A History Of The ML7
The ML7 lathe was launched in August 1946, the basic bench lathe, retailing at £34.00. The ML7 was so successful that it saw the immediate demise of its' predecessors, the ML2 and the ML4. The Myford 'M' type, a Myford conversion of the Drummond 'M' type, cost £42.00 and production of this was discontinued in 1949. Over its 33 years production run, the ML7 stood the test of time remarkably well. Whilst there were numerous minor changes, the number of major design changes were very few and these are listed below;

In July 1969, commencing with serial number K90494, a cast lug was incorporated into the headstock. The lug is situated just behind the spindle nose and its initial purpose was to act as an anchor point for the optional lever operated collet attachment. In later years the same point would be used as a pivot point for the chuck guard.

In May 1972, from serial number K107657, the existing carriage was converted from the narrow guide to the wide guide principle. On earlier machines, the saddle located across the two front shears and on later models across the full width of the bed, the 5/8" diameter leadscrew and die cast apron were retained.

From serial number K108718, the cross slides were fitted with 5mm pitch self-locking adjusting screws.

April 1973 saw the introduction of the new bed from serial number K111727. The re-design was necessary to accomodate the power cross feed apron on the Super 7 lathe. At the same time the specification of the ML7 was upgraded to incorporate the 3/4" diameter leadscrew and cast iron apron as used on the pre-power cross feed Super 7s.

The last machine, serial number K140848, left the fitting lines on the 31st January 1979.

It should be noted that long bed ML7 lathes were always fitted with the 3/4" diameter leadscrews and the saddles, cross slides and top slides were the same as used on the pre-power cross feed Super 7 lathes.

PLEASE NOTE: On earlier machines (up to serial number K111727), the serial number can be found on the rear shear of the lathe bed, at the tailstock end of the machine. On later machines (after K111727) this will be found on the front of the lathe bed, to the left hand side of the rack.
