    Is there a good visual or written description of how to clamp the first two mains. I have looked at sptennis.com but it shows flying clamps. I can't seem to find anywhere that helps me figure how to clamp and tension the first two mains. I was told to tension the first two together but that doesn't seem right. Any help or directions would be appreciated.

    Here are a couple of ways to do it.

    Start by threading the two center mains. Let's assume you are starting at the throat. Place one of your machine's clamps on 1L about 2.5" inside the frame next to the throat. You can back up the machine clamp with a starting clamp or extra flying clamp to help make sure it doesn't slip on the first pull. Now pull tension on the other string 1R, which is coming out at the top of the frame. Clamp it off next to the frame. Now thread, tension and clamp 2R. Your clamp will be right next to the frame. There should be enough room there since you left room for it to pass by the first clamp. Now pull tension on 1L while you release the clamps that are already on it and reclamp it on the other end of the string. Now thread, tension and clamp 2L. Now you have 4 center mains done and your clamps are side by side at the throat. You can now proceed to alternate from side to side until the mains are complete.

    You can also use a starting clamp on the outside of the frame on 1L instead of one the machine's clamps. Pull tension on 1R, then do 2R, then come back and tension 1L, clamp off with the machine clamp, remove the starting clamp and then do 2L.

    Hope this helps.

    Thanks very much. Your post was a bigh help. I will be stringing my first racket later this week and have been trying to visualize the process and was stcuk with the start. You have cleared it up. Thanks Gaines I appreciate your time and patience with us newbies.

    Question for Gaines

    Gaines,

    I have just gotten my machine and tried starting the mains according to your post. I seem to have some problems when I try to tension 1L. The crank does not lockout and the string seems to slip form somewhere (does not appear to be at the clamps). If I tension while it is still clamped it works ok but if I try to tension and loosen the clamp I get the movement in the strings. Should I tension with the clamp still tighetened or am I doing something wrong, or does it sound like a mechanical error? Good thing I am using an old racket and some strings I really wouldn't use that came with the machine. Spent about 45 minutes on this process and just can't seem to get it right. Thanks for your patience and any hlep you can give.

    coach, if you clamped on 1L 2.5" on the inside of the frame and then threaded, tensioned and clamped off 1R and 2R you will have a clamp on 2R next to, but inside(nearer the frame) the clamp on 1L. You then pull tension on 1L while at the same time releasing the clamp. You need to get the tension head close to the frame when you insert the string into the gripper for this pull. I sounds like you are starting the pull with the tension head too far down the track or are leaving too much slack in the string for it to reach the set tension and lock out. The most likely place for the string to slip in the clamp on 1L is when tension is pulled on 1R or 2R. You can check for this by putting a mark on the string next to that clamp before pulling tenison and see if it moves. You may need to tighten the clamp more than normal in this situation or use a spare flying clamp or starting clamp to back it up. Hope that helps.

    The above instructions are for a machine with dual action swivel clamps. If you are using a machine with glide bar clamps they may be thin enough so that you don't have to clamp off 2.5" inside the frame on the first string. You can go ahead and clamp as close to the frame as the clamp allows.

    Thanks Gaines

    Again, thanks Gaines. I appreciate your patience. I will certainly double check what I am doing and try what you said this evening.
