Yeah..ditto to gun doc....no go using figured wood(its called curly,birds eye,tiger,spalted,etc..)ANY kind of species of wood with these.....I'd even be leary of using it as a belly...I know some who've tried and had it fail or fret on them....IMO that kind of wood is only good for super thin veneers in glass bows(yuck...can't believe I even had to say that..lol ) or handle under n overlays etc where no bending is going on...I am contemplating trying one in a core in a tri lam(making it super thin)....but the jury is still out on that one and is still up to debate in my head....and I think everyone else explained well enough the why's on having smooth radiused transitioning fades
