as I reported in a post elsewhere the sight glass on my headstock has an arrangement whereby a white screen is supported behind the glass to make it easier to read. This has now twice become bunged up with gunge making the sight glass look as tho there is oil when there might not have been. I only noticed when pouring more oil in didn't affect the level. The recommended oil (for everything, slides, headstock gearbox etc) is Esso Febis K68, which is primarily a slideway oil. They also state 'oil having anti-oxidation, anti-wear and anti-foaming properties and an approximate Kinematic viscosity of 68 centistokes at 100F'
Any lubrication experts know what they put in slideway oil to make it sticky? Could this be the cause of my gunge? I'm thinking of just buying Hyspin68 or similar hydraulic oil which seems to meet the verbal requirement.

It's a bit risky to continue with Febis, this is the second time this has happened
Lathe is myford 254

Duncan, I use Headstock Oil from Warco - seems to be OK, for me anyway

Duncan ,I have an old Myford S7 with a sight glass.I have used the recomended Myford headstock oil Nuto 32 But Hydraulic oil is the same and I have never had your problem in the sight glass.Because Myford charged too much for their oil I used the hydraulic oil.

if it is clogging up the sight glass i wonder what it is doing to the oilways inside the headstock ?

I'm not familiar with the model of lathe but on my lathe the spindle bearings are lubricated using oil fling off from the gears , wouldn't a tacking agent in the oil cause it to string and not want to fling off ?

I've just bought a second hand 2003 Warco 1330 gear head.

No spec on the oil from Warco, other than the obvious suggestion to use the one they supply as suitable for the job.

They currently specify a different oil for slideway and headstock/gearbox. The old 2003 manual that came with mine suggested a particular brand of 68 weight slideway oil for the headstock. ( can't remember which now and the books' not to hand)

I went to Pennine Lubricants, my local oil specialist in Sheffield and picked up a gallon of their recommended equivalent.

They recommended TX68, which I think was about £2.60 per litre for 5 Litres. Struck me as a good price.
I don't know where in Cheshire you live Duncan, but if it's within easy travelling distance of Buxton, where I now call home, I'll happily pick you up a gallon next time I'm in Sheffield, (provided you contact them first and find their recommended equivalent of the Myford spec oil.)

Clearly they do standard 68 weight hydraulic oil as well.

Check out their web site, lots of different stuff on offer, and they do offer advice over the phone.

Thanks chaps, after reading these comments I'm decided on the normal hydraulic oil. Thanks for the offer peak4, but I can get it from Caldo in St Helens, a lot closer but nothing like as pretty as Buxton

Nuto 32, AWS32, Tellus 32, it's all the same. It's all mineral hydraulic fluid.

Carl, the original query was about slideway oil which has 'tackiness' additives (see the link in peak4's post above). It is not simply mineral hydraulic oil. These additives are I think are gunging up my sightglass. I'm switching to 68 grade mineral hydraulic oil.

I would agree that buying 'special' oil for Myfords in little bottles is an expensive way of doing things.

Apologies. I should have read the op. Just trying to get across that one needn't get hung up on names and such like.

I've seen a lot of people scratching their heads over oils which are all functional equivalents, just with a different name as they are the same product but by different manufacturer.

I use Witham Oils. I expect that if I asked (or perhaps even checked on line), they would supply an equivalent modern oil to the same, or better, specification than the original recommended.

I was one of the head scratchers, struggling to find a source for a particular Shell Vitrea oil which was said by the plate on the lathe to be "obtainable thoroughout the world"! Needless to say, I am now using a suitable hydraulic oil.

In the course of looking I gathered that Shell named their oils after kinds of shell; vitrea is a snail.

Hi

Here goes at my approach to a well trampled path on oils and uses. Any oil is better than no oil but no means ideal.

Headstock gearbox 68 Hydraulic Oil will be OK in almost lathes. Chain saw bar oil has all the tackifiers you will ever need to stick it on ways and sliders cheap and cheerful. The "Experts" tell me that it is water soluble yes but I do NOT use my lathe in the rain only my chainsaw.

Just to finish this off, being tight I drained the old oil into bottles to use for less critical jobs. After about a week this is what I've got, a gungy sediment. No wonder the sight glass didn't like it. Moral, despite what Mr Myford says, don't use slideway oil in your headstock

Duncan, A genuine question, could that be emulsified condensation/water contamination, maybe from soluble cutting oil that's leaked into the gearbox. (maybe even before you bought the lathe if second hand)

I suppose the bottle does say "Cloudy Lemon" laugh

Duncan,

I am interested to know "where" Myford state Febis K68 is for the lubrication other than slideways?

Thank you in advance.

Peak4: I changed the headstock oil a few year a previous blocked sightglass. I haven't used the lathe a lot since due to family issues, and I rarely use soluble oil,anyway. The sediment has a 'fluffy' appearance, not like emulsified oil

Kwil: the Myford 254 manual (or at least my copy) says to use Febis K69 'for all purposes' including headstock. I've changed to an oil that meets the description as in my original post.

I've still to change the oil in the screwcutting gearbox and apron, but it's on the list

correct, 69 was a typo and doesn't exist.
