You willalso note that we have cored in thecrosshead keyway, and by changingthese cores to right and left the onepattern does for both sides. We getvery good results from the core work,and do what little finishing that is nec-essary by filing. You can readily seethat the machine work comprises bor-ing out of the piston rod fit and boring uable journal on burning natural gas,which was a paper read by Mr. Whit-ham before the American Society ofMechanical Engineers, and being inter-ested
