It would appear that you would be the right person to answer the following question about STRAIGHT cuts, since you know about cutting bands. Given: Slingshooter has a draw length of 28" Given: The brand of band is "Duraband" Given: The elongation of the Duraband is found to be 4.5:1 If we divide the draw length by the elongation ratio, the usual procedure, (28/4.5) = 6.22", the relaxed band length. HOWEVER, when pulling the band to it's maxi,um stretch once attached to the slingshot, the required 28" cannot be obtained. To reach the 28" draw length, the relaxed band length needs to be 8.75-9", not 6.22", quite a difference! Why is this? Many thanks!
Hi Linder. Great video. I understand the math and the logic. However, does this formula hold up ‘in the real world’? It seems to me that when the mass of the ammo (and its inertia,) is added to the equation, that the Straight Cut band would be storing more energy because the band itself is larger than the Tapered Cut band. So, does which band cut moves ammo faster? Can your hypothesis be proven with a chronograph? Thanks, and keep up with these great videos! You are appreciated. ;) -Clint.
Dear Fellow Slingshooter, your argument that a ball fired from a trapezoidal rubber is faster than a ball fired from a parallel one because the centre of the rubber travels less distance is flawed. It is not the question of how much faster the ball is than the centre of the rubber. The question is how much faster or slower the parallel (say 16mm) rubber is, than the trapezoid (say 20-12mm) which is the same amount of elastomer material. I suggest the use of a measuring instrument: A fishing scale (force gauge). For both rubbers, make a graph, plotting the tensile force as a function of length from 0% elongation (resting position) to 500% elongation (extended position) in 10 steps. You will see, that more force is required to pull out the trapezoidal rubber because the narrow end is stretched out far more. (It is actually overloaded.) This extra force means there will be more force accelerating the ball, so it will fly out faster from the tapered bands. But this is not for free. You invested more energy into stretching it, you get that back.
Fantastic Demo man! I’m really enjoying this series you have going. It’s very well put together. Thanks 👏🏻👏🏻
You're killing it bro! Keep the videos coming!
man ..your explanation skill is just awesome...thanks for your videos
Really great! I hope you have many more topics to come! That's unique!
Linder doesn’t suck very smart guy and good teacher makes it easy to understand 💥
You are rock your explanation deserve hundred stars thank you🎉
"Knowing is half the battle" Great visual, allows us to see why it's faster.
Outstanding demonstration!!
Excellent demonstration. 👊
Loving your content!! All great videos!! Linder does Not Suck!!
INSTANT SUB!!!!! Because you are one heckova teacher!!!!!!!!!!!!!!!!!!!!!!!!! Thank you!
Excellent presentation.
Thank you, that means a lot!
Excellent demo thank you
Another great video!
Thank you for the video!
Regarding the pouches: how big the pouch hole needs to be in relation to the the ball size you are going to shoot?
What bands would you recommend for strong shooting or hunting? Can I get th good on Amazon?

@@MysticValleyDesigns Yes, it absolutely plays out in the real world, but don't take my word for it, try it out!

So, why the 2012 is faster than a straight cut?
Science.
