Thenks for the build along.  I am very new to all of this and appreciate the post.  I've tried my first hickory board bow and followed your instructions as best as I could.  I had what I thought was a nice quick shooting bow at around 40# but after about a few dozen arrows I could hear popping in the limbs.  Thinking it was about to either explode or lift a splinter, I stopped shooting.  I noticed that you didn't scrape the back to "chase the ring"  .  Is this not required on a board bow?  I've built a few maple sapling bows and while they are very light in draw weight, I didn't have to chase the ring.  I would appreciate your comments. thanks again.
