To use diablo or not?

using the the diabolo, the diabolo bears the majority of the tension as the string tightens around the spool so the gripper doesn't need to clamp nearly as hard on the string to hold the string from slipping.

With or without the diablo the gripper holds one end. If you are pulling 60 lbs of tension the gripper holds 60 lbs of tension.

You guys are looking at it like this. If I wrap a rope around a tree enough times there is going to be a lot of friction between the rope and the bark on the tree. If I hold one end of the rope tight enough to keep it tight the friction between the rope and the tree will allow me to hold a car back. If that car breaks the tree off though you sure don't want to be hanging on to the other end of that rope. LMAO

Big difference

Just in case you want a preview of what you are going to see I just did that. A 10 lb weight weighs 10.63 lbs hung from a string and when I wrap the string around my diablo it weighs 10.69 lbs. I think the reason for the 0.06 lb difference is the weight was free to swing when I did not use the diablo and when I did the string touched the the bar the crank slides on and that little bit of friction caused the difference.

You guys are too funny. Go on run you own test.

Your test is not designed to test the issue we are discussing, just to prove your stance. Better to wrap the weighted string around the diabolo & measure the force on the other side of the diabolo. That is what the linear gripper is seeing.
Unless you are saying that the diablo does not offer any resistance to the pulling force, I don't understand how it's not obvious? Oh, or you just playing with words as in the "speed stringing" charade?

Here is a good experiment for you guys to try out. Get youself a very strong steel cable with a hook on one end. Wrap the cable around a car wheel and place the hook on the hitch of a car. Clamp the other end of the cable around your neck and tie your feet around a big tree. Tell the driver of the car to drive off and see it you can hold the car back. Come back and let me know what happens in your next life. LMAO

'bugeyed' you never responded. What causes the the linear gripper to close down on the string? Are you afraid you prove yourself wrong? Simple enough question why are you not responding? I would like to know what you think causes the linear gripper to close down on the string.

Have you been drinking, 'cause your analogies have been way off the mark! "If the tree breaks"???? Yeah, if the diabolo breaks, the gripper will feel the full tension, but that is not the case here.

Some, but not the full pulling tension. The diabolo is supporting some of the "weight".

I ran another test of with the weight. Free the weight weighed 10.63 lbs and when wrapped around the diablo 10.56 lbs. This time it was 0.07 lbs less. Now if the friction of the diablo makes a difference why can't the scale detect it?

a 10 lb weight will weigh 10 lbs regardless of whether a diabolo is used or not.

the question is without the use of a diabolo, how much clamping pressure does the gripper need to apply to prevent the string from slipping through the jaws? and how much clamping pressure does the gripper need to apply to the string when a diabolo is used? your test can not possibly measure that.

after the speed stringing and now this, i think irvin has fallen off his rocker.

I suspect that Irvin is going to come back & point out that he is talking about his machine that has a fixed diabolo that doesn't move with the linear gripper. At least that's what I think he said a few posts back. To clarify, my question was in regards to a Babolat type diabolo that is fixed to the moving tensioner assembly.

I reread irvins previous post about the Gamma diabolo & I think he was just talking about the tension head rocking to release the latch. So, the process should be the same on that machine as a Bab. Guess I was just trying to make sense of Irvin's argument.

i've owned the gamma 6004 as well as the wise with the diabolo that irvin uses. both are mounted to the tension head and move together as one unit as tension is being pulled. now maybe he's customized his machine, but i don't think so.

EDIT: I am not playing with words. You guys are either wrong or messing with me this time. Here's the most likely scenario. I just don't know it, but I'm wrong.

fixed your post for you.

The diablo supports none of the weight. If it did the weight would weigh less.

With or without the diablo the tension on the string is the same. The gripper does not apply a gripping for to the string. The string moved the linear gripper forward. As the gripper moves forward the ball bearing riding in a track close the gripper plates and the gripper plates apply pressure to hold the string. Te greater the resisting force applied by the string the more the string is squeezed by the gripper plates.

I know of no stringing machine where the gripper does not move with the gripper. I have a Gamma stringer and the diablo if fixed on the tensioner and moves with it. The front section of the gripper assembly is a pivot for the gripper but any less movement of the gripper plates and the diablo is so slight it can not make a difference. Take the Wise diablo it is bolted to the gripper assembly and gripper plates inside the linear gripper move the diablo again is fixed in relation to the gripper assembly.

I believe it was tbuggle that said earlier sometimes he used the diablo and some times he didn't. He didn't say whether he could tell the difference. I bet the cant. Take the Wise tensioner. Mine does not have a diablo. If i add a diablo will my tension be off?

i give up. irvin, you win.

I tried to use RJYU's test to see what would happen. Used Technifibre black code at 66 lbs and there is not crushing of the string whether I use the diablo or not.

Irvin, the gripper IS applying a gripping force to the string. It grips harder the higher the tension, at least until it reaches it's end of travel. As for the first statement........the diabolo certainly supports some of the pulling force! THAT'S THE WHOLE POINT!!

Well thanks for responding I thought you were afraid to speak up. So if I use my lockout stringer and pull 60 lbs of tension with the diablo I should be able to put a scale inside the frame a take a reading of how much tension is being applied to the string. Correct?

Be very careful in choosing your words I am going to trap you and prove you are wrong along with everyone else.

the tension inside the frame will be the same whether you use the diabolo or not. since you think otherwise, you clearly do not understand the purpose of the diabolo and what it does.

[mad dog1]

when you use dental floss to clean your teeth. do you wrap the floss around your fingers? or do you attempt to grip the floss as tightly as you can?

if you wrap the floss around your finger, why do you do it?

Never ever did I say the tension inside the frame would be different depending on whether I did no did not use the diablo. I am going to go on record right now and say it will be the same.
