I'm new to the game, maybe 15 under my belt. Just for laughs I built a 3 piece from a pair of skis, just because, will it ever break, I doubt it. The bow is a total slug. limbs to heavy, but it shoots where I point it, its a center shot 15" riser.
Most wood bows I build now have backing, just like using diapers for a 3 year old, just in case.
