i have already created the string launcher catapult but I am having a difficult time storing the string. I tried making it into a loop but it does’t reach maximum expansion. How can I make it work better? Also does the string have to be 1/4 or 1/8 or can it be inbetween that size range? We are using pulley kit string size. (1/8)
It can be within those measurements. Here’s a topic of mine with answers to your questions How to bundle up string for Horiz. Expansion
But basically you can coil it and put it in a little basket.
String can be anywhere in between 1/4 and 1/8 inch. We sorted string by having a long tube made of two c-channels and made a tool to ram string in. We tried other coil methods but this one worked the best.
Thank you for that forum post link.
I found the “coil knot” tutorial and the string launcher shoots much farther now.
This works well for us (string is too thin, we are going to change that):
