Title: ELB Build and crack in Wood and Question
Post by: mtbow on September 15, 2016, 01:47:34 pm: First attempt at any bow build. ELB attempt using red oak and backed with 1/8" hickory. Just finished cutting out on bandsaw and found this hairline crack in wood near handle. 2 images show the crack. Can this crack be repaired/fixed with any hope for bow. It doesn't show coming out the other side of bow. Crack is on the belly side. Will be tilling for 45-50lbs at 26" Or is this piece of wood a good backyard fireplace warmer over a good shot of whisky?
I was thinking the crack maybe filled with CA glue? What say you all. Images below.

The cracks look more like honeycombing so there is probably more of them hidden within the wood if so.

Even I know what bandsaw tracks look like, Jawge. ;D
