    Hi,<br>i try to set with joerg calc the max power of bands (max tapering and max force in elongation all set to 9) of<br>respectively 1 x side and 2 x side. Coz i wanted to the max power for each band per side.<br><br>the max for 1 x side was MORE than 40mm at fork side<br>the max for 2 x side was LESS than 40mm at fork side<br><br>Why? I thought to get the same wide at forkside of the 1xside in the 2xside before go to next step (3 x side)<br>I hope u can understand me <img src="http://illiweb.com/fa/i/smiles/icon_biggrin.png" alt="Very Happy" longdesc="1">

    Zwillie, this time i'm not looking for speed <img src="http://illiweb.com/fa/i/smiles/icon_wink.gif" alt="Wink" longdesc="15"><br><br>i do not choose the 1 or 2 bands per side.<br>I just increase the ammo weight to the limit 1/2 per side and 2/3 per side, to get the max band wide at fork and pouch for 1 and 2 bands per side<br><br>and i found that at max for 1 x side i got at fork more than 40mm<br>while at max for 2 x side i got at fork less than 40mm<br><br>i thought to get more than 40mm at fork for the 2 x side too...

    Oh, if you took half of the ammo diameter you don`t choose the half of the ammo weight.<br><br>V = 1/6 Pi * d³<br><br>It is a factor of 4.<br><br>If you double the diameter you have four times more weight.<br><br>Is this what you mean? <img src="http://illiweb.com/fa/i/smiles/icon_scratch.png" alt="scratch" longdesc="33">
