Last is to tighten the snot out of the last knot, gently cut with a razor a tag end that you burn. As the tag end burns and the molten serving material reached the knot you wet your finger and push down into the knot to make sure the last knot doesn't come loose. Same for the other tag end and thats it. you can see the completed servings beside the rail. The rope cocker hooks cannot slip past it.
Henry, I hope you understand all this. If not let me know. I have found that I cannot make a mistake with this set up. I never have to adjust the string once it is cocked.
