Listed for many years as the Model SO, the Deckel tool & Cutter grinder has been widely cloned (many examples are now made in China). In the UK the best-known copy was Alexander, who produced a version to the same very high standard of the original (as well as a simplified version intended mainly for sharpening the D-bit cutters of the firm's well-known engraving machines). Taking a grinding wheel 4" in diameter by 2" wide with a 25/32" bore, the Deckel/Alexander SO was fitted with a 3-phase, 0.25 hp, 2800 rpm motor with the wheel running at around 5000 r.p.m. The cutter to be sharpened was secured in, on early models, an unknown type of collet with a 16 mm shank that had a maximum capacity of 1/2" (12 mm). Later (and by far the more common type) used what the makers listed as a Schaublin Type 20 with a 5/8" capacity (17 mm). Hence, as the early collets are now unobtainable (though they can be specially made), before buying one of these machines (or ordering new collets) do check what the situation is, An early model without a complete set of collets, or with ones that are worn, will be very expensive to rectify - and should be far cheaper to buy than one fully equipped. A further problem arises with regard to the later collets sold around the world as the Type U2 and often listed as being: "suitable for Alexander and Deckel grinders". Owners report that these fit the Alexander version, but not the Deckel - or the threads, at least, are different. If you have direct experience of this situation and any difficulties it has caused, the writer would be pleased to hear from you.Collets were mounted in a housing (the index carrier) on top of a short-travel slide fitted with a vernier scale. The slide was fastened to the end of a swan-necked arm, mounted on a double-swivel base which itself was carried on a boss that could be slid along and rotated around a horizontal bar. In addition the bar was finely adjustable "left and right" by a micrometer screw with its dial and handwheel on the left-hand face of the machine.In the 1970s Deckel introduced the Model S0E (to run alongside the S0) an improved design but one that was operated in exactly the same way. Besides modern, sleeker line, modifications included: a built-in motor with an adjustable dust exhaust hood (it could be repositioned to allow wheel dressing); more complete guarding of the wheel; an axially moveable wheel spindle (under the control of a micrometer dial) that allowed precise wheel dressing and a telescopic, stub-mounted horizontal support bar - an arrangement which, with the removal of the end-support bracket, afforded much greater clearance around the job.One option available for the SOE was a bolt-on Optical Measuring Projector. This enabled the operator to view the profile of a cutter mounted in the holder and assess, from a scale, the various dimensions and angles. The unit consisted of a housing to hold the optical system and a ground glass reticule on which rested a second reticule that could be rotated through 90. The measuring projector could only be used on the index head carrier for which it was supplied - the image plane of the ground glass being adjusted so that the axis of the reticule coincided with the tilting axis of the index head and the distance from the object plane corresponded correctly to the magnification ratio.
