Cutting aluminium without oil/coolant

[Desertboy]

Hi I'm going to fit an MDF bed to my router mostly because an ecocast bed will cost £583+vat which is over 1/2 what I spent on building the router lol. 95% of what I will process will be wood/mdf but occasionally I want to do aluminum (EG make plates for another router) but of course if I use coolant it will knacker my mdf bed.

I was wondering if people had success cutting aluminium using only compressed air to clear the chips? Speed will not be an issue so I could take it very slow and shallow cuts to compensate.

Thanks
