AlllllRightyThen! You want to get the true skinny, you gotta talk to the right people.
This is number two, and, including the time it took to tap some nails into a board for a jig, took less than an hour to twist and serve! I just got back from putting about 40 arrows through it, and no sign of unraveling! I reckon the next one shouldn't take more than 20 minutes.
Thanks everyone!
