Starting mains with flying clamps, but easy?

#1
I string with a gamma X-2, 2 point and floating clamps.

I learned how to string from here and youtube. Found a clip on how to start mains with flying clams. It showed how to double pull strings to the chosen tension, clamp strings in the middle of the racquet head. Then string one string to one side and the other to the other side, and so on.

No problem until I started with poly's. It seems that my X-2 stringing machine doesnt get enough grip on both strings. So they it starts to pull one string and the other starts to slip and therefore pull more string to one side.

What can I do better or is there an easier way?

Hope it makes sense, thanks!

If clamps are slipping, clean them and adjust. If the rotational gripper is slipping, make sure the both strings are wound around the outside before insertion into the gripper. Make sure both strings are flat against the surfaces of the gripper. BTW, you will need a lot of slack since poly does not stretch very much. HTH.

I've never had problems with polys. Which starting method did you find on youtube? You say, "It seems that my X-2 stringing machine doesnt get enough grip on both strings." Do you mean the tensioner doesn't get enough grip? As noted above, clean your clamping surfaces. Use something like a toothbrush and something soft that won't leave debris with some isopropyl alcohol.

Have you tried this basic procedure?

Thanks! Just to clearify. Its not the clamps, but its the rotational gripper that makes it hard to double pull.

I learned from this video:

http://www.youtube.com/watch?v=jGo9X22vqGs

Around minut 4.30 he starts mains by double pulling and centering clamps.

The thing is I have nothing but difficulties with poly's. First I can't start mains with a starting clamp, because the poly's slip when I tension.

I have been stringing for a long time by double pulling, so its not like I cant get it to work. It just takes som tries sometimes..

Any recommendations for a good starting clamp?

I'll check out the thread on stringing guide for X-2! Thanks

^That's one of Irvin's videos. I'm sure he'll have some advice. I thought you might mention the YULitle version. The one I point out is a version that is also noted by the USRSA. However, it uses double-pulling to start, as noted in the description. I use that in the "guide" because it is probably the most simple to start with and describe.

Like anything here, there will be debate about starting clamps. There are numerous posts. But check this info out as written by TT's mighty moderator: (Post #215) http://tt.tennis-warehouse.com/showthread.php?t=207401&page=11 ;-)

I know exactly what you meant. When one of the 2 strings in the rotary gripper would slip, I would repeat and it would slip again. This also happens some times when I try to bridge a short end string with a starting clamp. Again one string would slip.

My solution is give the two string a twist before putting into the gripper. Instead of 1-2, now its 2-1. I'm not sure why it works but it does. I think it slips because there is unequal tension on the two strings because they are not perfectly perpendicular to the gripper. By giving a twist somehow the tensions became more equal.

Let me know if I works out for you.

When starting flying clamps like that without a starting clamp the only reason to pull tension is to get the strings going straight through the clamp, just hold the strings snug by hand as you place the first flying clamp and you will be fine.

Yeah … DON'T do this

twisting the strings then putting them in the gripper is not a good idea, if the strings are crossing or twisted one pushes into the other which can damage the string and that's probably going to be right in the middle of the string bed.

Of course this will hold better it's like having a big ridge in your gripper, kind of like the ridges in the jaw of a pair of pliers but just a single ridge.

Actually the two strings are not twisted in the gripper. They are twisted before going around the rotary gripper.
Perhaps not as bad as what I thought you were doing, but the OP doesn't have a starting clamp so there isn't any need to double pull in the first place. Even with a starting clamp you can avoid double pulling.

What I shared was a way for the rotary gripper to grab two strings at a time. This is needed in the beginning of stringing mains or using starting clamp when the last or 2nd to last string is too short to be gripped. I found that the one of the two would be slipping. Repeating the procedure rarely helped gripping both strings. By accident, I "twisted" the two strings once. Both strings are then both strings are then gripped.
