We have technically improved the non-perturbative renormalization meth
od, proposed by Martinelli et al., by using quark momentum sources and
sinks. Composite two-fermion operators up to three derivatives have b
een measured for Wilson fermions and Sheikholeslami-Wohlert improved f
ermions in the quenched approximation. The calculations are performed
in the Landau gauge on 16(3)32 lattices at beta = 6.0 for 3 kappa valu
es in each case. The improved sources greatly decrease the statistical
noise. We extract and discuss here renormalization factors for local
operators and moments of the structure functions for Wilson fermions.
