glide bar clamps

[ryeung]

Does anyone have any experience with single action glide bar clamps on stringing machines? I have an Eagnas Flex 740 with double action fixed clamps and will be converting it to use glide bar clamps? Any considerations?

Thanks.

almost every stringer i see in HK uses the glide bar clamps. imho, they are much faster. there is only one clamping action and with the simpler structure, the clamp is more rigid and deforms less than the swivel clamp that most machines comes with nowadays. there isn't any point of using swivel clamp in badminton.

another trend i see is that stringers are starting to not use the built-in clamps anymore. they get a pair of the Yonex flying clamps/clips and they can do all the stringing work with those and they are much faster and easier to use.

Yup i agree with Kwun.. it does make the work faster. however we should add extra 2 to 3lbs to compensate back the tension that are lost while stringing on a glide bar clamps.

Yes, I agree. Have been using glide bar clamps for four years now, only one minor problem, one of my glide bars sticks on the rails slightly.

I have been using flying clamps for over a year and they are very good, improved speed and ease of stringing. Only flying clamps should not be used on first string of
stringing as they anchor off another string, and with the first string there is no other string to anchor to.

You can make a simple "start kit" for this case. I use a piece of string tail (about several inches long) attached with a key ring. Once you try to "grip" the 1st string, put the simple tool in the adjancent gromment, and it will give u the "2nd" string right next by.

Using flying clamps, is there any clamp twist when clamped? The main reason I want to modify the machine is that the swivel clamps do tend to get in the way.

Why would there be tension loss? Since I will be making all the parts, except for the clamps themselves, I don't expect there to be too much play in the glide rails. Just enough for the rails to slide smoothly. Certainly no more that the play between the swivel clamps and the posts.

yes there is. there will be a marginal loss of tension as a result.

That's another reason that "consistent pulling" machine tend to have higher tension.

LB, why are they related? the tension loss with the clip happens after the machine releases the tension. as a result, the loss from the clip should be independent of the type of machine being used...

I would like to thank everyone for their input. I have ordered a pair of glide bar clamps and will go ahead and make the assembly. Don't have a lot to lose as the cost for the conversion won't be that high. If it doesn't work out I can always try the flying clamps or go back to the dual action clamps.

What I mean was, for "consistent pulling" machine, with the pulling motion, it should minimize the neg. effect of "twist" (string being bent right after being clamped). Once u put lvl to be horizontal, u will see the "twist" disappeared (or, almost).

However, crank machine seems not being able to achieve the above effectively. I might be wrong, since I've never used crank machine, but just watched other stringers using that twice.
