Taper turning unit with fine-screw adjustment of the setting

Taper-turning unit - component parts

Neat detailing with flat-faced, pin-drive nuts used to secure the swing bracket and adjustment unit.

Whilst the degree marks were punched (or rolled) with a single tool the digits and letters were stamped individually by hand

The full collet set in place on its circular, swing-out holder

Non-damaging wooden pins were used to locate the collets

Traditional precision lathe tailstock with a long travel spindle fully supported within the casting no matter what its position

Probably unnecessary on a lathe of this size, but the tailstock was secured to the bed by two clamp plates

Component parts of the tailstock

Not every maker provided such a chart to enable non-gearbox pitches to be generated

Even in 1950 the lathe was considered worthy of a comprehensive rebuilt by a long-established machine-tool company.

….and finally, how do you drive it. Like many other lathe-owing, motorcycle-enthusiast owners, you employ a surplus (Norton) 4-speed gearbox
