I'm getting braver and am thinking about cutting some brackets for limit switches next week but can I use 3 'n' 1 oil as a coolant or WD40 ??

3in 1 oil is too sticky WD40 works good on Ali. Any dewatering fluid will work good so buy the cheapist you can, WD40 is expensive.

If you plan on doing lots of Ali cutting drop me aline because I sell a WD40 equivelent that's less than half the price. Only thing is I only sell it by the case 12x500ml aerosols.

Can make cheap alternative to WD40 with paraffin and some other stuff, google it.
The 'proper' coolant you see on all the youtube videos is oil diluted about 50:1 with tap water. I've got loads of it if you want a pint :beer:
