Thanks guys...
I actually measured it today and its 3,5 inches in the less thick side.
I guess i will have to find some place where i can saw it, since i dont have a bandsaw...
The tree has a knot near one end, should i saw through the knot and hope that i can left it out of the bow, or should i keep it in the middle of the limb?
Thanks,
Joćo Pedro
