Myford Super7

I have recently purchased a Myford Super7, the number stamped on the rear of the bed is SK83292 and it is painted Myford green, can anyone tell me if it is possible to obtain any history on the machine ? Thanks . Ken.

Myford used to hold the records for their machines, and were able to tell me when mine was made, the original spec, who  inspected it and who supplied it.

I would assume that the new Myford company took over these records, you could try contacting them via the advert on the right of this page.

Hope this helps.

If you go on the Myford site it will tell you all about the S7 and what year each serial No.

Hi

Going from a list I downloaded from the "Original" Myford company site before it was closed, the nearest numbers listed are - 81275 = 1967. 82989 = 1968. 85000 = 1969 approx. 90125 = 1969.

You say that your number is stamped on the rear of the bed - normally they are numbered on the front of the bed on the headstock end, but I do know that some (mine included) were stamped on the rear at the tailstock end.

I contacted Myford before their demise and they could not offer any reason why the numbers were on the back other than "human error"

Hope this helps

Factory colour changed from grey to green at SK142981 in April 1977 (from Myford's own website, downloaded October 2010).

Ian Bradley in his "Myford Series 7 Manual" says that serial numbers were originally stamped on the rear shear at the tailstock end and subsequently moved to the front shear at the headstock end, but gives no date when this occurred. (It was before SK122038.....).

Much more confusion - If the colour was changed from grey to green on/about SK142981, then Kenneth Deighton has a product that is before this date - His number is SK83292 which may indicate that it is a "Repaint" which could have been part of a factory rebuild.

My own Lathe is a Super7 - Grey - Date of supply (to the original owners) Sept 1971. Number SK 99535 stamped on the rear at the tailstock end.

As KD's Lathe is prior to my numbers then one could be confident in saying that it his lathe should/would have been produced in 1968/69 and as it is before Myford changed the colours should be Grey (Unless a repaint!!)

Can any one else (possably ex Myford) give more info.

Sorry to re-open this topic but I am a little confused over the Serial Number of my own Super 7 Lathe. The number is stamped at the tailstock end, like most others, and it is SK 52518, which seems to be much earlier than those on this Forum beginning with an 8! It's the standard Super 7, in grey with a fitted gearbox.

Can anyone explain this very low number please? Thanks. Geoff

I removed this as it was purely a repeat of my previous post on this thread, except for a Myford link.

I think these days if we say "I contacted Myford" we need to qualify this with which Myford we mean, the original company at Beeston, or the new owners of the name, RDG.

Myford(Beeston) should have known that the serial numbers were on the rear at the tailstock end for years, and were changed to the front, headstock end later, and a number on the rear is not a mistake. It was common knowledge. The handbook supplied with the lathe indicated by a little drawing that the number was at the rear under the tailstock, so it could be quoted when ordering spares.  There is an image in my album, but I still can't load it into the posting due to technical fault.

I have two S7Bs at present, a Mk1 no SK 1831, which left the factory on 10 May 1954 (when I was eleven, and it's wearing better than me), and a Mk2 no SK 78287 which left the factory on 19 December 1966, no doubt as somebody's Christmas present, which ties in with HomeUse dates above

Those dates were verified by the staff at Myford(Beeston)

Any help?

Geoff - are you sure your number starts with a 5, and not a badly stamped 8? I find them difficult to read upside down and leaning over the tailstock!

Hi Phil,

Well, yes it is a 5 and not an 8. I checked it again after I saw the serial numbers with 8 for the reason you suggest! As my S7 has cup oilers I assumed it was not a very early model.

What has prompted me to ask about the numbers is that I need a new headstock drive belt, having removed both spindles. In his Myford Manual, Ian Bradley states on page 10 that the drive belt should be 23 inch inside length. On another Forum I found 33.5 inches quoted, which I bought, and of course is totally wrong. The existing belt is about 28.5 inches (and this has no doubt stretched over the years (30 in my ownership). And I've been told by an 'auction site' supplier that the correct belt is an 'A' 29.5 belt. I'm tempted to purchase a 28.5 belt because, otherwise, the motor-to-countershaft belt will be too small!

Any thoughts please!

Geoff

you could just go here

Probably the best bet, buy both replacement belts. Thanks for the link.

Geoffrey

My advice to you is to purchase link belts for your Super 7. - I bought mine ( just the motor - countershaft belt so far as the countershaft to mandrel belt is OK) from HERE but they are available from lots of places. It transformed the running of my S7. It used to vibrate frighteningly at he higher speeds - now it is quiet and super smooth throughout the range. What's more, when the time comes to replace the other belt there is no need to dismantle the headstock.

Thank you Norman,

I've read about the link belts, but as I have the Headstock spindle partially withdrawn now I have just ordered both belts from Lathe Spares.

Thanks for all the replies so far.

Geoff

I was always told that the link type belts awear the pulley more due to the metal content of the belt is this true or not as they are as alresdy discussed a lot easier to fit than a standard v beltGeoffre

Hi Geoff

I don't know about the link belts with a metal fastener but I would have thought that the fastener would not be in contact with the metal of the pulley - if it was then sure wear would occur. ( I accept too that the link I posted does show metal joiners but that was not the type supplied!)

To clarify the matter here are a couple if pics of my belt - no sign of wear as you will see.

Here you can see that the joining tabs are part of the belt material.

Studying this photo It does look as if I should do a bit of a clean up !

Good luck - I'm very pleased with my link belt!

Norman
