Phil, this is my jib setup...
Its a turning block which has a t-terminal one end, and the forestay wire spliced onto the other. The jib halyard runs through the block so you have 2 loose ends. When I am rigging, I tie the 2 loose ends onto my boat breaker to pull on the tension, attach the forestay and then take the boat breaker off. I then tie one end of the halyard to the top of the sail and zip the other end into the jib, hoist the sail and then take the loose end round through the forestay chainplate, under the kite sock and through to a clam cleat which I have on the floor. This then acts as a jib cunningham. The excess tucks into a pocket on the underside of the sock.
I'll get an actual photo of it this weekend if you like as I know my MS Paint skills are a bit ropey... and I dont have time to make you a 3D cad model this second!!
