Unusual-design of changewheel bracket on the end of the screwcutting gearbox
A "gate-change" lever, protected by a flip-up guard, selected three rates of sliding and surfacing feeds
Comprehensive screwcutting gearbox
Instantly recognisable as a design from the early 20th century, the apron carried twin friction clutches to engage the standard-fit power sliding and surfacing feeds. A useful addition was a large dial to show carriage travel.
The useful zeroing carriage-travel dial
Compound slide rest fully assembled
Cross-slide with rear extension to pick up the taper-turning unit and front and back stops installed
The top slide nut was generously proportioned and twice the length of those normally fitted to this size of lathe
Top slide completely dismantled and showing the quick-release mechanism that required just one squared-headed bolt to be slackened before the slide could be rotated
For its era the cross and top-slide micrometers dials were remarkably clear and even of a reasonable size
Above and below: small but clear Micrometer dials. These were locked by a knurled-edge ring that caused no alteration in the setting as it was tightened. One example of the lathe (No. 126) has been found fitted with a very large diameter dial--though this might have been an owner's modification
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
