Ethanol mist for cutting aluminium

[matt-b2]

Well your doing it wrong then.

Hi Dean - I have no doubt in my mind that you're absolutely right. I'd love to run without any coolant, I've seen plenty of videos of other machines (yours included) happily munching through aluminium without any coolant present, so I know it must be possible, but I've not achieved it yet. Clearly I need to experiment more. So far, I've tended to play it safe by running plenty of coolant just because, for me at least, it leads to less disasters, even if it's a sub-optimal way of doing things.

Matt.
