I've been looking at buying or building one of these systems for the past few weeks. Lubricating a cutter and clearing chips manually with my airbrush is getting old quickly!

Ideally i'd like a system where I can use just air to clear chips (useful for materials such as acrylic) or mix coolant into the airflow for aluminium jobs.

I've read all the threads I can find on 'Fogbuster' type systems. The plumbing seems simple enough, but the 'mixing blocks' look like there is quite a bit of work involved.

Since I'd have to source and buy suitable needle valves, taps, fittings etc, I'm wondering whether it's worth taking a punt on one of the ready-made units from China : http://www.aliexpress.com/wholesale?...t=coolant+mist

Has anyone imported something similar rather then making their own or shelling out £500+ for a system from a UK supplier?
