Worn center bearings on Westinghouse D2EG andD3EG air compressors are built up by the weldingprocess. The babbitt is first taken out and the bearingfilled in with metal to a depth of V2 in. or % in., afterwhich the compressor case is placed in a drill press andthe bearing housing bored out and fitted with a brassbearing. Worn journal side-plate bearings are alsobuilt up. The bearing way is filled and the journal is.

The maintenanceon the door-operating handles on a number of the carswas materially reduced by welding. These handles werepreviously riveted or held to the vertical rods with set screws, and trouble was constantly experienced by theirbreaking off. To remedy this they were permanentlyv/elded in position. The oxy-acetylene cutting frame was used to goodadvantage in a case in which it became necessary inthe reconstruction of an electric locomotive to cut thedoor in the operating cab 5 in. wider. This meant thecutting of the }4-in. steel side sheet through a verticaldistance of 6 ft., and it was done readily with theacetylene flame, whereas it would have been a consider-able problem to accomplish cutting by mechanicalmeans.
