Just had a call from the local parks dept. who are generously offering me some white elm logs removed from the parks...
Question was asked if I wanted limbs as they generally have tighter rings which in theory should make stronger wood?

I told him I didn't know for sure and would check it out.....so, which do I want for selfbows or backed? Tight groth rings or less dense rings, which may have a thickness of 1/2" between them
