  We have technically improved the non-perturbative renormalization method,
proposed by Martinelli et al., by using quark momentum sources and sinks.
Composite two-fermion operators up to three derivatives have been measured for
Wilson fermions and Sheikholeslami-Wohlert improved fermions in the quenched
approximation. The calculations are performed in the Landau gauge on 16^3x32
lattices at beta = 6.0 for 3 kappa values 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.
