Variable Speed Controls and Motors for lathes and milling machines, including; Myford ML7, Myford Super 7, Boxford, Raglan, Union Graduate and Jubilee Wood turning.
Thanks to all for the suggestions for a Graduate manual. I have been looking on the web and have come up with this link which gives information on the Variturn version of the lathe, but still very useful exploded diagrams. It's also available on but in a not-so-convenient format. Mystic Island Cribbage. Another useful site is:- which gives a load of sections including a Graduate manual with details on their sanding table and lampstand making attachments, also a 4 page article by Fred Holden on thread chasing, a 32 page article on tools and jigs and loads more. When you first visit the site it looks like 2 pages, but then a 3rd appears, etc and it goes on for over 20 pages that I have seen and there's probably more (I got fed up looking). Mod Edit:- Link removed, I hope this may be of use to turning colleagues.
Harrison Jubilee Union, Sagar & Cooksley Lathes email: Harrison 'Jubilee' & 'Union' (and Sagar & Cooksley) Woodturning Lathes A handbook and catalogue Set for the Jubilee The first Jubilee as shown in the 1939/1940 catalogue Introduced in the late 1930s and shown in catalogues for that era (and not, as widely supposed, for the 1948 Golden Jubilee of the Harrison company ) the 'Union' Jubilee wood-turning lathe had a 5-inch centre height and was available in versions offering 30', 42' and later 54' between centres. For a short time during the mid-1950s the lathe could also be had in what was described by the makers as a 'heavy-duty' version with the centre height increased to 6 inches, the spindle fitted with a 1.5' x 6 t.p.i.

Selling for £27: 10s: 0d in 1939 (with an extra foot of bed costing and additional £1) it was designed to comply with factory regulations for guarded drives and described in the pre-WW2 brochure as being: intended for technical school use. Indeed, the lathe did subsequently proved enormously popular - not only with professional wood-turners, but also with educational and training establishments from its introduction until 1965 - by which time the superior, much heavier 'Graduate' lathe had been on sale for six years. During its last two years of production the Jubilee was listed at £96: 0s; 0d, with the Graduate only some £16 more expensive - at such a small difference in cost one wonders how long the old Jubilee stock took to clear. A 27-year production run must have seen many thousands of the lathes sold and today examples are widely available at bargain prices.
Of heavy construction, the lathe used cast-iron bed rails tenoned and dowelled into the face of a headstock plinth constructed from very heavy-gauge, welded steel plate. The 3/8' bore, No. 1 Morse taper headstock spindle carried, a 1' x 10 t.p.i thread on both ends (though be warned, some have been found with a 1' x 8.t.p.i.) and ran in simple ball races. The bearings were lubricated by screw-down caps which, if turned once each day, required filling weekly. It was powered through its 4 speeds of 425, 790, 1330 and 2250 rpm by either a 0.5 hp or 0.75 hp Crompton-Parkinson motor mounted on a vertically-adjustable plate within the cabinet leg - where the moving parts were (almost) safely hidden from the curious fingers of schoolboys and apprentices.
