    Hello, I was wondering if anyone of you have got a clue of what the numbers on the two scales about tapering and band stretch are indicating. I am about to build my own slingshot soon and I am going to try the "Hammer Howitzer" design.<br><br>Thanks. <img src="http://illiweb.com/fa/i/smiles/icon_wink.gif" alt="Wink" longdesc="15">
     
  2. The numbers on tapering as in the scale it gives you to chose from?

    you'll have to choose between bandlife and performance.

    Well, I mean that I have some issues understanding what I should type in the scale, it's from 1-9 I think. I mean, how do I know if I want "4" in tapering and how do I know if I would like to stretch the band "7"?

    its not so hard to decide <img src="http://illiweb.com/fa/i/smiles/icon_wink.gif" alt="Wink" longdesc="15"><br><br>if you prefer a long band life you have to choose low numbers in draw lengh and tapering...<br>if you prefer maximum power you have to choose high numbers. <br><br>i make my bands with tapering=5 and stretch=6 so they have a good compromise between life and performance
     
  7. The draw length numbers are how far you draw the shooter, the max rating is full butterfly style shooting. that should help you judge the length you are going for. (If you are not familier with butterfly shooting there is a video here on this forum)

    Thank you, now I got a better knowlegde of how I should measure the draw length scale.<br>(And of course I know butterfly shooting style, Jörg is really often using that type of shooting style.)
