  As part of our program to build a complete radio and X-ray database of all
the 3CR extragalactic radio sources, we present an analysis of 93 sources for
which Chandra archival data are available. Most of these sources have been
already published. Here we provide a uniform re-analysis and present nuclear
X-ray fluxes and X-ray emission associated with radio jet knots and hotspots
using both publicly available radio images and new radio images that have been
constructed from data available in the VLA archive. For about 1/3 of the
sources in the selected sample a comparison between the Chandra and the radio
observations was not reported in the literature: we find X-ray detections of 2
new radio jet knots and 17 hotspots. We also report the X-ray detection of
extended emission from the intergalactic medium of 15 galaxy clusters, two of
which were most likely unknown previously.
