Myford super 7 cross slide and oil gun

Couple of questions in single post just to confuse the issue! First,sticking cross slide dial, all ok when pulling slide back towards me but dial doesn't always move when traversing away. Looked in the book and the adjusting collar and lock screw only takes up free play in feedscrew, the bell type washer is supposed to give the friction to the dial, where do I look to adjust if possible? Second, have a Wanner oil gun, which when I saw the price almost gave me a heart attack, and it is to be frank useless. Oil floods past whatever seals are supposed to stop it and you have no way of knowing if any passes thru nipple. As most of the nipples are vertical could I not just replace these with the lift top oilers as I assume most oiling is gravity fed and not pressurised? John

The washer can be given more dish with a tap from a soft hammer.

If you have recently acquired your myford it will be worth making a few checks. Previous owners have been known to squirt grease in the oilers, and this prevents any oil getting in ever again. A quick look at the apron (I am assuming that your Super is similar to my ML7) and there is an oiler for the carriage manual travel system. Mine was full of brown (ie old) grease, that's how I know.

Hope this helps

If yours is the model 300-1 Wanner then it is probably the best of a bad bunch. Mine works better with an O ring slipped on to the nipple before use.

Tim Stevens is spot on with his comment: there is no known way of preventing folk from pumping grease into oilways.

Some have fitted hydraulic nipples but then you need to find a suitable oil gun to work with them. I agree oil cups could be fitted in most cases but they would tend to catch on the cleaning rag.

It's more the fact the oil pi***s out from the moving shafts as you press it down! Lubricates everywhere other than where it's supposed to!

The simple solution is to tear off a scrap of paper towel and place it between the nipple and the oilgun. Then squirt away,

I put lift-top oilers in several places on my ML7, notably on the headstock bearings in place of the ever-feeding-no-matter-if-I-turned-them-off oilers and also on the motor pulley bracket. I've used them for a couple of years now and haven't had any problems.

If your cross slide dial is slipping when you turn the ball handle it can only be because it's rubbing against the end bracket. This seems to be confirmed by the observation that it doesn't slip when you turn the handle the other way - presumably the backlash is moving the dial just clear of the bracket when you wind the slide outwards.There should be visible clearance between the dial and the end bracket. If you don't have this you may need to skim a couple of thou or so off the back face of the dial. HTH. Mike

My Wanner oil gun was initially the answer to my prayers - it actually worked. However after a few years the piston type oil seal in the reservoir started to leak so if used horizontally I always oiled one of my hands. A couple of years ago at a show I asked Myfords about a replacement seal and was told that they had none but they wish they did. It was one of the more common requests.

Since then I have tolerated the leak and frequently thought about replacing the useless seal with an aluminium disc carrying an O-ring.

I had the same problem with the dial on my new S7. Turned out there was slight barring on the end of the collar from the graduations, which I lapped away on a diamond plate. End of problem.

Thanks for all your pointers will report back once I have hopefully sorted the issues! Dial is a mechanical issue to sort, oil problem seems to be crap design! John

I bought a genuine Myford oil gun. From new it leaked everywhere, more oil on machine and me than where it was required.

Bought a Reilang, money very well spent. It does not leak, and puts the oil where you want it go, and will pump no matter what angle its at!.

I have fitted hydraulic nipples everywhere and use a Reilang fitted with the matching hydraulic "socket".

I have a lathe with ball oilers. The oil guns for these are cheap, (around £2.50) usually come with a long spout and a flexible tube, plenty of pressure and work very well. I made a replacement nozzle for one of these to use on my Myford, just a tube to fit over the nipple with an O ring at the bottom, brilliant at getting the oil where it needed to go. Not entirely leak free because once the oil is in the nozzle it stays there (non return valve) and tends to drip. I just stand my oil guns in a tray and give them a wipe with a rag, keeps the paintwork in good condition.
