    If I want to string a racket using a 2 piece 50/50 pattern with flying clamps, should I just string the crosses like I would with the mains?
    Is there any video about it? (flying clamps)

    I have strung a prince exo tour using this method.
    I had 3 problems:
    1. I have a gamma progression 200 and the string gripper couldn't grip 2 strings at the same time(for starting the crosses). Is it possible on this machine?
    2. In my first try, there wasn't enough string for one side of the crosses. How do I know in wich hole to start?
    3. In this racket, the crosses can start only on one side of the racket. How will I know if the string will get there?

    1) starting is a problem if you don't have a starting clamp or start pin. Using the 2 piece 50/50 method you're going to have to start your crosses the same as the mains.

    2) when string a racket with O ports on the side when you string the crosses from top to bottom the tensioned string want to come to rest in the top portion of the O port when it needs to be in the bottom portion. Once you get to the pivot point of the turntable the string wants to pull to the bottom of the O Port. If you have the ability to adjust the 6 and 12 supports separately (and you do with the Progression) you want the 6 o'clock support down as far as you can get it. This way there are fewer ports above the pivot point. Then you start with the cross just above the pivot point. With that cross string perpendicular to the mains it will go into the top of an O port on one side and into the bottom of a port on the other side. The side where the string goes into the top of a port is the string for the top portion of the racket. Count the number of crosses you have and make sure you have enough string to string them. This really is not a 50/50 as the two halves of the cross string are not equal.

    3) the crosses can start on either side of the racket dependent on where the pivot point is located. Just do as I said in step two. If you're stringing a Prince racket one piece the short side can only tie on one side but it can start on either side. If you get the crosses going through the ports correctly they will be able to tie off at the correct points. If you tie off at the correct point the string routes through the ports correctly.

    First, I do have a starting clamp, and I started the crosses like I would start the mains(From your video- starting mains with flying clamps).
    I didn't understand your second answer, but what I'm saying is that I did finish the racket and it came out pretty good, but I coudn't start the crosses like you showed in your video- stringing o3 rackets- the solutions.
    As for the 3rd question, the crosses are tied of in 2 grommets(one for each edge) wixh are in the same side if it matters. I need a safe way to know where to put my starting loop, so I can get to those tie off spots.

    For starting your mains then run in the two center mains and clamp one outside the frame with a starting clamp and tension the other. Clamp the two center mains inside the frame as close to the frame as possible. This will be on the same end as your starting clamp. Tension one more main (at least) on the same side of the frame and move the clamp to the other end. Now tension the string with the starting clamp, remove the starting clamp and clamp the two center mains inside the frame.
    The bar the 6 and 12 supports connect to pivots on a point on the base of the 200. That is the point the whole racket pivots on when mounted on the stringer. If you move the throat (6 o'clock) support to one end of the bar you pivot will be as high on the racket as possible. If you center the supports on the bar your pivot will be centered on the stringbed. The two string on either side of the pivot point are the two strings you want to start with. On one side the two strings will be in one O port. Place the starting clamp on the lower string outside the frame and tension two cross toward the top. Then tension the string with the starting clamp and one more continue string two on top then two on bottom until the top is done then finish the bottom.
    As long as you loop rests on a portion of the frame connecting two O ports you can not go wrong. If you loop is inside one port you can't get started. Don't worry about the tie off they will work out. If you string from top down you have to fist make sure your tie off are on the correct side then you don't worry about the ports.
