An obvious development of the original machine, the Haighton "Cadet" was very well built, almost a large lathe in miniature, with an outstanding specification and very careful attention to detail. The bed, held down with four bolts at the headstock end and two at the tailstock, was fitted to a slightly modified and rather better-finished aluminium baseplate with rounded edges. Later models changed to a much-improved cast-iron plate, the increased rigidity of which played a large part in the lathe's ability to take surprisingly deep cuts while maintaining accuracy. As a reflection of its quality, and comprehensive specification, the price of a complete, motorised the Cadet in the late 1950s was £44 : 15s : 0d, only £7 : 2s : 6d less (25%) than asked for the 3.5" x 20" Myford ML7. However, despite the steep price, in 1953 Haighton were able to run a series of advertisements in Model Engineer Magazine proclaiming Now over 500 satisfied users. Assuming this to be accurate, it was a reasonable achievement, meaning sales averaging 3 per week and bringing in a steady if unspectacular income for the company.
A proper backgear assembly and full screwcutting were fitted as standard and the 3/4" x 12 t.p.i. spindle fitted with a No. 1 Morse taper nose - where an inadequate No. 0 might have been expected. Simple, split bronze bearings were used and 12 speeds provided (including backgear) from 25 to 1800 rpm. As before, the 6-speed countershaft assembly was bolted to the frame and used proper (if miniature) 3/8" (8 mm) V-belts to transmit power from the full-size (and hence heavy and reliable) Brook Gryphon single-phase motor (today these belts, if unavailable, are easily replaced by 8 mm round ones, heat-welded to the right length). In place of tumble reverse (which is difficult to engineer satisfactorily on small lathes) a dog clutch was fitted to the headstock-end of the 0.5-inch diameter, Acme-form leadscrew. Because the leadscrew nut was "full", and could not be disengaged from the carriage, the clutch was an essential fitting - and also eliminated the chance of making errors when re-engaging the drive during screwcutting. Of 30 DP, the changewheels were arranged in a rather unusual way with, picking up from the headstock-mounted gear, a pair of gears on a fixed stud (only pre-set clusters, permanently riveted together, could be used) a situation that made selection of gear sets awkward. The drive then passed to an ordinary swing-bracket arrangement upon which gears could be changed. Although not confirmed, it would appear that the lathe was supplied with changewheels sufficient only to provide a single rate of fine feed, the standard arrangement being: 24t/60t, 30/60 and 20/80 to give a 20 : 1 reduction and a feed rate of 0.005 per rev. As every change of pitch required a different gear on the end of the leadscrew, the owner was faced with the expense (if a full screwcutting range was needed) of buying an extra 15 gears. The situation was worsened by the design of the leadscrew end - its machined boss required every gear to have a matching section on its rear face.

On the Grindturn only a single, swivelling top slide had been fitted (though with a 4-way toolpost as standard) but Haighton improved matters considerably by including a proper and very well made compound slide assembly.  Although the top slide could be swivelled through 360°, and fixed in one of two positions on the cross slide (each location complete with degree marks) the makers did not, oddly, think fit to include a T-slotted slide -  nor to offer one as an extra. However, they did eventually list a beautiful swivelling milling slide, an item so rare that the writer has only ever seen one example. Another Haighton enhancement was the fitting of clearly engraved, zeroing micrometer dials to the 1/4" x 26 t.p.i. (standard BSF specification) feedscrews (the Grindturn had had non) and proper "balanced" handles in steel. In later years the rather fine spoked tailstock handwheel was replaced by a plain, full-circle type--though this may have occurred simultaneously with the change to Zamak micrometer dials when manufacture passed into the hand of Cleveland Guest. A 4-way toolpost continued to be included as part of the standard equipment (a special and expensive quick-set tool holder from Burnerd was also available) along with full enclosure for the changewheels - and a semi enclosure for the headstock drive belt. 
Of remarkable weight and strength, the No. 1 Morse taper tailstock could be set over for the turning of slight tapers and had an unusually large handwheel - the latter an item often neglected on miniature lathes.
Although described as, "Completely self-contained and portable" the large base-plate and full-size electric motor meant that the all-up weight (even with the aluminium support) approached  42 lbs and it was certainly not as easy as the makers claimed to: "Turn your kitchen table into a workshop". When fitted to the 70 lb cast-iron base it was most definitely not easy to move around, especially when the large Gryphon motor was included. Doubtless Er in do'u'ers (or, as our much more perceptive  American friends would say,  SWMBO) would also have had a thing or two to say about the matter, especially if asked to help carry it back to its storage in't' 'cole'ole.
Very early models seem to have been finished in either a very ordinary plain grey or, as an amazing contrast, in a remarkable "craquellee" black-and-white finish not unlike that given to the quite different German Hommel. Later machines changed to a beautiful crackle-black paint (used until the 1950s to indicate mechanical items of better-than-usual quality) and then to a black finish with white speckles.
One crackle-black example of the Cadet that the writer found several years ago was still resplendent in its original finish (which had lasted remarkably well) and ran almost silently, with the heavy bed plate adding such enormous stiffness that it was, as a consequence, capable of taking extraordinarily heavy cuts for so small a machine. If you find a Grindturn or Cadet don't be tempted to take it off the mounting foot, the lathe really will work much better in its original form.

The drive then passed to an ordinary swing bracket arrangement upon which gears could be changed. The silver flecks in the black paint can just be made out.

When Cleveland Guest took over manufacture the introduction of nasty, die-cast Zamak dials that lacked numbered graduations did nothing to improve what had always been an otherwise superb little lathe.
