The completely-different apron of the Joinville. Instead of power being taken to both longitudinal and cross travel this clone had it restricted to the cross feed only - with the clasp nuts providing both the screwcutting and sliding feeds. Although this was a perfectly satisfactory arrangement the original South Bend mechanism was superior in that it gave a geared-down and hence slower rate of sliding feed than could be obtained by use of changewheels and leadscrew.

View of the headstock showing the conventional backgears and the serrated nuts to retain the large adjustable bronze bearings with their tapered outsides. The bearing oilers are non-standard.
