Kegan,
Parachute cord huh? You remind me so much of my first year of building bows. I was taking free tie-down twine from the lumber yard for my strings because $8.50 for a role of Dacron B-50 was prohibitively expensive. I love the fact that you are doing what you can with what you've got. You took a D-bow, experimented with it by adding recurves, and then experimented some more. It would take me 6 months to build a pemobscot bow--you just dove right in. If you don't burn yourself out, you'll have a bright future as a bowyer. We need guys like you and Sean to popularize primitive archery for the next generation. Tell your friends.
