Atlas Vertical Milling Attachment
of unknown manufacture

A Handbook and Parts List is available for the Atlas/Craftsman Miller

Devoid of any maker's marking, this "unknown" vertical attachment was fitted with step-up gearing that approximately doubled the speed to give a range suitable to run small-diameter milling cutters successfully. Drive came from a horizontal shaft that fitted into the No. 2 Morse taper end of the miller's horizontal spindle. A pair of bevel gears turned the drive through 90-degrees to rotate a spindle fitted with a simple draw-bar retained collet holder - the holder and its collets looking remarkably like those used decades later on the East German Hobbymat BF Series vertical miller. The unit was given sufficient forward reach to enable reasonably-sized jobs to be machined, although its horizontal stem was perhaps unnecessarily light in construction. If any reader has one of these attachments the writer would be interested to hear from you.



This "unknown" vertical attachment was a simple but well-engineered device that turned the Atlas horizontal miller into a much more useful and versatile machine tool.

The unit was given sufficient forward reach to allow reasonably-sized jobs to be machined - though its horizontal stem was rather lightly constructed



The simple collet holder bore an uncanny resemblance to that used decades later on the East German  Hobbymat BF Series vertical miller

Inside the milling attachments casing : set-up gearing produced the faster speeds necessary when using small-diameter cutters

Initial drive was by a spur gear carried on a No. 2 Morse taper shaft socketed into the miller's horizontal drive shaft
