    I have watched Jorgs video on the physics of slingshots and how tapered bands are better than not tapered and why, I also read many strands are better than one single piece of rubber (not sure where and not this forum). This got me thinking about cutting the bands into effectively ribbons. When entering the data for a butterfly bandset into Jorgs theraband gold calculator it came out with 27cm long 4.16cm tapered to 1.67cm one piece per side (this was for 9.5mm steel). Is their any advantage to cutting the pieces into smaller strands? I was thinking into 3 or 4 pieces. Of course the draw weight should be identical (i do not yet have means to test this) and as far as I understand it will decrease band life. Whilst I assume they will heat quicker than one single piece I also assume they will cool quicker? So is there any advantage and does it out weigh the disadvantages?<br><br>I apologise if this has been covered in previous posts, I have looked in the forum and watched most of Jorgs videos and will keep researching but again sorry in advance if this is noob question, feel free to ignore if so <img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2">

    By the way I should also add that whilst common sense dictates that Jorg has done much work on the subject so the fact his calculator suggests one single piece of latex and that is no doubt superior to my idea, I also know if you don't ask you wil never understand <img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2">

    If you use real strong bands with light ammo like 9.5 mm steel you will get a real bad hand slap, also it is not very efficient. If you cut the rubber to small tapered strands with a small pouch it will be very efficient. When I shoot 9.5 mm steel I use single layer very very tapered bands and it is very fast. Much more fast than if you we're to shoot with big heavy bands because they create drag and are heavy themselves, also the draw would be heavier, so you are putting in allot more energy into the bands than you are really putting into the ammo. About cutting them into strips rather than folded strips that's just preference, also it's a little faster to just fold them, but cutting strips is cleaner looking.

    Thanks very much for your answer <img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2"> I guess with strips rather than one single piece there is the advantage of less drag like you say. I just wondered if cutting the bands into as many ribbons as possible would have the same sort of effect as tapering, greater heat energy as the pieces are smaller. I have tried it but don't have chrony so have no idea if its generating anymore power.

    if you cut them into thinner strips they will tear faster. It will not have the same effect as tapering because when you have tapered bands the end near the pouch is stretched more than the end at the forks. So the rubber that is stretched more will want to move faster, as a result it accelerates the pouch faster. Rather than the whole band set un stretching at the same time.
