A constituent parton picture of hadrons with logarithmic confinement naturally arises in weak coupling light-front QCD. Confinement provides a mass gap that allows the constituent picture to emerge. The effective renormalized Hamiltonian is computed to O(g{sup 2}), and used to study charmonium and bottomonium. Radial and angular excitations can be used to fix the coupling {alpha}, the quark mass M, and the cutoff {Lambda}. The resultant hyperfine structure is very close to experiment. {copyright} {ital 1997} {ital The American Physical Society}
