Myford ML7 using Super 7 parts

I’ve read statements in various places in regard to the Myford ML7 long bed version e.g.

“Parts from Super 7 as standard, leadscrew, apron, saddle, cross and top slides.”

“The cross slide and top slides replaced with the correct Super 7 versions.”

I have a long bed version ML7 and was wondering if mine was therefore either not standard or sometime down the track someone replaced these parts with standard ML7 parts? Are there any expert Myford people out there to answer this? I’m more just wondering out of interest sake.

I tried contacting the ‘new’ Myford but they say the weren’t given any records on taking over. The serial on my bed dates it to mid 60s.

Have a look at pages 194 – 196 iof "Myford Series 7 manual" by Ian Bradley that detail the design changes from ML7 to Super7

I’ve got my manual on order actually, just waiting for it to arrive.

One of the articles in the latest MEW has a good rundown on some of the differences between ML7 and Super 7. I think it was the one on modding the tailstock.

differences between ML7 and Super 7.

I'm more specifically after the parts of the Super 7 that were supposedly used on the ML7 long bed rather than the differences between the standard ML7 and Super 7. From what I've read it might have been standard practice to use some of the Super 7 parts, however, mine hasn't got these 'features'.

I do not think that apart from the leadscrew and rack there differences are between the standard and longbed versions. I know the holes in of the longbed rack does not match that of the standard bed because I stil have a longbed rack waiting to fit onto my standard bed S7 to get the maximum travel out of saddle when all limits are removed.

I think some folk forget there was a ML7-R, and this had some features, notably cross-slide and topslide, from the Super 7. Possibly tailstock as well.

Intended as an improvement on the ML7, but not as expensive as the Super 7.

[Brian WoodParticipant @brianwood45127]

The ML7-R has the Super 7 headstock, motor and countershaft platform, tailstock and 7/8 inch diameter leadscrew.

The apron, cross-slide and top slide are all to ML-7 pattern. It is a perfectly reasonable hybrid, but there is no possibility of power cross feed except by one of the 'ad-on' kits that can be fitted just behind the ball ended operating handle

I don't think that is correct based on what I have read. The ML7R had the 'standard ML7' saddle, cross slide and top slide.

Some of the locations where I was reading about the long bed ML7 actually and the use of Super 7 parts.

I guess in the end I'll never know for certain whether the parts with my lathe were original without the order form / invoice!
