i have found quite a lot of decent 1x2 red oak board at both stores, as long as i'm picky. in the self longbows i've been making from these, i've been turning out some passable 35-45lb youth/starter bows. i've heard it said, and my experience is starting to bear out that red oak is better siuted for wide limbs, as i invariably get more string follow than i'd like, and these bows have been loosing more cast after breaking in than i'd like. i'll next be trying wide pyramid limbs, tapered from 1/2 to 3/8 in thickness and hope to get better results.
my oppinion; red oak is a tolerant work horse for light to medium bows but i'm not sure how long it'll last for selfbows.
just my impressions.
