    On the TW video for the crosses it shows 3x crosses are threaded with no tensioning then the 2nd cross is tensioned.

    Any idea why the 1st cross isn't tensioned?

    Why is the next cross threaded before tensioning the current one?

    Thanks.

    Just I method I use to start crosses as I don't like to pull tension directly against a clamp. After stringing the cross and tying off at the bottom I come back up and tension the top cross and remove the starting before tying off.

    I think I tied off the end of the string for the crosses then pulled the 1st cross - I'm not sure why I would be pulling against a clamp?

    Irvin is referring to starting the crosses with a starting clamp. If that was the case, then pulling the first cross is right against that clamp.

    In your case, it sounds like you're using a starting knot. If that's the case, I'd assume that the first cross shouldn't be tensioned anyway, or else that would cause a higher chance of pulling the knot through the grommet.

    You are suppose to use a larger knot (starting knot) when starting cross strings if you do not want to use a starting clamp, and tension each string .
    You do not want to use A finishing knot as a starting knot, as a finishing knot is smaller and can pull into the grommet more.
    That said I start cross strings similar to starting mains.
    I weave 2nd cross, weave 1st cross.
    Pull both together to set anchor clamp on 2nd cross inside frame farthest from tensioner.
    Pull 1st cross string, clamp, tie off with finishing knot'
    Weave 3rd cross.
    Pull 2nd cross, remove anchor clamp, clamp 2nd cross.
    continue as normal.
    I sent this to USRSA and this was published in their magazine.
    According to USRSA each string should be tensioned.
    In the USRSA Racquet Service Techniques manual Ch.2 is is in bold print to
    "Always pull tension and clamp one string at a time"
    The way this video was shown, I question if stringer would have passed the stringing portion of exam by not tensioning top cross.
    Does it matter, I doubt it. Should top cross be tensioned, I believe so.
    I am sure many will disagree with this, so if I am wrong then so is the USRSA.

    I do not exactly leave the top cross untensioned, but I tension about 1/3 of the top crosses at lower tension than the rest. It adds softness to the top of the stringbed, which otherwise is quite dead.

    If you leave any of the crosses (or mains) untensioned, they will ride up (or down), and form an arch. It will look like a really badly-done stringjob.


    I suspect skipping top or bottom crosses will do the same effect -- soften up those areas, but without having to go to low tension, or leaving them untensioned, which is visually bad. I will try that soon.

    I still use a starting knot (a bulky knot) to start my crosses. The only thing I do differently is pull the first cross at a slower speed. Never had any issues with the knot getting sucked into the grommet or string breaking.

    The top cross in the Video the OP is asking about is tensioned it is just not tensioned first. I tension the second to the last cross and then the top cross.

    BTW if there was no tension on the top cross I would need a starting clamp to hold it would I?

    Sorry, didn't watch the aforementioned video. I also follow the same method of skipping the first, tensioning all the crosses, and coming back to the top cross last.

    Many people don't tension the first cross right away so they can come back to it later and pull tension on that first cross, then use a finishing knot to tie off instead of beginning the crosses with a bulkier starting knot which would pull against the grommet when tensioning the first cross immediately. A starting clamp is used on the outside of the frame to hold the first cross in place.

    Your second question is what is referred to as "weaving one ahead" which allows for easier string movement through the mains since the previous cross has not been tensioned yet. If you were to tension each cross as you go, it would be harder to pull your string through the mains because there would be less space between them.

    The OP asked about the TW video specifically.
    On that video the stringer pulled both top and 2nd cross with one pull with a starting knot.Some stringers will go back to pull the 1st string but not here as he used a starting knot.
    Like I said, I'm sure that is okay, but in reality you are suppose to pull each string separately and that is USRSA guidelines. That was not done in the video. I would not recommend that way to string as in video from TW, as you should tension each string separately, but to each their own.

    I pointed this out and several other errors in their video to TW. They didn't like the fact I was pointing this stuff out. Every string should be tensioned seperately

    First I have heard of Jim E's method of weaving top 2 crosses and pulling together as starting mains. This would avoid needing a starting clamp as you would be tying off the top cross straight away. Considering that I have had strings snap when using the starting clamp outside the frame for the top cross and then tensioning for tying off, this may work better for me.

    My one concern would be the angle of the string coming out of the frame for the top cross. Not sure it will be parallel going into the string gripper together with the 2nd cross?

    This is the way I use to start crosses, I no longer back up the 2nd cross with starting clamp like this picture shows, ( I use to have 2nd cross not only being held by machine clamp but also backed up with starting clamp when I pulled the top cross to reference tension, and since found that it is really not needed) , but as you can see, no great angle when pulling the 1st 2 strings. I had this photo in my file , as this was the one the USRSA published in their magazine when I submitted this way to start cross strings.

    "A picture is worth a thousand words". Thanks. I will be trying this next racquet as I think it will even speed up my stringing.

    I could never use a starting clamp for the top cross. I spin the racket rather quickly and a starting clamp would get in my way.

    As long as it's tensioned, not an issue. You could spin the turntable however quickly you desired and it would not be a bother.

    I was thinking more of hitting it accidentally and knocking it off.

    Not likely, but I understand your concern. It is on there pretty good. Jim E's method is a refinement and doesn't use the SC
