The history book suggests that Wakefield's started with nothing more
than Castor Oil. I should think that it will cut most things merely
being close to tooling.
The esterification or saponification of Fatty Acids.It all depends- if

Is castor oil itself any good ?
Think I'll have a go with shower gel - smells nicer.
Neither of those are saponified of course. Is it the saponification that
makes them good cutting lubricants ?
Is soap any good for thread cutting ? In Woowlich Arsenal I was told that

Do a google for soluble oils.Loads of manufacturers and unless you`re

litres when mixed.If it`s only for a Myford or similar go and knock on
some engineers doors to buy a litre.If you had been near I would have
given you some but I`m not posting it.
Rocol make excellent cutting paste & liquid (Rocol RTD), have used
very successfully on stainless steels. I think ARCO stock it or
definitely Axminster Tools (no connection, just satisfied customer).
Also look out for similar compound called Trefolex.
For trouble free tapping. Mix together one part Turpentine, two parts
White Spirit and three parts Olive oil.
hope this is of use MARK
I have used Rocol RTD cleancut fluid and find it excellent.
It leaves little residue and I`ve used it for drilling, tapping and on
my lathe and milling cutters. I apply a small amount using a childs
