    Hi, I'm a novice in stringing. I'm trying to string on a dropweight machine and have some questions.

    1. How should I use the clamps when starting? I use a machine with two fixed clamps. I watched several videos but they all have different ways to start. Some would clamp both center mains with a starting clamp, some would use a fixed clamp to clamp one of the center mains and pull the other. Which is the correct way?

    2. The drop weight is not dropping... I firgured I should drop the weight and it would go all the way down, then I tweak a bit each time until it goes flat. But even on the first pull the drop weight is not dropping to flat level... Am I doing something wrong here?

    Thanks!

    I can’t speak to question 1, but 2 is a simple fix. If you are working with a string that doesn’t stretch much, leave some slack in the string before the string gripper.

    Or more simply, start with the bar down rather than up.

    Hi @mrravioli,

    IMO, there is no single "Correct Way" to start stringing mains. Use whatever method you are comfortable with and works for you.

    Obviously, if you use a Starting Clamp method (eg. Yusuki method or a variation of it) then you need to have a Starting Clamp. If you don't have a Starting Clamp then you can use the Fixed Clamps of the machine or Floating Clamps if you have them.

    Personally, I use the Yusuki method outlined by @Irvin in one of his early videos. I do have a Starting Clamp and since I only string my own frames I'm not concerned by any potential damage to the frames that can be caused by mounting the Starting Clamp to the outside of the frame.

    @Irvin has come up with a Starting Clamp solution to protect the frame from being damaged which I would use if I was stringing other peoples racquets. He has made some videos to describe it so check them out.

    Starting mains will depend on if you have a good starting clamp or not.

    Here's how I do mine with a starting clamp:
    -feed the first main on both sides through the racquet.
    -put the starting clamp outside of the frame on one of those mains.
    -pull tension on other main
    -clamp the main with the starting clamp as far away from the tensioner as i can (actually not quite as far as I can ... maybe about 1 inch less so the other clamp has room on the 2nd main)
    -clamp the main that is tensioned as close to the tensioner as possible
    -run 2 more mains on the side without the starting clamp (pulling tension and clamping each)
    -pull tension on the main with the starting clamp
    -remove starting clamp
    -continue until 3 mains ahead on one side and go back to the other side.

    If I didn't have a starting clamp: (on a drop weight)
    -feed the first main on both sides through the racquet.
    -with one hand pull both mains so they go straight through the racquet
    -clamp one main as far away from the tensioner as i can (again leaving maybe 1 inch for other clamp to fit next to it on other side)
    -while maintaining some hand tension on the clamped main to keep the first clamp from falling feed the other main through the tensioner and apply tension
    -clamp this main closest to the tensioner
    -run 2 more mains on the same side (tension/clamp etc)
    -pull tension on the main that is clamped away from the tensioner
    -move that clamp to the tensioner side
    -continue until 3 mains ahead on one side and go back to the other side.

    double pulling on a drop weight is a pain in the rear - so notice both of these methods use no double pulling

    for #2 - I'm guessing you are using poly which doesn't stretch much, like someone said leave a little slack before the tensioner. With other string types you won't have to even bother as they stretch more.

    While your method does avoid pulling two strings at once (BTW, I don't call that Double Pulling. For me, Double Pulling means pulling the same segment of string twice.) it places additional pressure on the Starting Clamp and on the frame at the point where the Starting Clamp makes contact with the hoop. With your method you are pulling the string being held by the Starting Clamp.

    Personlly, I pull both centre mains together. Then use a Fixed Clamp to clamp one of the Mains at the far end of the hoop. Then I attach the Starting Clamp on the outside of the hoop at the Tension Head end. Then I release the Tension Head. And then proceed to thread and tension in the normal manner never going more than 2 strings ahead on each side. With this method, tension is never pulled with the Starting Clamp in play. So there is no risk of the Starting Clamp flicking off and minimal risk of it causing damage to the frame.

    You do that on a drop weight ?

    When you start your mains you want to hold the string while you damage the string as little as possible. With fixed clamps and no starting clamp I would hold a firm hand tension of the 2 center mains and clamp as close as possible to the loop with one clamp then tension the main that is not clamped. Tension and clamp at least one more main so both machine clamps are side by side. Then tension and clamp at least 2 mains on the opposite side.

    If your weight is not dropping there could be a couple of reasons, but it all boils down to one thing. There is not enough stretch in the string to be pulled by the weight. If you’re using a stiff string like poly or Kevlar and you have it doubled it will take a lot of tension to stretch it. I would not pull two strings with a drop weight but hand pull to set clamp. Also the higher the above level the weight is when it starts to drop the lower the tension. You will get maximum tension with the weight bar horizontal. Unless you have a couple of extra hands it is hard to grip the string on a DW with the bar level so it may be better to start with the bar en grip the string and allow the weight to drop from just above level. Then you can repeat the dropping action until the bar is fairly level.

    Several good suggestion above already
    buy a starting clamp when you get a chance, good stringing investment
    will make this process alot easier..

    go on youtube and look up your machine, and/or similar for stringing ideas,, im sure there are several youll find useful
    good luck and keep stringing
    it gets easier with practise
