On the few examples to make it to Europe these speeds were somewhat reduced by the 50 Hz, 1425 r.p.m. The spindle carried a 4-step pulley, driven by 2-step pulleys on motor and countershaft - a combination that gave a remarkably wide range of 16 speeds between approximately r.p.m. nose could this have a been a sort-run batch for some specific task, possibly production and originally fitted with a capstan unit ?ĭrive on all models was by proper, full-size V-belts, Z-section (about 0.4" or 10 mm across the top) on both motor and headstock drives.

However, one example of the lathe, Serial Number 1006, has been found with a most unusual fitting, a spindle with a 1.25" x 14 t.p.i. thread (later 1" x 10 t.p.i.), was fitted with a 60-hole indexing ring on the face of the backgear bullwheel and ran in Timken taper-roller bearings with part numbers: 07079 left bearing, 07100 right bearing and 07196 for the two bearing cups. 2 Morse taper, 17/32" bore headstock spindle had a 1" x 8 t.p.i. However, despite its modest price, it was offered with a wide range of useful accessories and enjoyed a number of desirable features: the No. Like all Atlas lathes, the 6-inch was mass produced, with costs kept down by the use of parts in Zamak - a pressure die-cast metal.

2 countershaft with the swing-head hanging down backwards and the V belt passing between the uprights.Īs few appear on the used market, the number of early versions produced must have been limited and later machines (commonly seen as Craftsman Series 101.73**) are much more frequently encountered. However, it was made for one year only before being replaced by the much better specified 101.07301-as listed in the post 1938 catalogs shown hereĪtlas 6" x 18" (3" centre height) - 1941 version with the taller, Mk. spindle thread, a headstock that lacked backearing and a countershaft unit and belt-tensioning arrangements of a very elementary, lightweight design, was sold at the very competitive price of $42. This initial Craftsman model, which carried an inadequate 3/4" x 16 t.p.i. Enormously popular in America - it was affordable and with a specification that allowed it to undertake the majority of jobs likely to be encountered in a home workshop - its likely that the lathe made its first appearance not as an Atlas but badged for the mail-order company Sears,Roebuck under their Craftsman identification tab as the 101.07300. Styled to closely resemble its larger brother, the " 10-inch", the Atlas 'Model 618' 6" x 18" (3.5" centre height) backgeared and screwcutting lathe was in production from 1936 until 1974 and then, in Mk. 1 PhotographsĪtlas 9, 10 & 12-inch Lathes Atlas Milling Machine Atlas ShaperĪ complete Data Pack is available for the Atlas 6-inch lathe

However, whilst the former would be light enough to lift off the bench yourself, the latter would need an engine crane and a trailer to get home.Email: t Machine Tool Archive Machine-tools Sal e & Wanted For most home machinists and small repair workshops something between a 3” x 15” and 6” x 30” machine will be ideal. How big to go? Well, bigger is not necessarily better - and moving larger machines can be an expensive proposition. Some American makers, South Bend for example, also quoted the bed length as part of the specification however, this is an irrelevant figure - it neither tells you the longest piece of material that can be turned, nor the length of the lathe. With a “bigger-and-better” attitude the Americans of course quote the largest diameter of a workpiece that can be turned clear over the bed - termed the "swing" - and so, in the example above, the American sizing would be 8" x 24". In this case the centre height is 4" and the distance between centres (the maximum length of material the lathe can accommodate) 24". The "English" method of sizing a lathe is to quote the centre height - or "throw" - the distance from the centre of the chuck to the nearest point on the bed.
When you see a lathe branded as, for example, 4" x 24" what does this mean?
