Thanks for that, however I have already read that full report & it does not give any assistance as to the equivalent.

G'day Bruce,
I have a vague recollection that Velvus was an Atlantic Oil Co company product.
They were bought out by Esso then Mobil so perhaps Mobil Vactra oils might be an equivalent.
I did a quick lookup for Vactra 3 and came up with this link.

Mobil Vactra Oil Numbered Series

Might help.
Cheers,
Greg.

In that PM thread the description of Velus 3 is that it was " almost like water" i bought some Shell light spindle oil last year...Molina 10, and it is very watery. It was supposed to be a direct repalcement for a light Velocite spindle oil.

Phone up your favourite oil company (Shell, Mobil, Fuchs - who ever) and ask their technical people. They usually have a list of all the superseded oils and (their) modern equivalents.

Thanks for that Greg.
I just checked up with an oil specialist bloke I know who is in the oil business, supplies all types of oils.
Discussed the question & application with him, & yes..... as you suggested.....
The recommendation was Shell Morlina 10
A spindle oil which he believes is the closest equiv to Velvus Three.
It was also suggested for use in lathe spindle lubrication.
A 5 litre container would be around $50
So looks like I will go with that.

Bruce

Does it give another description?

Usually something in Saybolt seconds @ x degrees F..

I dont have any additional information on the tech aspects of the oil.
The only thing I have to go by is the original bronze nameplate on the machine which nominates "Velvus Three Oil from the British Petroleum & Turpentine Corp."
I think it may have the original oil in the spindle reservoir, which would be 60 to 70 yrs old.
The machine has been operating well for me for about 20yrs, so I do not want to mess it up.The oil level in the sight glass seemed to be a little low, thats the reason for the enquiry.
Thanks for your interest.

Failing everything else... email the company and ask them Precision Grinding in Manchester: Surface Grinding in Manchester

If you haven't fixed yourself up, there's a 20 litre drum of Morlina surplus to requirements about 25km away if the Hawkesbury behaves!

I have been in contact a number of times with the Churchill people in Manchester England, & they have been most helpful.
Thanks so much for putting me onto the English Co. I have never been able to get much info before on the grinder but now picking up a wealth of information.

i all ways thought that a good quality engine oil was the way to go in a lathe headstock

I would think that good engine oil is OK in plain bearing lathe spindles, but with tapered roller bearings I think that you require a grade oil with EP (extreme pressure) qualities. These two bearing types are different beasts. My thoughts only.

good point. Ill have to think about that.
