Trap,
A number 7 should be right for that bow.
The Shaft spider fits into the hole at the rear of the converta insert. The thread goes through the shaft and out a hole between the fletch and the nock, and is secured to the shaft with a piece of bent velcro. The other side of the velcro is on the belly side of the window positioned where the piece on the arrow can catch an be pulled from the arrow along with the thread. There is 1800 ft of thread, generally enough to do the job. It will work even on a shoot through. Nothing to tie on, no string slowing the flight, no string snagging on branches, no loud sound of string peeling off a spool. Just remove an arrow from your quiver and put it on the bow and shoot -same as always. The only problem was the other arrows in the bow quiver would sometimes get a rattle/pinging sound of the bobbin hit the arrow wall at the shot, the smaller the arrow diameter the less chance of that. On a rare occasion the bobbin will let loose of thread and it can accumulate at the nock end. I don't remember that happening to me, probaly someone else told me that. I still have a few around here, we used them for bear hunting back in the 80s.
