Super 7 questions

[Rod RenshawParticipant @rodrenshaw28584]

Re the oil cups for the countershaft bearings.

My 1970s vintage Super 7 handbook has a rather "For Industrial use" feel about it. It says, on the fold out page, "Replenish oil-cups daily" but on the following page, in the text, it says "The hardened steel countershaft runs in oil impregnated bronze bearings which are located in the swing head. Oil cups are provided for occasional lubrication."

I have tended to follow the later instruction, adding a few drops of nuto each time I came to use the lathe after a period of not using it, so rather like Martin's regime. I am still using the original shaft and bearings after 40 years so I don't worry too much about it.

I remember reading a number of years ago that Myford changed at least some of the 1/4" bsf cap screws to M6 due to the old Super 7's used 2 sizes of heads, large and small. The large head 1/4" Cap screws became unobtainable and the M6 Cap screw is between the 2 bsf head sizes. The large head we used to attach the carriage to the apron.

I would assume that Myford stopped all 1/4" bsf at that time but not sure when this occured. Check the manual if you have one, else get one.

Thanks, everybody for that information. I feel very much relieved about that oil-thirsty bushing.

On the topic of oil guns, yes, I have one of the Myford (Wanner) oil guns, but the thing has begun leaking at the join between the brass pump cylinder and Myford's add-on steel nozzle section.

I've tried tightening the connection, but it still leaks quite badly in use.

What would be the correct material for me to use to seal those threads? Teflon tape? Perhaps some Loctite product?

Ignatz, please tell me where you got the oil gun tip from as the club needs one, and yes, PTFE tape will easy cork it oil tight John

[IgnatzParticipant @ignatz]

John, … I ordered that oil gun (complete with the tip) from Myford Ltd.

I don't think they offer that nose piece by itself.

Yes, I paid their (high) price as I felt the cost of the oil gun cheaper than ruining the main spindle of my lathe for lack of lubrication.

I'm including the link below.

I bought one of these guns when first on the market then about 90 gbp ,but it has always leakedwhere you arrowed and ptfe has never cured it ,I have resigned myself to a leaky gun.

@john fletcher …

I seem to have found a Myford (franchise) distributor that offers the oil gun tip you are looking for…

… or at least I think so. You might have to check the threading of your nose piece and make an inquiry via email to be certain.

The website is in Holland.

A translation of the words on the web page:

Extension piece and nozzle for Abnox-Wanner oil gun for the old model oil nipples from Myford.

This concerns the small part next to the oil gun / oil gun not included.

As submitted before – many topics, like this one, have been 'done to death' on here previously.
A quick search (top right) will provide many answers.

Forum thread on Myford & oiling

[noel shelleyParticipant @noelshelley55608]

Much is said about oiling the Myford and what oil to use ! DO NOT use chainsaw chain lube ! For Nutto in the oil gun use a light engine or hydraulic oil to spec SAE 10 or ISO 32, this can be bought in 1L bottles. For slide ways Etc an engine oil to SAE 30 or ISO 68 a straight mineral oil is best not a multi grade, often sold as for classic cars/engines.If you have the quick change gear box then from memory EP 90 gear oil is used.

Since you have a lathe and the original oil gun was notorious for leaking the following may be helpful. A the usual thead for oil and grease guns was 1/8" BSP, (a common thread) and "O" rings are avalable in 4, 5 and 6mm by 2mm section (and many other small sizes) it would not be difficult to make an adaptor or a complete oil gun to solve the leakage problem. May be I should come up with a design ? Noel.

My last contribution to this thread…….and that's to repeat the suggestion to read the earlier thread highlighted above.

For example, therein Simon Collier wrote:- "I fitted to a cheap oil can a brass end with an internal o ring selected to squeeze over my ML7 oil nipples. It was a quick and dirty prototype to test the concept, but it worked so well it remains in service. Works a treat. "

[IgnatzParticipant @ignatz]

@ john fletcher, … I used that PTFE tape on the oil gun connection. First cleaned all the oil off of the threads (both inner and outer) and then gave three tight wraps of the teflon tape after which I tightened up the connection with two pairs of pliers – using suitable amounts of cotton cloth between pliers and fittings to avoid damage to the parts in question.

The oil gun now works a treat. No more leaks from that joint between the brass pump and the steel extension.

Of course, I still get a splash of oil should I not make a perfect connection between nozzle and oil fitting on the lathe, but that's all part of the fun, right!?
