interchangeable Myford beds

[KundrusParticipant @olafkundrus1]

Is the lathe bed from a 1967 super 7 interchangeable with a 1975 ML 7?

Thanks

Should be !

Assume you are in Scandinavia somewhere?

Have a look at https://www.lathes.co.uk/. Scroll down to the “lathes” list and click on Myford for all sorts of history lessons. In 1973 the S7 bed was modified from machine K111727 to accomadate the power cross feed version which involved modifying the cross slide guides. This did not alter the bed dimensions but somehow altered the relationship between cross slide (clamp nut alignment) and lead screw. I cannot recall better detail.

Assuming you know the checks you need to do for wear, don’t buy unseen or checked out somehow.

You might check the spare parts diagrams on the Myford website and see if the part numbers are the same.

In May, 1972, from serial No K107657, the existing carriage was converted from the narrow guide to the wide guide principle. On the earlier machines the saddle located across the front two shears and on later models across the full width of the bed, the 5/8” diameter leadscrew and die cast apron were retained.Until Machine K108718 slotted BA screws and locknuts were used for the gib-strip adjustment ,but after that easier-to-set self-locking 5mm pitch hexagon-socket screws were used instead.From serial No K108718, the cross slides were fitted with 5mm pitch self locking adjusting screws.

Super 7 Apron now used with 4 instead of 5 securing screwsApril 1973, saw the introduction of the new bed and saddle casting (Bradley) from serial No K111727. The re-design was necessary to accommodate the power cross feed apron on the Super 7 lathe.  At the same time the specification of the ML7 was upgraded to incorporate the ¾” diameter leadscrew and cast iron apron as used on the pre-power cross feed Super 7’s

So the 1975 ML has the same apron as the 1967 Super 7 .

It has the 3/4 leadscrew like the 1967 Super 7

It uses the same saddle as the1967 Super 7 but has already the wide guide principel, no mod necessary.

The 1975 ML has hardened bed ways, the 1967 has not.

My idea is to integrate the bed , apron and saddle from the 1975 in to the Super 7 from 1967.

This way I get the best out of both machines, I do not need to buy the part. I get them.
