    strung a Babolat PST Ltd (18x20) last night on the x-2, gamma syn. gut as main and a very plastic-feel poly as cross. I was weaving one ahead and not doing any hard pull.

    I noticed that when pulling the cross, if I let the already horizontally set tension bar to rest, it would continue to drop but very slowly. So every cross I actually had to wait for the tension bar to settle before moving to the next step. This cost me a lot of time (well over an hour to do the cross).

    So is it necessary for the tension bar to settle? How can I speed up the process?

    its normal i have the prog 2000 and that happens to me to. Poly needs time on the mains so i can see how it could need more time on the crosses. However I've never noticed any real issues with it. Still I'm not one of those guys who's strung every racket out there with every string, so .... uhh pinch of salt.

    It does happen. What I do is to raise the lever up a little bit as it is passing the horizontal level. Don't know if this is the right way to handle it. However, the approximate reading from stringmeter appears to be consistent (enough).

    Pull all the slack out on the cross and pull harder by hand before you put the string in the tensioner and pull tension. This will minimize the amount of string you haven't pull tight yet. Poly shouldn't be stretching a lot... syn yes, but not with poly. Your crosses must have just been loose.

    When pulling mains the only friction point you have to overcome is the frame. When pulling crosses there is an additional friction point at very main. The more mains the more friction. Tugging on the string to straighten them out help a tiny bit to over come that friction and keeps your strings straight, so that a good thing for a couple of reasons. Also after tugging a bit on the string your tensioning it may be go and go up to the previously strung string to straighten it. The if you want you could adjust the bar again if it is greater than 5 degrees below level. But all this takes time. If your racket isn't centered on the stringer's pivot point either the crosses at the top or bottom will be longer and the longer the string the more the stretch and the more from level you will be. So it take some getting used to.

    What you should be looking for is consistency. If you pull on a cross for 5 seconds at 60 pounds you will have some stretch. If you pull at 60 lbs for less than 5 sec you will have less stretch (string loaded tension) and if you pull for greater than 5 sec you will have more stretch. That isn't consistent.

    If you like your crosses tighter or looser there are two things you can go either raise or lower the tension or the time you pull them. Changing the tension is by far the best.

    With a drop weight the bar does not have to be perfectly level every time to produce a consistent job as long as it is +/- 5 degrees you good.

    I like to wax the mains with a bees wax candle toreduce the friction. It Seems to work For Me

    The wax on the mains will help but it will transfer to the crosses and get in the clamps requiring more frequent cleaning.

    I don't think you have to let your tension arm settle on the poly. As Irvin stated as long as you are consistent with you technique, you can decide whether you wait or clamp immediately.

    One thing to keep in mind though: make sure your tension arm isn't continuously dropping because your clamps are too loose. To check for this, watch how much your clamp or strings move when you are releasing the string after clamping it or watch the previous string that is clamped while you tension the next string. I am mentioning this because especially with hybrids using strings with different gauge and material, I adjust my clamps for the mains but don't always remember to adjust it back when starting the crosses.

    In addition, I try not to tension poly too long. Polyesters are mono filament. Monofilament doesn't respond to stretch the same way that multifilaments do. Imagine stretching a wire compared to a rubber band. So with that in mind, as long as you're tension arm isn't dropping to quickly you can just clamp off and continue.

    You guys do some weird stuff to complicate things. Just string. Wax?... :rolleyes:
