Title: Brown grain line possible crack, osage orange board
Post by: mrbxzzz on October 25, 2020, 08:24:35 PM: Hello, I decided to take a chance on the osage orange board sold by 3 Rivers Archery and was somewhat pleased only finding a slight warp in the boards with a stained grain possibly crack in one. The crack in question runs 6-7 inches down from the envisioned tip and was visible on both sides of the board, one side was a little less visible.

Looking for some feedback from osage boywers whether they think this is a definite crack or just a stained grain line, I thinking if it looks bad I have enough material to pike the bow and not take the chance on it failing at draw.

The board is glued up as a triple lam at 64 inches, bamboo back and paduak core ready to make a nice shorty around 55-60 #

Is the bow backed already? If so and the crack is on the belly I would fill the crack with super glue and go on with the tillering. Be sure to use thin super glue so it sinks down in the crack.
