@Smokey Plainsman, the tow worm is looking good. I would still put a pin in the tulip tip even though you won't likely be pulling any ball or wads from the bore with that end of the rod. That's the conservative engineer in me to make an extra effort to retain tips by physical means as well as using epoxy. The coil will grip the rod really well. I would make some shallow grooves in the rod end to give some purchase to the coils. But, after a few uses, the grooves will begin to form.
Real tow from flax is the best, but fluffed up jute, hemp or sisal twine works pretty good too. Cut the twine into 4 to 6" lengths and fluff the twine into the individual strands. Make a ball and twist onto the coils.
