Yes, it does look like it should bend more, even if that spot is thinner then the outer limb... That's why I didn't srape much off from there.
Tradcraftsman: yes, there's a bit of reflex in the outer 1/2 left limb; you're correct about that slight hinge too, that's a thin spot... I'll have to scape above and below it to make it bend evenly.
ps: I'll try to take a better pic next time
