Turning a leadscrew in a specially-adapted Hendey lathe. It was not unusual for machine-tool companies to buy leadscrews in from specialist manufacturers, but Hendey preferred to make their own.
An alternative method of leadscrew production - thread milling.
Rough turning the nose of an alloy-steel forging - the first stage in the machining of a headstock spindle. The lathe is a Hendey "No. 3 Hi-Speed Production".

Sizing holes in Hendey collets. These were made "in works" instead of being bought-in from the usual specialist suppliers. One wonders at the economy of such a decision, especially when it was admitted that production only ran to "thousands" per year.
Another stage in the decidedly labour-intensive production of collets - milling the slots using a twin-holder jig.
Even some tooling was made in-house: here a sub-headstock (to get very low speeds) is used with a relieving attachment to manufacture a milling-cutter
Dave Curtis, a "veteran past master in tool making" using the sub-headstock and relieving attachment to manufacture a broach.
View of the planing, heavy milling and boring floor. Judging by the number of un-machined castings stacked up behind the tooling rack in the foreground, the shop was working flat out
