Hello friends,

Many people wonder what is the best way to tie the bands on the pocket. My opinion which only engages me is that on an elastic material it is necessary to use a ligature which can follow the deformations of the material in order to limit the stress of the connection.

I use the classic technique of tying the bands on the pouch with an elastic band 2.5mm wide and 50mm long making 8 turns and a final knot. This ligature adapts to the deformation of the elastic during the phases of extension and relaxation when shooting, which limits the stress on the band. In addition, the ligature links can be cut in the widest part of the conical bands which have become too short after breaking because this part is the least elongated during the phase of extension of the band.

Everyone is free to have their opinion on this question and to use the technique of their choice, only the result counts.

Cuffs only for me after MANY shots with MANY frames and bands.
Under close stretch observation IMHO nothing "gives" more "play" at said connection.
Also have never had slip and easy to redo if not near perfect.
Using 2040 can see thru to see ink
pen marks for near perfect band lengths. Can also see if folds are well done!
Have some sets that I cant believe still shoot just fine.

I use amber tape, no problems with the longevity of the bands.
Moreover, if the latex is of good quality and the power of the bands is coordinated with the weight of the projectile, the bands do not tear at all, you have to change them only because of material fatigue, that is, the bands appear to be intact, but the speed starts to drop.

Interesting .What band material are you using ?

I use amber belt, 3 loops, nice and tidy. Than I roll 5 times in the middle of these 3 loops. After the double knot, I roll up the inside to the pouch, aswell as the outside. Gives an nice round end on both sides. Nothings sharp, always use that method, so far never had bands rip at the pouch or close to it. 👌🏼

Hello dear friends,
Thank you for your feedback. If other people indicate their technique in this Post it will allow beginners to quickly have access to the different binding techniques to make their choices. A photo will be desirable in order to visualize the result of each type of fixation. Can you also specify the rate of elongation during ligation.

For my part, the rate is 2 and I start the ligature at 1cm from the pouch in order to leave a little freedom in the assembly.

Question to the specialists of the dicipline: should we leave of freedom to the assembly of the pouch with the elastic as in the photo or to have a tight assembly?
Thanks you in advance for your answers.

I'm a newbie in the middle of experimentation with polypropylene twine using constrictor knot and crystal string using overhead knot. I'm trying out the cuff method next . I do feel though that tieing with other rubber elastic is the better low stress method but I'm not getting hang of it yet it comes out all bulgy as when I'm tieing band to frame it comes out bulgy . But like they say practice makes perfect great interesting subject mate happy shooting 👍

Hello freind,

You are right, to each their own method.
For me, I think that the constrictor node concentrates the stresses on a narrow zone while a ligature with contiguous turns distributes the stresses on a wide zone. The use of an elastic band to perform the ligature allows the ligature to follow the deformations of the groups (elongation, reduction in diameter, rapid contraction, ...) during the shots.
A ligature is simple to perform and takes less than a minute. It is less modern than the other methods but it has been proven over time.
And what to do with the remains of the tape? why not use them to secure the groups.

Everyone has a choice, we do not change a winning team. (y)

Have good day; :)

Amber belt in a variety of colours I use and have used from the start never once had a bandset snap ever at all alot of people tie to tight and to close to the pouch or max bands right out which I never do either 🎯👍👌🏴󠁧󠁢󠁳󠁣󠁴󠁿

I use chrystal string, three double twists, three knots on top, done. My bands last pretty long, elongation factor is imo more important for band life than the material used for tying.

To each his own, but a simple constrictor knot with cotton butcher's twine will get you shooting in a lot less time with a lot less fuss and will not cause premature band failure.
Is constrictor knot with polypropylene twine not a good idea then ? 🤔 I got the method from Keith dieton mind you the vid was 7 years old lol thanks for advice

Hi mate I was put off using ordinary bands thought cuts of thera be better but old skool methods always proves test of time what dimensions elastic bands to use is best ? Thanks
