...The "shot line" (fishing line) is tied securely to the shaft, just above the knock of the arrow, which is tipped with a bolt instead of a "tip". The shot line must be removed from the spool and laid-out on a board or other flat surface in a sequence of "rows"...
I used a .30 caliber bullet shell full of sand over the tip for weight and to make it blunt (or a bunch of nails taped
around the tip if I have to improvise.) I drilled a hole though the arrow shaft just in front of the knock, then
passed a loop of fishing line though this and back over the arrow. That makes it easy to remove the arrow without
having to untie anything.
I used to lay out a tarp to flake out the line, but now just flake it into a bucket instead. That works at least
as well, if not better, takes up less space, and I can leave the line in the bucket between uses. I tie the end
of the line to the bucket handle then just feed the line into the bucket, letting it lay however it does. I've
never had a problem with it tangling.
