Also known as the "Lesto" the Scinta 110 mm (45/16") centre height lathe was made in Switzerland by Scintilla S.A. with parts and servicing surviving in the hands of KMD AG Deitingen. The arrangement survived until March 2007 when the company was declared bankrupt and (instead of being sold to a local enthusiast) the remaining spares and accessories were scrapped (photographs at the bottom of the page).
Obviously a machine of high quality, tested to Schlesinger standards the lathe was built on a two-bar bed with an optional cast-iron under-tray (complete with motor-platform mounting lugs) that was designed to add a significant degree of stiffness to the structure. A choice of two bed lengths was offered (at the same price): 620 mm and 870 mm (24.4" and 34.3") - which gave distances between the No. 1 Morse centres of 400 mm and 650 mm (15.7" and 25.6") respectively. However, at extra cost any length of bed could be ordered - up to a maximum of 1500 mm - and, if the customer desired, the factory would supply the bed rails with a hard-wearing chrome-plated finish. The lathe was offered in a two forms - as a basic unit for wood and hand-turning (Models GD100 short-bed, GD102 long bed) or as the more complete Models GD1123 short and GD1124 long to various specifications with screwcutting by changewheels driven through a tumble-reverse mechanism. The standard changewheel set consisted of just five gears able to produce one (automatically-disengaged) sliding feed of 0.002" (0.05 mm) per revolution of the spindle. Twelve extra gears: 40, 48, 50, 55, 60, 63, 64, 70, 72, 75, 80 and 90 were available to produce a wide range of metric threads - with a 127 translation gear (as an extra) to generate English pitches.
Little equipment was supplied as standard, the GD100/2 arriving with only a driving plate, a 3-pronged centre for wood turning, a long hand T-rest and support, two No. 1 Morse centres, a single collet with a No. 1 Morse taper, the spindle-driving pulley complete with a ring of indexing holes, the indexing plunger - and a spanner. One interesting accessory was an outboard "bowl-turning" faceplate, mounted on the face of a special, single-speed, spindle-drive pulley. The customer who ordered the metal-turning GD1123/4 received, in addition, a cast-iron base plate (either the GDZ511 - or the longer GDZ514) a 3-jaw chuck, a flat drilling pad on a No. 1 Morse taper, a screwcutting leadscrew, a tumble-reverse assembly (engineered in a most unusual way), a most handy automatic-disengagement trip for the carriage feed, five changewheels, a compound slide rest and a built-in reversing switch. The factory would also construct machines to individual specifications, with parts drawn from the options' list.
Driven by a simple, overhung 4-step V-pulley directly from the motor, the 35/64" (14 mm) bore spindle and headstock assembly looked not unlike that used on the American Delta wood-turning lathe. Surprisingly, no form of speed-reducing countershaft was available; instead, Scintilla offered an alternative pulley for the motor which contained a beautifully-engineered 16 : 1 epicyclic reduction-ratio gearbox - this accessory both doubled the number of speeds (to eight) whilst giving a sufficiently low speed for screwcutting and large-diameter turning.
Besides the usual range of accessories offered with a precision lathe - chucks, collets and steadies, etc. - several more unusual items were listed including a jigsaw, wood planer, tilting saw bench, sheet-metal "nibbler", flexible drive unit- and a finely-made spherical-turning tool.
Sadly, in the early years of the 21st century, all the spare parts were sold to a scrap dealer - despite a better offer from an enthusiast keen to keep the brand going.
