The Stark No.3 lathe was also available fitted for production processes, usually with a 6-station turret and a cut-off (sometimes called a forming) slide. The rest of the lathe was absolutely standard but, in order to maximise the lathe's output, it was not unusual to see them fitted with a much more complex and expensive countershaft arrangement (which gave extra speeds and sometimes reverse) than those used for between centres and collet work.
Although it was not unusual to find early bed-mounted turrets with a mechanism which both drew back the slide and at the same time automatically rotated and indexed into position the 6-tool head, it was rarer for them to be fitted with six independent depth stops to control the feed of each tool. The unit illustrated on the Stark is an early version, with only a single stop, which would have meant a great deal more setting up time, and considerable difficulty in making small adjustments as the work progressed. This page has a picture of the later turret units with multiple depth stops.
Several makers of precision lathes produced "three-bearing" headstock models which were designed expressly for production use - usually in factories specialising in smaller components; the Stark example is illustrated on this page.
