hi joe,
i have a limb from an apple tree that is about the same demensions.
i scraped all the bark and cambium layer off of he wood,sealed the ends.
i then analyzed the limb and decided which was to be the back and the belly.
then took my draw knife to the belly side and took off about 1/4 to 1/2" of wood.
lightly sealed the back and sides with wood glue and stuck it in the corner.
its been there for about 9 months now.i am hoping by next fall to make my wife
a new target bow from it.
and i would not try and split them with a band saw.you could end up wrecking them.
if you split them you might not have enough wood on either,especially the smaller one,to make a decent bow.
not to mention you might violate the grain severly.
jmho
peace,
tim
