The carriage of the Cub was heavily built with a double-wall apron, exceptionally large micrometer zeroing dials for the period, taper gib strips on both top and cross slides and a completely protected cross-feed screw. Unfortunately the cross slide was of the short type (with a cast cover at the back to cover the end of the feed-screw) and, whilst the power sliding and surfacing feeds were conveniently selected by flicking a centrally-mounted lever left and right their engagement and release was through a screw-in-and-out knob - with no method of reliably and instantly disconnecting the feed.

Twin V-belt drive and rather fine-pitch changewheels. Note the small diameter of the headstock spindle.
