; tension is accurate on the every position of angle (it tested using fishing scale).
    8 point mounting head system (2 inside on the centre, 4 on “traditional” position, 2 on the top of frame)
    I restringed almost 40 badminton racquets (graphite, aluminium even steel) isometric and oval shape (f. e.:Cab 8200, Cab23, Iso 62, 63,75MF, MP 21, 23, 27, 55, 100; AT 300; Wilson Sting Power, Carlton Airblade 600) on the different tension (15-28LBS)using various guage of strings (0.68-0.80).
    Best time to restring one racquet: 33min (non Yonex racquet- large grommets)
    String lenght: 9m.
    String pattern: 22/22, 4 knots (3 Parnell knots, 1 starting knot)
    About my stringing job from picture:
    racquet- Yonex Ti-5
    string- Pro’S Pro Explosion 0.69
    tension-Main: 10KG (22LBS), Cross 11KG (24LBS)
    What is your opinion about this badminton “machine”? Would you risk to give me Your own racquet to restring? J
    I’ll try to answer for eventually questions.
    And thats the results:

    nice piece of engineering. You must have metal welding skills;)

    The tensioner concept is similar to Stringway's ;).

    I don't understand how it produces the same tension regardless of rod angle :confused:

    Does the small rod on the red mounting move, or is it fixed?

    Neil, from the series of photos above the rod that the string goes over do move. I am just hypothesizing that the rod keeps the string, under tension, as parallel to the frame as possible.

    The frame supports are just about perfect for badminton. Very good job!

    Dear Neil,
    The small red part is fixed to the gripper, but it is move with lever (the angle between this "something" and lever is the same- about 90 degree)
    http://www.stringway.com/en/info/dropweight.htm - here is something about Stringway/LaserFibre tension system

    wow... impressive work mate, so how long did it take you to make? and how much did the raw materials cost?

    Coops

    The fundamental elements was created for 2 afternoons (my father can drill, cut, weld steel parts)- but before I planned everything with my brother assistance. For the next couple of weeks I improved, corrected all and made paint job (it's look strange and funny- I know :))

    About costs- I didn't buy anything, but I think, that raw materials cost shouldn't be higher than
    20-30$- against all appearances the construction is simple.

    BTW- I'm not an engineer- my occupation is very very different

    Michal,

    The design is sound. you just need fixed clamps and the entire system will be perfect :D.

    For floating clamps, It is not a problem.

    Just my opinion - I think it is a little challenging or may not be efficient to use fix clamp on that mounting system. It may hinder the hand movement during clamp/move the fix clamp. Unless, someone has some idea how to trim down some of those excess metal on the mouting system.

    Don't worry. Practise makes perfect :) My average time is 40-50 min (33min is the best).In comparision with DinkALot I'm very leisurely :p.
    BTW- pictures should be ok now.

    In my case the time is more due to the machine itself but i don't have time to update it so i continue this way, maybe this summer, i'll take it to the next level

    By the way here is mine

    http://www.badmintoncentral.com/forums/showthread.php?t=22353

    lots of similarity: my first mounting system is like yours but my larger green metal plate were blocking too many hole so i changed to a 4 point system.

    I'd like to have more picture of your tensioning system, i'd like to make mine like this cause on my machine always have to thigh a screw to hold the string. here my email adresse (benoit.aspirault@gmail.com)

    Also i like the way you made your inner mounting point but i can't do that on mine cause i also use it for tennis and i need my mounting plate to fits both type of racquet.

    You have right- both “machines” have lots of similiarity. I have seen your thread before- your pictures suggested me an idea about mounting system.
    I don’t have time now to take a new photos- maybe on the next week. If I take a new tensioning system photos , I will put here.

    About mounting system- I think that you can make a smaller metal plate for badminton racquets, it shouldn’t block many holes and machine will have 6 (or 8!) points mounting. For tennis racquets you will use larger green metal plate.
