J.Santaella Lathe - France
Another French lathe of unusual design and execution, the Santaella tour would have had a centre height of around 80 mm and accepted some 300 mm between centres. Although the writer has no access to sales literature about the lathe, he would guess that, as there is no leadscrew (and no easy access to any changewheel drive) that it was of the very simple, plain-turning type. However, this lathe has an almost certainly unique feature, its tailstock that mounted, on the centre line, a 3-jaw chuck (which jaws that carried rollers to support between-centres work) and, above it, a slide rest mounted like that on the ram of a shaping machine. The "ram" appears to have been driven by both a feed screw and, from the position of a long lever emerging from above the tailstock casting, by lever-feed as well. The slide's use? Presumably for slotting - an odd, single-use attachment for such a small lathe. However, as a 3-jaw is fitted below it, perhaps the machine was intended for some unknown, special purpose.
On the left of the machine and forming part of the headstock assembly, a large sheet metal cover must have concealed a 2-speed, AC motor that was either flange-mounted to the headstock spindle, or even performing that function directly.
Appearing to be fitted with a single swivelling tool slide could the carriage have been moved along the bed by a rack protruding below the front bed rail?
Other twin-bar bed French lathes included the very different Codima and Ermo.
