I only tried Black Locust once. There were a Lot of very thin growth rings per inch, and I used a standard flatbow design. That bow shot 3 feet left, and I have it propped up in the corner with a message: How NOT to make a bow!!!
You've done very well, and your choice of forums is spot on. I've been on most, and this is the only one now. Expert advice, some constructive criticism, some outstanding bows to aspire to, and overall a great group to share your archery passion with.
I'm only an occasional poster, but frequently look for pointers or solutions to problems. Best site for me!
